I would say direct because the more gallons of gasoline used, the bigger the cost.
Answer:
-5.6
Step-by-step explanation:
g(x)=2x-1
g(-2.3)=2(-2.3)-1=-4.6-1=-5.6
Y=ax+b
3=-8(0)+b
3=0+b
3=b
Y=-8x+3
(I think this is right, but u might want to double check)
Answer:
x = 3
y = -1
Step-by-step explanation:
Finding X
Substitute y into the 1st equation
3x + 2(x-8) = 7
Simplify
3x + 2x-8 = 7
Combine like terms
5x - 8 = 7
Move the constant (-8) to the right
5x = 7+ 8
Simplify
5x = 15
Divide both sides by 5
x = 3
Finding Y
Now since you know x is 3 substitute that into the 2nd equation
y = 3 - 4
y = -1
