What is the simplified form of



30y2|xz3|

30x2y2z4

360xy2|xz3|

360xy2|z3|

Answer:

(-6, 0) and (3, 0).

Step-by-step explanation:

There are actually 2 x-intercepts. You will get the x-intercept when f(x) = 0.

f(x) will equal 0 when either (x + 6) = 0 or (x - 3) = 0.

x + 6 = 0

x = -6

x - 3 = 0

x = 3

So, your two x-intercepts will be at (-6, 0) and (3, 0).

The correct option is:

14 inches

Step-by-step explanation:

The question is incomplete because the picture of the flap is not shown in the question nor the measurements are given. First lets complete the question. The figure was this question is attached below.

We can see that the bottom width of the trapezoid is 9 inches, the top width of the trapezoid is 5 inches, and it has a height of 2 inches.

The area of trapezoid is given as:

Area = ((Top width + Bottom width)/2) · h

Area = ((9+5)/2) · 2

Area = (14/2) · 2

Area = 7 · 2

Area = 14 inch²

Answer:

To make 10 pancakes with this recipe, 6 cups of milk are needed.

Step-by-step explanation:

Since we know that 3 cups of milk are needed for 5 pancakes, we need to double the 5 pancakes to get to 10 pancakes.

5 × 2 = 10

Since 5 times 2 is 10, we also need to double the  3 cups of milk.

3 × 2 = 6

This gets us to 6 cups of milk. All we needed to do was multiply the recipe based on how many pancakes we want! Yum!

Answer:

The correct option is A:

A) Time of flight = 7 hours 5 minutes

Step-by-step explanation:

If

For eastern time zone, t = 12:00 pm

Then, pacific time zone , t =  9:00 am

Which means the pacific time lags 3 hours to eastern time

Time of departure = 9:15 am (eastern time)

TIme of arrival = 1:20 pm (pacific time)

Either convert both of them into eastarn time zone or pacific time zone to find the time of the flight. The answer for both will be the same.

Converting both in pacific time zone.

Time of arrival = 1:20 pm (pacific time)

Time of departure = (9:15 am (eastern time) - 3 hours) (pacific time)

Time of departure =  6:15am (pacific time)

Time of flight = Time of arrival - Time of departure

Time of flight = 1:20pm - 6:15am

Time of flight = 7 hours 5 minutes

Answer:

B. (x - 5)

Step-by-step explanation:

Looking at the graph, you can find the solutions of the function by seeing where it crosses the x-axis.

In this case, the function crosses the x-axis at the point (5,0), which is represented by (x - 5) because it is 5 units to the right of the origin.

Answer:

B

Step-by-step explanation:

Looking at the graph, we see it intersects the x-axis at -2 and 5, which means our factors, which are of the form x - a, are x + 2 and x - 5.

From the answer choices, we see that only B matches. The answer is thus B.

Answer:

The correct answer is letter B.

Step-by-step explanation:

In order to shift any function f(x) in the vertical direction we need to add or subtract the constant number we want to move. In this case we want to shift the function up by 4 units, therefore we need to add 4. The new function, g(x), is shown below.

[tex]f(x) = 5*(x + 2)^2 - 3[/tex]

[tex]g(x) = f(x) + 4\\g(x) = 5*(x+2)^2 - 3 + 4\\g(x) = 5*(x + 2)^2 + 1[/tex]

The correct answer is letter B.

Answer:

The answer is given below

Step-by-step explanation:

Let the number of passengers that boarded the bus at the interchange be x.

At the first  bus stop, 1/4 of the passengers alighted the bus and 6 people boarded the  bus.

Therefore The number of passengers when the bus left the first bus stop = [tex]x-\frac{1}{4}x +6=\frac{3}{4}x+6[/tex]

At the 2nd bus stop, 8/15 of the passengers alighted and 10 passengers  boarded the bus.

Therefore The number of passengers when the bus left the second bus stop

[tex]=\frac{3}{4}x+6-\frac{8}{15}( \frac{3}{4}x+6)+10=\frac{3}{4}x+6-\frac{8}{20}x-3.2+10\\\\=\frac{7}{20}x+12.8[/tex]

Given that there were 24 passengers on the bus when it left the  2nd bus stop

[tex]\frac{7}{20}x+12.8=24\\7x+256=480\\7x=480-256\\7x=224\\x=32[/tex]

Therefore 32 passengers boarded the bus at the interchange

Answer:

Find a common denominator on the right side of the equation

Step-by-step explanation:

I was taking the test and couldn't find the answer to this question anywhere so let me help you out...  

abidemiokin provided a wonderful step-by-step explanation for solving the formula, but left out the actual answer for the question which is what I'm here for. I read through abidemiokin's explanation and reviewed my options before choosing the best answer. As you see in step 5 of my edited version of abidemiokin's explanation the missing step is there. In the provided question we see steps 1,2, 3, and 4 being identical to those in the explanation below. From this, it is clear the next step (step 5) would be the next step, and as it is one of the options we can trust that it is correct.

(If you still have doubts then trust the fact that I took the test and the answer I provided above was indeed correct.)

Given the quadratic equation ax²+bx+c = 0, to derive the quadratic formula from the equation, the following steps must be followed;

ax²+bx+c = 0

Step 1: Subtract c from both sides

ax²+bx+c-c = 0-c

ax²+bx = -c

Step 2: Divide both sides of the equation by a

ax²/a + bx/a = -c/a

x² + bx/a = -c/a

Step 3: Complete the square and add the quantity (b/2a)² times a squared to both sides

x² + bx/a +  (b/2a)² = -c/a +  (b/2a)²

Step 4: Square the quantity  b/2a on the right side of the equation

x² + bx/a +  (b/2a)² =  -c/a +  b²/4a²

Step 5: Find a common denominator on the right side of the equation which is 4a²

x² + bx/a +  (b/2a)² =  -4ac/4a² +  b²/4a²

Step 6: Add the fractions together on the right side of the equation

x² + bx/a +  (b/2a)² =  (-4ac+  b²)/4a²

Note: The fraction at the right-hand side of the equation is to be added together not multiplied as shown in the question.

Step 7: The equation on the left is to be written as a perfect square as shown

(x+b/2a)² =  (-4ac+  b²)/4a²

Step 8: Take the square root of both sides

√(x+b/2a)² = √ (-4ac+  b²)/4a²

(x+b/2a) =  √(-4ac+  b²)/2a

Step 9: subtract b/2a from both sides

x+b/2a - b/2a =  -b/2a + √(-4ac+  b²)/2a

x =  -b/2a + √(-4ac+  b²)/2a

Step 10: Add the fractions together on the right-hand side

x =  -b±√(-4ac+  b²)/2a

This gives the required equation

Answer: A  Find a common denominator on the right side of the equation

Answer:

x = 8

Step-by-step explanation:

Let us take the breadth as 'x'

breadth = x

length = 3 + x

perimeter = 38m

perimeter of a rectangle = 2 ( l + b )

= 2( x + x + 3 ) = 38

4x + 6 = 38

4x = 38-6

x = 32/4

x = 8

breadth = 8

length = 11

Answer:

Step-by-step explanation:

I think your determinant is

 3   -3

-5   -6

To evaluate this, multiply diagonally:  (3)(-6) = -18, followed by -(5)(-6), or 30.

The value of the determinant is then 30 - 18, or 12.

Review:  if you multiply DOWN, as we did with (3) and (-6), we give the product the + sign:  +(3)(-6) = -18;

if you multiply UP, as we did with (5)(-6), we give the product the negative sign:  -(5)(-6) = +30

I urge you to read the rules on evaluating determinants.

Answer:

2

Step-by-step explanation:

I think the answer is 2, because 2a=4, but when simplified, you can divide both the numerator and denominator by 2, making the denominator 4/2= 2.

The missing denominator of the solution is 2.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have,

2x² + 10x -6 = 0

Now, using Discriminant Method

x = [ -b ± √ (b² -4ac)] / 2a

Here, a= 2, b= 10 and c=-6

So, x = [ -10 ± √(10² - 4(2)(-6)] / 2(2)

x = [ -10 ± √ 100 + 48]/ 4

x = (-10 ± 2√37)/ 4

x = (-5 ± √37)/2

Answer:

No change in angle it will remain 6 degrees only.

Step-by-step explanation:

measurement of angle on paper = 6 degrees

power of magnifying glass = a*6

it means that the glass enlarges any thing seen through it by 6 times.

so if you are watching 1 cm object, it will be 1*6 times larger (i.e 6 cm) when seen through the magnifying glass.

It is to be noted that glass changes the size of the object, it does not change the shape of object. Th object will remain similar to the older one.

________________________________________________

Now given that

measurement of angle on paper = 6 degrees

This is a tricky question, here change of size of object is not being asked .

Since angle determines the shape of object , so angle will remain similar to as that on paper only size will get enlarged.

Hence, the measure of angle will remain same i.e 6 six degrees only. It will not change.

only thing will be that the shape of angle will appear larger but there will be no impact on angle.

Option C.

Step-by-step explanation:

Note: In option C interval should be (-1,1) instead of [-1,1].

From the given table it is clear that the value of f(x) is 0 at x=-1 and x=1.

The value of f(x) is negative over the interval [tex](\infty,-1)\text{ and }(1,\infty)[/tex]. So,

[tex]f(x)<0[/tex] over the interval [tex](\infty,-1)\text{ and }(1,\infty)[/tex]

Answer:

X = 4

Step-by-step explanation:

First, You need to rewrite the expression to look like this

9 - 3x = 12

An inequality basically means equals and the next step is to subtract 9 from both sides so it would look like this

3x = 12

Then divide both sides by 3 to get

x = 4

Answer:

$325

Step-by-step explanation:

Let x be the price of the washer.

Let y be the price of the dryer.

x + y = 708

x = y + 58

Put x as y+58 in the first equation and solve for y.

y + 58 + y = 708

2y + 58 = 708

2y = 650

y = 650/2

y = 325

Put y as 325 in the second equation and solve for x.

x = 325 + 58

x = 383

The cost of the washer is $383.

The cost of the dryer is $325.

Answer:

Step-by-step explanation:

Cost of dryer = $ d

Cost of washer = d + 58

Total cost = $ 708

d + (d + 58) = 708

2d + 58 = 708

         2d = 708 - 58

         2d = 650

           d = 650/2

      d = 325

Cost of washer = 325 + 58 = $ 383

Cost of dryer = $ 325

Step-by-step explanation:

115°=17x-4

adding 4 on both sides

115°+4=17x-4+4

119°=17x

dividing 17 on both sides

119°/17=17x/17

x=7

now we find the measure of angle

17(7)-4

=119-4

=115° same as angle R

Answer:

x = 7

115°

Step-by-step explanation:

Opposite angles in a parallelogram are equal.

17x - 4 = 115

Add 4 on both sides.

17x = 115 + 4

17x = 119

Divide 17 on both sides.

x = 119/17

x = 7

Plug x as 7 in angle T.

17(7) - 4

119 - 4

= 115

x= (100*46.5)/93 = 50

so the initial price of the coat is 50 pounds

The jumper costs 32.8 pounds after an increase of 6 percent

so:

using proportionality:

x= (100*32.8)/106 = 30.94

the initial price is 30.94 pounds

Answer:

a. £50

b. £30.94

Step-by-step explanation:
