Answer:
-8
Step-by-step explanation:
If 3x-4y=2, then for any number a we also have a(3x-4y)=a(2) by multiplication property of equality.
Therefore, for a=-4 we have -4(3x-4y)=-4(2) which means the value of -4(3x-4y) is -8.
Answer:
Laney gets pounds of fudge.
Step-by-step explanation:
2 3/5 x 1/3
A = 13.95 ft^2
l = x
b = x + 1.4
a = l × b
13.95 = x × ( x + 1.4 )
13.95 = 3.1 × ( 3.1 + 1.4 )
13.95 = 13.95
length = 3.1
width = 4.5

Answer:
a= -1 b=4 c = 5 y-int = -1, 5 x-int = 5
Step-by-step explanation:
In order to find a, b, and c you just look at the coefficients for the first second and third term in the equation. To find the y-intercepts you need to factor the equation down to (-x +5)(x + 1) then set both of those new equations equal to zero and solve. Lastly, to get the x-int just fill in 0 for every x in the problem and then simplify.
