The number of people attending graduate school at a university may be modeled by the quadratic regression equation y = 10x2 - 40x+8, where x
represents the year. Based on the regression equation, which year is the best
prediction for when 2528 people will attend graduate school?
O A. Year 15
B. Year 23
O C. Year 18
D. Year 20

It’s C

Step-by-step explanation:

But thanks for helping me get it wrong toxo360❤️

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
