Answer: (-1,2) and (2,2) Make sure to see explanation!

Step-by-step explanation:

Well you need to remember the Y reflection rule!

To reflect over the Y axis you must do this:

Take the points in this case

(1,2) and (-2,2)

And you need to use the equation (x,y) --> (-x,y)

So the new points you NEED TO GRAPH ARE

(-1,2) and (2,2)

Hope this helped!

Answer: (-1,2) and (2,2)

Step-by-step explanation:

reflection over the y axis, take the point (x,y) and change the sign of the X-value (-x,y). When You reflect over the y-axis, the y remains the same.

point (1,2) would become (-1,2) reflected over the Y

and (-2,2) would become (2,2)

ANSWER CORRECTLY AND IF YOU DONT KNOW IT JUST DONT SAY ANYTHING

Answer:

A. 40, dollars added per day to the bank account

B. y -600 = 40(x -0); y = 40x +600; 40x -y = -600

C. f(x) = 40x +600

D. $880

Step-by-step explanation:

A. The slope is given by the formula ...

m = (y2 -y1)/(x2 -x1)

m = (720 -600)/(3 -0) = 120/3

m = 40

The bank account is increasing at the rate of $40 per day.

B. Point-slope form is ...

y -k = m(x -h) . . . . . line with slope m through point (h, k)

Using the first point, we have (h, k) = (0, 600) and m = 40.

y -600 = 40(x -0)

Slope-intercept form is ...

y = mx +b . . . . . . line with slope m and y-intercept b

The first point tells us the y-intercept is b=600, so the equation is ...

y = 40x +600

Standard form is ...

ax + by = c . . . . . . . a > 0, and a, b, c mutually prime

This form can be obtained by subtracting y from the point-slope form.

40x -y = -600

C. Replacing y with f(x) in the slope-intercept form gets the desired equation.

f(x) = 40x +600

D. The table shows the balance after 6 days. The balance increases $40 each day, so the balance after 7 days is ...

$840 +40 = $880 . . . . balance after 7 days

What is the equation of line l?

inessss [21]

Y=-3/2L -2. At the Y axis, line L is at -2, so we add that as B or the Y intercept. We can see that the graph goes 2 over to the right and down three, which makes the slope negative and 3/2 (rise/run)

What is the functions average rate of change over each interval?

telo118 [61]

we can use average rate of change formula

$\frac{f(b)-f(a)}{b-a}$

(a) x = -3 to x = -2

Firstly, we will find points

(-3, 0) and (-2,2)

now, we can plug these values into formula

and we get

$=\frac{2-0}{-2+3}$

$=2$

(b)x = -2 to x =1

Firstly, we will find points

(-2,2) and (1,-4)

now, we can plug these values into formula

and we get

$=\frac{-4-2}{1+2}$

$=-2$

(c) x = 0 to x =1

Firstly, we will find points

(0,-3) and (1,-4)

now, we can plug these values into formula

and we get

$=\frac{-4+3}{1-0}$

$=-1$

(d) x = 1 to x =2

Firstly, we will find points

(1,-4) and (2,0)

now, we can plug these values into formula

and we get

$=\frac{0+4}{2-1}$

$=4$

(e) x = -1 to x =0

Firstly, we will find points

(-1,0) and (0,-3)

now, we can plug these values into formula

and we get

$=\frac{-3-0}{0+1}$

$=-3$

(f) x = -1 to x =2

Firstly, we will find points

(-1,0) and (2,0)

now, we can plug these values into formula

and we get

$=\frac{0-0}{2+1}$

$=0$
