Answer:
x² -6x = -13
Step-by-step explanation:
Divide the equation by 8, the current value of "a".
... (8x² -48x)/8 = -104/8
... x² -6x = -13
49. 100-36= how many girls in percent
= 64%
64%= 16 girls
64/100=16/x
cross multiply
1600=64x
x=25
Y = 3/5x + b
3 = 3/5(-1) + b
3 = -3/5 + b, b = 3 3/5
Y = 3/5x + 3 3/5
I think the answer will be A
