Solving Quadratics



Solve for all values of x by factoring. x² + 4x + 5 = -6x + 5​

Answer:

x = 0

Step-by-step explanation:

Given

2 + 9x = 3(4x + 1) - 1 ← distribute and simplify right side

2 + 9x = 12x + 3 - 1

2 + 9x = 12x + 2 ( subtract 9x from both sides )

2 = 3x + 2 ( subtract 2 from both sides )

0 = 3x ( divide both sides by 3 )

x = 0

Answer:

x = 9/8

Step-by-step explanation:

Step 1: Write out equation

3(x + 2) = -5(x - 3)

Step 2: Distribute

3x + 6 = -5x + 15

Step 3: Add 5x on both sides

8x + 6 = 15

Step 4: Subtract 6 on both sides

8x = 9

Step 5: Divide both sides by 8

x = 9/8

Answer: 9/8

Answer:

a = 4 b = 5

Step-by-step explanation:

8a + 12b = 92......eqn 1

6a - 4b = 4......eqn 2

multiply eqn 2 by 3

18a - 12b = 12.....eqn 2

add eqn 1 and 2 to eliminate b

26a = 104

a = 4

put a = 4 into eqn 2

18(4) - 12b = 12

72 - 12b = 12

72 - 12 = 12b

60 = 12b

5 = b

Answer:

y = 5x + 3 (or, any line with the slope equal to 5 and a different y-intercept)

Step-by-step explanation:

Parallel lines will have the same slope.

So, a line such as y = 5x + 3 will be parallel because it has the same slope as the original line, which is 5.

There are almost an infinite amount of parallel lines, it just has to have the same slope and a different y-intercept.

Lines like y = 5x + 1 and y = 5x are also parallel.

Answer:

y=5x-8

Explanation:

A line that is parallel to another has the same slope.

The difference between these is where they cross the y-axis.

Answer:

[tex]y=2x-3[/tex]

Step-by-step explanation:

So we want to find an equation in slope-intercept form that is parallel to:

[tex]y=2x+5[/tex]

And contains the point (4,5).

So to create the equation, we will need to slope and the y-intercept.

First, recall that parallel lines have the same slope. Since we want our equation to be parallel to y=2x+5, this means that the slope of the new equation must be 2.

Now, we can use the point-slope form to solve for the y-intercept. The point slope form is:

[tex]y-y_1=m(x-x_1)[/tex]

Let (4,5) be x₁ and y₁. m is 2 since it's parallel to y=2x+5. Thus:

[tex]y-5=2(x-4)\\[/tex]

Distribute:

[tex]y-5=2x-8[/tex]

Add 5 to both sides:

[tex]y=2x-3[/tex]

And that's our equation :)

=======================================

The commutative property of addition is where we can add two numbers in any order we want. Example: 2+3 = 5 and 3+2 = 5.

In general, the rule is x+y = y+x.

In our case, 2x and 15 can be added in any order. So that's why 2x+15 is the same as 15+2x.

-------

Side note: a similar rule applies for multiplication as well. This is called the commutative property of multiplication. Example: 9*3 = 27 and 3*9 = 27. So we can say x*y = y*x.

Each pair of pants:

$24

Step-by-step explanation:

Equation:

60 - 2p = 12

Solve:

-2p = 12 - 60

-2p = -48

p = -48/-2

p = 24

Ceck:

60 - 2*24 = 12

60 - 48 = 12

Answer:

The correct answer is -21 degrees.

Step-by-step explanation:

We know that the original temperature was -12 degrees.  If the temperature drops another 9 degrees, this means that it is getting colder or the temperature is getting lower; this lets us know that we should subtract 9 from the original temperature.  This is modeled below:

-12 - 9

Now, we simply have to perform the subtraction to get:

-21 degrees

Answer:

29th term = 76.4

Step-by-step explanation:

Total terms = 55

aₙ = a + (n - 1) d

5th term = a₅ = 14

   a + (5 - 1)*d = 14

   a + 4d = 14  --------------------(I)

last term = a₅₅ = 144

               a + (55 - 1)d = 144

      a + 54d = 144----------------(II)

Multiply equation (II) by (-1)

(I)             a +  4d = 14

(II)*(-1)     -a - 54d = -144  {Now add and thus a will be eliminated}

                   -50d = -130

 d = -130/-50

d = 2.6

Plug in d = 2.6 in equation (I)

a + 4* 2.6 = 14

  a  + 10.4 = 14

              a = 14 - 10.4

              a = 3.6

29th term = a₂₉ =  3.6 + (29 - 1)* 2.6

                          = 3.6 + 28* 2.6

                          = 3.6 + 72.8

                     a₂₉ =  76.4

Answer:

76.4

Step-by-step explanation:

Let the first term and common difference of the AP be a and D respectively.

[tex]t_5 = 14 \implies \: a + 4d = 14....(1) \\ t_{55} = 144 \implies \: a + 54d = 144....(2) \\ subtract \: eqution \: (1) \: from \: equatin \: (2) \\ \\ a + 54d - (a + 4d) = 144 - 14 \\ a + 54d - a - 4d = 130 \\ 50d = 130 \\ d = \frac{130}{50} \\ \huge \red{ \boxed{ d = 2.6}} \\ substituting \: d = 2.6 \: in \: equation \: (1) \\ \\ a + 4 \times 2.6 = 14 \\ a + 10.4 = 14 \\ a = 14 - 10.4 \\ \huge \purple{ \boxed{ a = 3.6}} \\ \\ t_{29} = a + 28d \\ t_{29} = 3.6 + 28 \times 2.6 \\ t_{29} = 3.6 + 72.8 \\\huge \orange{ \boxed{ t_{29} = 76.4}} \\ [/tex]

Answer:

43°

Step-by-step explanation:

Complementary angles add up to 90° in measurement.

One angle is 47 degrees.

[tex]90-47=\boxed{43}[/tex]

The measurement of the other angle would be 43°.

Hope this helps.

The measure of other angle is 43 degree.

Complementary angles are those whose combined angle is 90 degrees or less. To put it another way, two angles are said to be complimentary if they combine to make a right angle. In this case, we say that the two angles work well together.

Given that.

Two angles are complementary.

Now consider one angle = x degree

And other angle  = y degree

Then according to question,

Measure of angle x = 47 degree

We know that,

The sum of complementary angles are equal to 90 degree.

Therefore,

x + y = 90

x + 47 = 90

       x = 90 - 47

       x  = 43

Hence, the other angle is = 43 degree.

Assuming the question is asking how much time it takes each way, the answer would be 2 minutes from the hive to the flowerbed and 3 minutes back.

Assuming the question is the amount of distance between the hive and the flower bed, the answer is 1080 feet.

Step-by-step explanation:

So the total amount of time it was away from the hive was 20 minutes. Out of those 20 minutes, 15 minutes were spent in the flowerbed. So that means travel time was 5 minutes. Now, going is 9 and coming back is 6, so 9+6=15, 5/15=1/3, 1/3*9=3 and 1/3*6=2

Knowing that information, lets solve what the question could be because I have no idea. The amount of distance from the hive to the flower bed is 1080 feet. I got this by doing 9 (the amount of feet per second) times 120 (the amount of seconds in 3 minutes.) You could do this with 6 but I found it easier to multiply 9*120 compared to 6*180.

If it's the commute time, we already solved that.

=====================================================

Explanation:

Line PR is tangent to the circle at point T. Angle PTO is 90 degrees because of this.

Angle TON is 124 degrees. Triangle TON is isosceles (since we have two sides of the triangle TO and ON equal to the radius). Therefore angles OTN and ONT are equal base angles. Call these x for now

-------

Since 3 angles of any triangle always add to 180, we can say...

x+x+124 = 180

2x+124 = 180

2x = 180-124

2x = 56

x = 28

Therefore,

angle PTN = (angle PTO) + (angle OTN)

angle PTN = 90 + 28

angle PTN = 118

Answer:

[tex]\frac{18}{55}[/tex]

Step-by-step explanation:

Which fraction is bigger? [tex]\frac{27}{75}[/tex] or [tex]\frac{18}{55}[/tex]

If you look closely the fraction [tex]\frac{27}{75}[/tex] , it looks big but it actually isn't.

The fraction that is bigger is [tex]\frac{18}{55}[/tex] . This is because 75 is a big number and its only 27 out of the 75. In [tex]\frac{18}{55}[/tex] , it's not as big as 75. So compare 18 and 27 and 75 and 55. 75 is 20 more than 55. The number 27 is only 9 bigger than 18.

That's why your answer is
