Answer:
x = - 1
Step-by-step explanation:
Given
2 = 3x + 5 ( subtract 5 from both sides )
- 3 = 3x ( divide both sides by 3 )
- 1 = x
Answer:
So there are infinite solutions along the line y = 2x-1
Step-by-step explanation:
10x=5y+5
y=2x-1
Substitute y into the first equation
10x = 5(2x-1) +5
10x = 10x-5+5
10x = 10x
This is always true
So there are infinite solutions along the line y = 2x-1

well it is doubling every time. so 64$
Answer:
B
Step-by-step explanation:
f(x)= -3(x+1)^2 +2
> -3, Has to negative because its facing down
>(x+1) means it goes to the left 1 unit
> +2 at the end means it goes up by 2 units
