You change the Y sign.
L = 1, -2
Q = 4, 1
G = 3, -4
B is the correct answer. The $20 flat fee is the 20 in the equation. The 4 dollars per hour is the 4h in the equation. The $30 is the total amount at the end of the equation.
You should be able to find the maximum value of c by simply substituting the maximum values for x and y.
So we'll let x = -2 and y = 6.
The equation is is now as follows:
c = 5(-2) + 4(6)
c = -10 + 24
c = 14
Therefore the maximum value for c is 14.
Answer:
20%
Step-by-step explanation:
To find the percent decrease, we do old number subtracted from the new numbers over old.
We do
40 - 32 = 8
Then we put the 8 over the old and get
