I dunno I rlly don't know like seriously I'm in 7th
4 *3 = 12
12 * 20 = 240
240 / 2 = 120 units^3
answer is C
Answer:
X=0 and X=-2
Step-by-step explanation:
Move all terms to one side and set equal to 0. Then set each factor to 0 and solve.
X=0,-2
Answer:
The answer is: y = 3/8x + 28/8
Step-by-step explanation:
Given point: (4, 5)
Given slope m = 3/8
Uset the point slope form:
y - y1 = m(x - x1)
y - 5 = 3/8(x - 4)
y - 5 = 3/8x - 12/8
y = 3/8x - 12/8 + 5
y = 3/8x - 12/8 + 40/8
y = 3/8x + 28/8
Proof, use point (4, 5):
f(x) = 3/8x + 28/8
f(4) = 3/8(4) + 28/8
= 12/8 + 28/8
=40/8 = 5, giving (4, 5)
