<span>-x + 5y= -18 so x = 5y + 18
5x-9y=10
substitute </span>x = 5y + 18 into 5x - 9y = 10
5x - 9y = 10
5(5y + 18) - 9y = 10
25y + 90 - 9y = 10
16y = - 80
y = -5
x = 5y + 18
x = 5(-5) + 18
x = -25 + 18
x = -7
answer
(-7, -5)
Answer:
The surface area is 13.08 and the volume is 3.14
Step-by-step explanation:
The point-slope form of a line is:
y-y1=m(x-x1), where m is the slope of the line and (x1,y1) is any point on the line.
In this case x1=7 and y1=-2 so the point used to create this equation is:
(7, -2)
Diameter goes across the whole circle, and Radius is halfway
