First do distributive property
2x + 10 + 3x = 30
Now combine like terms
5x + 10 = 30
Subtract 10 from both sides
5x = 20
Divide both sides by 5
x = 4
Answer:
y-intercept = (0,-21)
vertex = (2,-25)
Step-by-step explanation:
You need to expand the brackets eg.
(w-9)8 basically means 8 x (w-9) = 8w-72
Answer:
y = 22
Step-by-step explanation:
we want to move the -8 to the other side, so 14+8 = 22
y = 22
check: -8 + 22 = 14
