f(x) − g(x) = 7x^2 - 13x
Answer: c = -7
Step-by-step explanation:
-4 + c = -11
c = -7
Answer:
10x + 5y = 11
Step-by-step explanation:
I usually find it in slope intercept then convert, it's easier for me.
First you find slope using delta y over delta x giving you -2/5.
so you have y=-2/5x + b
To find b plug in a point and solve down
1 = -2/5(3) +b
1+6/5 = b
b = 11/5
y=-2/5x + 11/5
Then you convert it to Ax+by=C form,
multiply by 5
5y = -10x + 11
move x
10x +5y = 11
P = 2(L + W)
P = 264
W = 54
264 = 2(L + 54)
264 = 2L + 108
264 - 108 = 2L
156 = 2L
156/2 = L
