Answer:8 or 9 ft
Step-by-step explanation:
Given
The area of the pool is [tex]A=x^2-17x+72[/tex]
The area is in the form of a quadratic equation
So, the roots of the equation will give the length and width of the pool
[tex]\Rightarrow x^2-17x+72=0\\\Rightarrow x^2-8x-9x+72=0\\\Rightarrow x(x-8)-9(x-8)=\\\Rightarrow (x-8)(x-9)=0\\\Rightarrow x=8\ or\ 9[/tex]
Therefore length and width can either be [tex]\text{8 or 9 ft}[/tex].
[tex]\Rightarrow L=8\ ft,W=9\ ft\ \text{or}\ L=9\ ft,W=8\ ft[/tex]

-4x + 2y = -20
a. none of the above
b. infinitely many solutions
c. no solution
d. one solution
Answer:
c. no solution
Step-by-step explanation:
This system of equations has no solution because when graphed, the lines are parallel to each other. Meaning they will never intersect. Since they will never intersect, there are no solutions.

Answer:
17.5
Step-by-step explanation:
Answer:
17.5
Step-by-step explanation:
Using Pythagoras theorem
X² = 15² + 9²
X² = 225 + 81
X² = 306
Take the square root of both sides
X = √306
X = 17.5

Coach Rivas can spend up to $750 on 30 swimsuits for the swim team. The inequality shown can be used to find the maximum amount in dollars she can spend on each swimsuit. 30p≤750 which inequality represents all the possible values of p,the amount of money in dollars coach Rivas can spend on each swimsuit
Answer:
$0 < p ≤ $25
Step-by-step explanation:
We know that coach Rivas can spend up to $750 on 30 swimsuits.
This means that the maximum cost that the coach can afford to pay is $750, then if the cost for the 30 swimsuits is C, we have the inequality:
C ≤ $750
Now, if each swimsuit costs p, then 30 of them costs 30 times p, then the cost of the swimsuits is:
C = 30*p
Then we have the inequality:
30*p ≤ $750.
To find the possible values of p, we just need to isolate p in one side of the inequality.
So we can divide both sides by 30 to get:
(30*p)/30 ≤ $750/30
p ≤ $25
And we also should add the restriction:
$0 < p ≤ $25
Because a swimsuit can not cost 0 dollars or less than that.
Then the inequality that represents the possible values of p is:
$0 < p ≤ $25
what’s the slope for this graph ??
Answer:
M = 0
Step-by-step explanation:
Straight line is always slope of 0
Answer:
Step-by-step explanation:
Slope is defined as
m=(y2-y1)/(x2-x1) in this case
m=(5-5)/(5- -5)
m=0/10
m=0
This is a horizontal line, y=5, with a slope of zero.

Which equation could be solved using this application of the quadratic formula?
Answer:
Step-by-step explanation:
A.) x² + 1 = 2x − 3 Make the equation into ax² + bx + c = 0. Subtract 2x on both sides, and add 3 on both sides to set the equation equal to 0
x² + 1 - 2x + 3 = 2x - 2x - 3 + 3
x² - 2x + 4 = 0
a = 1
b = -2
c = 4 This is not the answer because b = 2 not -2, and c = -4 not 4
B.) x² - 2x − 1 = 3 Subtract 3 on both sides to set the equation = 0
x² - 2x - 4 = 0
a = 1
b = -2
c = -4 This is not the answer because b = 2 not -2
C. x² + 2x - 1 = 3 Subtract 3 on both sides to set the equation = 0
x² + 2x - 4 = 0
a = 1
b = 2
c = -4 This is your answer
D. x² + 2x - 1 = -3 Add 3 on both sides to set the equation = 0
x² + 2x + 2 = 0
a = 1
b = 2
c = 2 This is not the answer because c = -4 not 2

A town low temperature for January was -8 Fahrenheit. The difference between The town high temperature and low temperature for January was 25. What was the town high temperature .In degrees Fahrenheit ,for January
Answer: 17°F
Step-by-step explanation:
Let the the town high temperature .In degrees Fahrenheit ,for January be represented by x
Since the town had low temperature for January was -8 Fahrenheit and the difference between the town high temperature and low temperature for January was 25. Then, the high temperature will be:
x - (-8) = 25
x + 8 = 25
x = 25 - 8
x = 17°F

8 and 10 can both be divided by 2. So, 8 ÷ 2 is 4 and 10 ÷ 2 is 5.
Hope this helps :)
Answer:
4/5
Step-by-step explanation:
okay so to simplify, we first need to find the GCF of 8 and 10. The GCF of 8 and 10 would be 2. We now divide both 8 and 10 by 2. That will give us 4/5.
[tex]\frac{8}{10}[/tex]÷[tex]\frac{2}{2}[/tex]=[tex]\frac{4}{5}[/tex]

A tank contains 550 gallons of water. When the valve is opened, the tank drains at a rate of 12 gallons per minute. Which function shows the relationship between the time t the valve is opened and the amount of water in the tank?
Answer:
y= 550-12x
Step-by-step explanation:
Given data
Content of tank= 550 gallons
Rate of drain= 12gallon per minute
let the time it will take to drain all 550 gallons be x minutes
Hence the expression for amount of water in the tank after x minutes will be
y= 550-12x
