Answer:

The integer that represents the change in the temperature each week = 5

The temperature of the weather drops 5°F each week

Step-by-step explanation:

The given parameters regarding the weather are;

The range over which the temperature dropped = 20°F

The duration over which the temperature dropped = 4 weeks

The rate at which the weather dropped each week = The same amount (constant rate)

Therefore, we have;

For a constant rate of change, the rate of change of the temperature of the weather, m, is given as follows;

m = (The change in the temperature)/(The duration of the change)

m = 20°F/(4 weeks) = 5°F/week

The integer that represents the change in the temperature each week = 5

Find the perimeter of a triangle garden that measures 10 feet by x feet by (2 x+7) feet . Use p=a+b+c
tigry1 [53]

P = 10 + x + 2x + 7

= (10 + 7) + (x + 2x)

= 17 + 3x

Therefore, the perimeter is 17 + 3x feet.

What equation represents the linear function shown in the graph? Enter your answer in the box. Write your answer in the form y =
julia-pushkina [17]
You can take the first point as the origin O(0,0) and the second one (-2,0.5) for easier calculations.
Find the slope, m = (y2 - y1)/(x2 - x1)
= -2-0 / -0.5-0 = 2/0.5 = 4

now take (x,y) = (0,0) and m= 4
use the point slope form
(y - y1) = m(x - x1)
(y - 0) = (4)(x - 0) ......taking (x1,y1) = (0,0)
y = 4x + 0 ...... in the form of y = mx + b
I hope I was helpful:)

Get the equation of the line containing PQ using the point-slope formula:

<em>y</em> - (-2) = 3/2 (<em>x</em> - (-6))

Solve for <em>y</em> to get it in slope-intercept form:

<em>y</em> = 3/2 <em>x</em> + 7

so the <em>y</em>-intercept is (0, 7).

The line containing QR is then

<em>y</em> - 7 = -3/4 (<em>x</em> - 0)

or

<em>y</em> = -3/4 <em>x</em> + 7

The point R is on the <em>x</em>-axis, so its <em>y</em>-coordinate is 0. Plug in <em>y</em> = 0 and solve for <em>x</em> to get the other coordinate:

0 = -3/4 <em>x</em> + 7

3/4 <em>x</em> = 7

<em>x</em> = 4/3×7 = 28/3

So the point R has coordinates (28/3, 0).

Need Help with some Math
tatyana61 [14]

Answer:

8

Step-by-step explanation:

We can use the Polynomial Remainder Theorem. The PRT states that if we have a polynomial f(x) being divided by a factor in the form of (x-a), then the remainder of the polynomial is given by f(a).

We have the polynomial:

f(x)=3x^{15}-5x^{12}+7x^6-3x^2+12

And it is being divided by:

(x+1)

We can rewrite our factor as:

(x-(-1))

Therefore:

a=-1

Then our remainder will be:

f(-1)

Evaluate:

\begin{aligned} f(-1)&=3(-1)^{15}-5(-1)^{12}+7(-1)^6-3(-1)^2+12\\&=-3-5+7-3+12\\&=8 \end{aligned}

So, our remainder will be 8.
