Answer:
The length of the pool is 400 feet.
The width of the pool is 120 feet.
Step-by-step explanation:
We are given the width (W) is 30% of the length (L).
We are also given the perimeter of the pool is 1040.
So in equation form this is what we have:
W=.3L (of means multiply)
2L+2W=1040
We are going to plug the first equation into the second like so:
2L+2(.3L)=1040
2L+.6L=1040
2.6L=1040
Divide both sides by 2.6
L=1040/2.6
L=400
The length of the pool is 400 feet.
W=.3L
W=.3(400)
W=120
The width of the pool is 120 feet.
Answer:
Step-by-step explanation:
To graph the equation of line, we need to find the intercepts:
1) To find x-intercept: put y = 0
0 = -10x + 3000
Solving for x:
10x = 3000
x = 3000/10 = 300
A( 300, 0)
2) To find y intercept: put x = 0
y = -10(0) + 3000
y = 3000
B(0,3000)
Now plotting line through these two points gives the graph.
3) To find the slope of the equation:
Using two point form:


m = -10

Answer: 13
Step-by-step explanation: You count down 13 points and you plot the point of -15, 13 points to the left of -2.
