Answer:
y - 3 = - 4 ( x + 4)
Step-by-step explanation:
(-4,-3) and (4,1)
Slope = (1 + 3)/(4 + 4) = 2/8 = 1/4
Perpendicular lines, slope is opposite and reciprocal so slope of the line that is perpendicular to the given line is -4
Equation in point slope form, passing thru (-4 , 3)
y - 3 = - 4 ( x + 4)
<span>a) define the variables
The variables are x and y ; x can represent the number of times Aleah goes swimming ; while y can represents the number of times Aleah goes skating.
b) are there any restrictions on the variables?
The total sum of both activities must be equal or less than $80 a month
c) write a linear inequality to represent this situation
</span><span>Swimming costs $5 each time and skating costs $4 each time. No more than $80 a month.
5x + 4y <u><</u> 80
You can graph linear inequality using these coordinates.
x y
16 0
12 5
8 10
4 15
0 20</span>

Answer:
<h2>The height of cylinder = 7 inches</h2>
Step-by-step explanation:
The formula of a volume of a cylinder:
r - radius
H - height
We have
r = 5 in
V = 175π in³
Substitute:
