Answer:

(x, y ) → (x - 6, y - 2 )

Step-by-step explanation:

Given

P(- 10, 1 ) → P'(- 16, - 1 )

Note that the x- coordinate of the image is 6 less than the original and

The y- coordinate of the image is 2 less than the original, thus

(x, y ) → (x - 6, y - 2 )

Given a polynomial f(x), if (x + 7) is a factor, what else must be true? Help plzzz im running out of time

solong [7]

Answer: f(-7) = 0
For the factored form of f(x), if x = -7, then one of the factors will be equal to 0, since (-7 + 7) = 0. This will cause the entire y-value to be 0, because anything multiplied by 0 = 0.

The shaded region in the graph represents the solutions of this system of linear inequalities:

kotegsom [21]

Answer:

$y$

$y\leq 2x+3$

Step-by-step explanation:

step 1

Find the equation of the solid line

From the graph take the points (0,3) and (4,11)

Find the slope

$m=(11-3)/(4-0)\\m=8/4=2$

The equation of the solid line in slope intercept form is equal to

$y=mx+b$

we have

$m=2$

$b=3$ ----> the y-intercept is the point (0,3)

substitute

$y=2x+3$

therefore

The inequality is

$y\leq 2x+3$

step 2

Find the equation of the dashed line

The slope is given

$m=4$

From the graph take the y-intercept (0,-5)

The equation of the solid line in slope intercept form is equal to

$y=mx+b$

we have

$m=4$

$b=-5$

substitute

$y=4x-5$

therefore

The inequality is

$y$

because the shaded region is below the dashed line

therefore

The system of inequalities is

$y$

$y\leq 2x+3$

What is the slope of the line that passed through (3,-4) and (4,9)

Advocard [28]

Step-by-step explanation:

<u>Step 1: Find the slope</u>

<u /> $m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{9-(-4)}{4-3}$

$m =\frac{9+4}{1}$

$m=13$

Answer: The slope is 13
