Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 5 and the Trailing Constant is -32.
The factor(s) are:
of the Leading Coefficient : 1,5
of the Trailing Constant : 1 ,2 ,4 ,8 ,16 ,32
Let us test ....

180-160= 20
If you subtract 13 from my number and multiply the difference by -2 , the result is -44." What is 's number
Answer:
n = 35
Step-by-step explanation:
n - 13 x -2 = -44
distribute:
(n x -2) - (13 x -2) = -44
-2n - (-26) = -44
two negatives in front of a number makes it a positive number
so rewrite -2n + 26 = -44
-2n = -44 -26
-2n = -70
n = [tex]\frac{-70}{-2}[/tex]
n = 35
calc check (35 - 13) x -2 = 22 x (-2) = -44

Benito drew a graph representing the number of miles he ran and the number
calories he burned. What is the unit rate in calories per mile? 3 4 250 1,000
Answer:
250
Step-by-step explanation:
1000 divided by 4, is 250
The unit rate would be 250 calories per mile which is the slope of the given linear function.
What is the unit rate?The unit rate of a linear function is defined as the slope of the linear function.
The slope is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
The given graph represents the number of miles he ran and the number of calories burned.
Taking two points as per the given graph :(2, 500), (6, 1500)
Let
x₁ = 2, y₁ = 500
x₂ = 6, y₂ = 1500
Substitute values in the formula to get
unit rate = (1500 - 500)/(6 - 2)
unit rate = (1000)/(4)
Apply the division operation,
unit rate = 250
Therefore, the unit rate would be 250 calories per mile

Answer:
If your asking what the sum of the yards is it would be -1
Step-by-step explanation:
First I would make a number line from -10 to positive 10. Then from zero add nine. Then subtract 10 from 9. Since 10 is bigger than nine it would be a negative number. Hope this helped.

The number x is a two-digit number.
• When x is divided by 9, the remainder is 1.
• When x is divided by 10, the remainder is 3.
What is the remainder when x is divided by 11?
Be sure to explain how you got your answer.
Answer:
x = 73
x ÷ 11 = 73 ÷ 11 = 6.636 or [tex]6\frac{7}{11}[/tex] or ( 6 remainder 7)
Step-by-step explanation:
1. In order to determine the value of x, we will first find a two-digit multiple of 9 that has a unit value of (2)
Multiples of 9 = 18, 27, 36, 45, 54, 63, 72, 81, ...
from the above, the multiple of 9 that has a unit value of '2' is 72 ( 7 tens and 2 units)
2. Next, we will add 1 to the multiple of 9 found in step 1 above, to create a unit value of '3'. This is because when the number is divided by 9, we want to have a remainder of 1, and when the number is divided by 10, and we want to have a remainder of 3
72 + 1 = 73 ( 7 tens and 3 units)
3. Finally, let us divide the number in step 2 above by 10
73 ÷ 10 = 7 remainer 3.
Now the number 73 satisfies the three conditions given in the question:
1) The number x is a two-digit number.
73 is a two-digit number
2) When x is divided by 9, the remainder is 1.
73 ÷ 9 = 8 remainder 1
3) When x is divided by 10, the remainder is 3.
73 ÷ 10 = 7 remainder 3
∴ x = 73
x ÷ 11 = 73 ÷ 11 = 6.636 or ( 6 remainder 7)
Tristan and two of his friends purchased tickets to a school play. Tristan paid for all the tickets with a $50.00 bill and received $23.00 in change. If Tristan used a coupon for 25% off, what was the original price for one ticket?
Answer:
$36
Step-by-step explanation:
Tristan paid $50 for the tickets of the school play and was given $23 as change. The amount Tristan paid for the ticket is given as:
Price for ticket = amount paid - change = $50 - $23 = $27
Price for ticket = $27
Given that the ticket was sold at 25% off. Let x be the original price of the ticket, therefore:
x - 25% of x = $27
x - 0.25x = 27
0.75x = 27
x = 27/ 0.75
x = 36
Therefore the original price of the ticket is $36
Answer:
27.00

What is 859 divided by 3 with remainder
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
So all you have to do is use long division because a calculator won't help you with this if you are looking for a remainder so basically you just divide then you will get...

Answer:
x = − 4 \21
Step-by-step explanation:
Answer:
x= [tex]-\frac{4}{21}[/tex]
Step-by-step explanation:
Step 1- Distribute into the parenthesis.
(3)5x+(3)1-3x=2+(-3)3x+(-3)1
Step 2- Multiply.
15x+3-3x= 2-9x-3
Step 3- Add common variables.
(15x-3x)+3=(2-3)-9x
12x+3=-1-9x
Step 4- Add 9x to both sides.
12x+3= -1-9x
+9x +9x
21x+3= -1
Step 5- Subtract 3 to both sides.
21x+3= -1
-3 -3
21x= -4
Step 6- Divide both sides by 21.
21x= -4
21 21
