Pls answer i need answer fast
puteri [66]

Answer:

-24

Step-by-step explanation:

Given expression:

      3z (2y - 4)²

  z = -2 and y = 3

To solve this problem, simply substitute:

       3z (2y - 4)² = 3(-2){2(3) - 4}²

                           = -6(6-4)²

                           = -6 (2)²

                          = -6 x 4

                          = -24

zysi [14]

Answer:

About 3891 people saw that movie.

Step-by-step explanation:

Day 1: 985 people

Day 2: (985*8)/10 (20% gone) = 788

Day 3: (788*8)/10 (20% gone) = 630.4

Day 4: (630.4*8)/10 (20% gone) = 504.32

Day 5: (504.32*8)/10 (20% gone) = 403.456

Day 6: (403.456*8)/10 (20% gone) = 322.7648

Day 7: (322.7648*8)/10 (20% gone) = 258.21184

Adding this up:

985+788+630.4+504.32+403.456+322.7648+258.21184=

985+788+630+504+403+323+258=3891

Here's a graph of a linear function. Write the equation that describes that function. (Express it in slope-intercept form.)
rusak2 [61]

Answer:

y=\frac{1}{2}x+4

Step-by-step explanation:

The equation of a linear function in a slope-intercept form is written as

y=mx+q

where

m is the slope of the line

q is the y-intercept

We proceed as follows. First of all, we find the y-intercept, which is the value of y at which the line touches the y-axis.

From the graph, we see that this occurs at y = 4, therefore the y-intercept is

q=4

Now we have to find the slope. We do that by choosing two points along the line, with coordinates (x_1,y_1) and (x_2,y_2) and by using the equation

m=\frac{y_2-y_1}{x_2-x_1}

Here we take the two points:

(0,4)

(-8,0)

So the slope is

m=\frac{4-0}{0-(-8)}=\frac{1}{2}

Therefore, the equation of the line is

y=\frac{1}{2}x+4
