Answer:
5,6 and 9, 10 so E and F
Step-by-step explanation:
If it is question 9 of 1a
Since both are equivalent to y, the equations must be equivalent.
x^2-x-3= -3x+5
x^2+2x-8=0
(x+4)(x-2)=0
x=-4, x=2
Plug the values of x in to either equation
y=-3(-4)+5
y= 12+5
y=17
y= -3(2)+5
y=-6+5
y=-1
Final answer: (-4,17) and (2,-1)
F(x) = x/4
so
f(-8) = -8/4 = -2
answer
f(-8) = -2
Volume = length * width ( aka base ) * height
2 feet = 24 inches.
24*15*8=2880 inches.
