First: Slope of -x+2y=42y=x+4y=x/2+2So, m=1/2.
Second: Slope of the perpendicular line: mp=-2.
Third: Find the line with slope -2 and passes through the point (−2, 1)y-y1=m(x-x1)y-1=-2(x+2)y=-2x-4+1y=-2x-3

I think the question is asking for the cost (C) when we already know that the sell price (S) is $24
So C+M=S
C+0.45C=24
1.45C=24
C=16.5516
And the answer is $16 and 55 cents
Answer:
B
Step-by-step explanation:
7m+11= -4 x 2m + (-4 x 3)
7m +11 = -8m -12
7m +8m = -12-11
15m = -23
Answer:
x = 18; y = 20
Step-by-step explanation:
6.
Triangles KLM and KNO are similar, so the ratios of the lengths of corresponding sides are equal.
KL/KN = LM/NO
10/30 = 6/x
Cross multiply.
10x = 6 * 30
10x = 180
x = 18
KL + LN = KN
10 + y = 30
y = 20
Answer:
x=2
Step-by-step explanation:
x^3=8
x=2 (take the cubed root of both sides)
This can be solved by adding 8 to both sides, then taking the cubed root of both sides
