Answer:
Slope of the line y = x + 10 is 1. So, any straight line perpendicular to this must be having slope of (-1).
Let, the line be y = - x + b and it passes through (15, -5).
So, 15 = 5 + b
b = 10.
So, equation of that line: y = -x + 10
Or, x + y = 10.
Y-intercept of the line = 10 units.
Length = 2*width - 5
perimeter = 2(length + width)
89 = 2(2width - 5 + width)
89 = 6 width - 10
6 width = 99
width = 99/6 = 16.5 feet
length = 2*16.5 - 5 = 28 feet
Answer:
The jump rope cost $8.79 before the sale.
Step-by-step explanation:
She spent 15.08 on 2 while they were on sale. I divided 15.08 by 2 to find what each one cost individually on sale, which is $7.54. Then add $1.25 to $7.54= $8.79
You set both expressions equal to each other, then solve for x. Your answer will be x=12
Answer:
yes
Step-by-step explanation:
y <= -4x + 12
(2,4) 4 <= -4*2 + 12 4<= 4 is true
