Y=− 2 x + 7 ; y = 5 x − 7
1 answer:
Do you need to solve for x? As the both equal y, they must both equal each other so -2x+7=5x-7 Add 2x to both sides 7=7x-7 Add 7 to both sides 14=7x Divide both sides by 7 2=x X=2

C and D are the right answers
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
First find h(3)
2(3)-2= 4
then find g(4)
4³-5= 59
<span>4w^3−8w+12 = 4 (w^3 - 2w + 3) </span><span>5t^2+20t+50 = 5 (t^2 + 4t + 10)</span>
∛(1/8 - <em>x</em>) = -1/2
Take the 3rd power of both sides and solve:
(∛(1/8 - <em>x</em>))³ = (-1/2)³
1/8 - <em>x</em> = -1/8
2/8 = <em>x</em>
<em>x</em> = 1/4
Say base1 = 26 and base2 = 12 then your height is 18.
1/2 (18) times ( 26+12)
So that's 9 times 38=342
342 squared is your answer
