The answer is -8. 3 x -3 = -9 + 1 = -8
Answer: y = 2
Step-by-step explanation:
we need to use systems of equations, basically since we know what x equals, we plug that into first equation so:
since x=2y+1,
we can say that:
(2y+1)+2y=9
then we solve this equation,
first we expand the brackets- 2y+1+2y=9,
then we combine like terms- 4y+1=9
then we take 1 away from both sides- 4y=8
then we divided both sides by 4
y=2

G(x) = 3x + 2(x + 1)
g(7) = 3(7) + 2(7 + 1)
g(7) = 21 + 2(8)
g(7) = 21 + 16
g(7) = 37
Correct me if im wrong, if you multiply 11.35 by 10 you get $113.5. multiply by 4 and that equals to $454.
