Answer:

  -2x^3 +13x^2 +3x -54

Step-by-step explanation:

The product is found using the distributive property.

  (x -6)(-2x^2 +x +9) = x(-2x^2 +x +9) -6(-2x^2 +x +9)

  = -2x^3 +x^2 +9x +12x^2 -6x -54

Answer:

P(t) = 258( 1 + 6%)^t

Step-by-step explanation:

Given that the  population of caribou in a forest grows at a rate of 6% every year. If there are currently 258 caribou, the function representing the number of caribou in the forest in t years will be

P(t) = 258( 1 + 6%)^t

Since it is increasing, it will be 1 + 6%

Where P(t) is the function representing the population after t years.

258 is the current or initial population.

Hey there!

2x+9+103=180

2x+112=180

2x=68

x=34

Let me know if this helps :)

Answer:

34 degrees

Step-by-step explanation:

(2x+9) degrees and 103 degrees  form a linear pair

Therfore, the sum of these two angles = 180

(2x+9)+103=180

=>2x+112=180

=>2x=180-112

=>2x=68

=>x=68/2

=>x=34

The value of x is 34 degrees

Answer:

55°

Step-by-step explanation:

What we have are vertical angles. Vertical angles are angles directly opposite to one another.

Importantly, the measures of vertical angles are equivalent. Thus, set the expressions to each other and solve for x:

[tex]3x+34=7x+6[/tex]

Subtract 3x from both sides:

[tex]34=4x+6[/tex]

Subtract 6 from both sides:

[tex]28=4x[/tex]

Divide everything by 4:

[tex]7=x[/tex]

Flip:

[tex]x=7[/tex]

Now, substitute this back into either of the equations since we know they are the same:

[tex]3x+34\\=3(7)+34[/tex]

Multiply:

[tex]=21+34[/tex]

Add:

[tex]=55[/tex]

So, the angle is 55°

Answer:

m<ABC = 45

m<DBC = 34°

Step-by-step explanation:

Given:

m<ABD = 79°

m<ABC = (8x - 3)°

m<DBC = (5x + 4)°

Step 1: Generate an equation to find the value of x

m<ABC + m<DBC = m<ABD (angle addition postulate)

(8x - 3) + (5x + 4) = 79

Solve for x

8x - 3 + 5x + 4 = 79

13x + 1 = 79

Subtract 1 from both sides

13x + 1 - 1 = 79 - 1

13x = 78

Divide both sides by 13

x = 6

Step 2: find m<ABC and m<DBC by plugging the value of x into the expression of each angle

m<ABC = (8x - 3)°

m<ABC = 8(6) - 3 = 48 - 3 = 45°

m<DBC = (5x + 4)°

m<DBC = 5(6) + 4 = 30 + 4 = 34°

Answer:

[tex]\huge\boxed{\sf a = \frac{6-3x}{y} }[/tex]

Step-by-step explanation:

3x + ay = 6

Subtracting 3x to both sides

ay = 6 - 3x

Dividing both sides by y

[tex]\sf a = \frac{6-3x}{y}[/tex]

Answer:

If statement(1) holds true, it is correct that [tex]\small \frac{r}{s}[/tex] is an integer.

If statement(2) holds true, it is not necessarily correct that [tex]\small \frac{r}{s}[/tex] is an integer.

Step-by-step explanation:

Given two positive integers [tex]r[/tex] and [tex]s[/tex].

To check whether [tex]\small \frac{r}{s}[/tex] is an integer:

Condition (1):

Every factor of [tex]s[/tex] is also a factor of [tex]r[/tex].

[tex]r \geq s[/tex]

Let us consider an example:

[tex]s = 5^2 \cdot 2\\r = 5^3 \cdot 2^2[/tex]

[tex]\dfrac{r}{s} = \dfrac{5^3\cdot2^2}{5^2\cdot2} = 10[/tex]

which is an integer.

Actually, in this situation [tex]s[/tex] is a factor of [tex]r[/tex].

Condition 2:

Every prime factor of s is also a prime factor of r.

(But the powers of prime factors need not be equal as we are not given the conditions related to powers of prime factors.)

Let

[tex]r = 2^2\cdot 5\\s =2^4\cdot 5[/tex]

[tex]\dfrac{r}{s} = \dfrac{2^3\cdot5}{2^4\cdot5} = \dfrac{1}{2}[/tex]

which is not an integer.

So, the answer is:

If statement(1) holds true, it is correct that [tex]\small \frac{r}{s}[/tex] is an integer.

If statement(2) holds true, it is not necessarily correct that [tex]\small \frac{r}{s}[/tex] is an integer.

Answer:

This is a graph problem

Step-by-step explanation:

on a ten by ten graph this is the included file

(sorry for my bad lines, i had to do this with a mouse0

Answer:

  see the attachment for a graph

Step-by-step explanation:

We can't tell what your instructions are. Many graphing tools will let you click on the locations of the points, then draw a line through them. The attached image is from one such tool.

__

If you want to plot this by hand, you do it essentially the same way: plot the two points and draw a line through them.

If you want to write an equation for the line, you can start with the 2-point form:

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (5 -(-3))/(2 -(-4))(x -(-4)) -3

  y = 8/6(x +4) -3

  y = 4/3x +16/3 -9/3

  y = 4/3x +7/3

__

Personally, about the only thing useful I find in this equation is that it tells you the slope is 4/3. You can determine the same thing by counting grid squares between the plotted points on the graph. The line goes up 8 for each 6 to the right, so slope = rise/run = 8/6 = 4/3.

Answer:

Explanation: The sum of the lengths of any two sides of a triangle must exceed the length of the third side; therefore, 5+7 > x, which cannot happen if x = 13.

Step-by-step explanation:

x + y = 16 (*)

x^2 + y^2 = 146 (**)

(*) <=> x= 16-y

substitute x = 16 - y

(**) <=> (16-y)^2 + y^2 = 146

<=> y^2 - 2.16.y + 16^2 + y^2 = 146

<=> 2y^2 - 32y + 110 = 0

<=> y^2 - 16y + 55 = 0

<=> (y-11)(y-5) = 0

<=> y=11 or y= 5

For y = 11, we have x= 16-11=5

For y=5, we have x= 16-5=11

Step 3: Write coordinates

(0, 2)

Answer:

RP/SP =3 , RP/RS = 3/4

Step-by-step explanation:

Here is the complete question

Three colinear points on the coordinate plane are R(x,y) S(x+8h, y+8k) and P(x+6h,y+6k) Determine value of RP/SP and RP/RS?

Solution

We first find the length of RS, SP and RP as follows

RS = S(x+8h, y+8k)  - R(x,y)

= √[((x + 8h) - x)² + ((y + 8k) - y)²]

= √[x - x + 8h)² + (y - y + 8k)²]

= √[(8h)² + (8k)²] = 8√(h² + k²)

SP = P(x + 6h,y + 6k) - S(x+8h, y+8k)  

= √[((x + 6h) - (x + 8h))² + ((y + 6h) - (y + 8k))²]

= √[x - x + 6h - 8h)² + (y - y + 6k - 8k)²]

= √[(-2h)² + (-2k)²] = 2√(h² + k²)

RP = P(x+6h, y+6k)  - R(x,y)

= √[((x + 6h) - x)² + ((y + 6k) - y)²]

= √[x - x + 6h)² + (y - y + 6k)²]

= √[(6h)² + (6k)²] = 6√(h² + k²)

So, RP/SP = 6√(h² + k²)/2√(h² + k²)

= 6/2

= 3

RP/RS = 6√(h² + k²)/8√(h² + k²)

= 6/8

= 3/4

Hi there! :)

Answer:

Formula: 60t = 360

Solved: t = 6 hours.

Given:

Speed of car = 60 mph

Total distance = 360 miles

Remember, the formula to solve for time (t) given distance (d) and speed (s)  is t = d / s, or t · s = d.

Substitute in the known values, and let "t" represent the time needed:

60 · t = 360

Solve:

Answer:

18.6

Step-by-step explanation:

Adding -20.4 to 39 is the same as subtracting 20.4 from 39. 39 - 20.4 = 18.6.

Answer:

See each problem number below for answers.

Step-by-step explanation:

To solve this problem, we must remember the rules of addition and subtraction.  If we are adding a negative, this is the same thing as subtracting a positive number (because subtraction is defined as the addition of a negative number).  In addition, if we are subtracting a negative number, the two negative signs cancel each other out, and we are left with addition of a positive number.  Let's use these rules in the problems you have given.

1) 2 - (-73)

Since the subtraction of a negative is the same as addition, we can rewrite this as:

2 + 73

which is a simple computation and leaves us with:

75

2) 39 + (-20.4)

The addition of a negative is the same as subtraction, so we can rewrite this as:

39 - 20.4

which is a simple computation and yields:

18.6

3) 67.086 - (-20)

The subtraction of a negative is the same as addition (similar to problem 1)

67.086 + 20 = 87.086

4) 60 + (-19)

The addition of a negative is the same as subtraction (similar to problem 2)

60 - 19 = 41

5) 87 - 64.05

This is a simple subtraction problem, the computation gives us the answer of:

87 - 64.05 = 22.95
