Answer:
366cm²
Step-by-step explanation:
Answer:
your question is really not clear but if you were to put the -4 in the Y then the answer would be X=1/3, if you plug in -4 for X and find Y then Y = -17
Step-by-step explanation:
plug in -4 in Y
-4=3x-5 add 5 on both sides,
1 = 3x divide 3 on both sides
1/3= x
plug in -4 in X
y = 3(-4)-5 multiply 3 and -4 = -12
y = -12-5 subtract the -12 and -5 = -17
y = -17
Answer:
y = -x + 8
Step-by-step explanation:
m = -1 ; x1 = 3 ; y1 = 5
Slope point form: y - y1 = m(x -x1)
y - 5 = -1(x - 3)
y - 5 = -1x - 3 *(-1)
y - 5 =-x + 3
y = -x + 3 + 5
y = -x + 8
Here, P = 2L + 2W, and L=W+55. Subbing W+55 for L in P = 2L + 2W, we get:
P = 2(W+55) + 2W = 270 in
2W + 110 + 2W = 270 in, or 4W = 160 in. Then W=40 in, and L=(40+55)in.
