I hope this helps you
right angle 90

Y = 8x + 40.
Y = score, and x = hours of homework.
Substitute 3 into x
8 x 3 = 24
24 + 40 = 64
So the model predicts a score of 64 for 3 hours of homework.
Hope this helps.
G(x) = x² is the parent square function.
It has its vertex at origin and opens upwards.
The given graph is obtained by shifting the graph of x² 2 units vertically down. This vertically translation can be expressed by subtracting 2 from the parent function.
So,
F(x) = G(x) - 2
F(x) = x² - 2
Thus the correct option is A
Answer:
D
Step-by-step explanation:
3 1/2 - 1 7/10
7/2 - 17/10 (Common denominator 10, multiply 7 and 2 by 5)
35/2 - 17/10 = 18/10
1 8/10 = 1 4/5
Answer for the second question:
5*2 is 10
10 *2 is 20
20*2 is 40
40*2 is 80
80 *2 is 160
That's five hours
160*2 is 320
320*2 is 640
640*2 is 1280
1280*2 is 2560
The answer should be 2560
