The temperature in degrees Celsius, c, can be converted to degrees Fahrenheit, f, using the equation f = StartFraction 9 Over 5 EndFraction c + 32. Which statement best describes if the relation (c, f) is a function?
It is a function because –40°C is paired with –40°F.
It is a function because every Celsius temperature is associated with only one Fahrenheit temperature.
It is not a function because 0°C is not paired with 0°F.
It is not a function because some Celsius temperatures cannot be associated with a Fahrenheit temperature.
Answer:
Step-by-step explanation:
B.It is a function because every Celsius temperature is associated with only one Fahrenheit temperature
Answer:
The correct answer is that it is a function because every Celsius temperature is associated with only one Fahrenheit temperature. so B!

1. Solve the following equation.(MAFS.8.EE.3.7)
5(3x + 7) + 2x = 7x – 5(–2x + 9)
Answer:
there is no solution
Step-by-step explanation:
Expand.
15x+35+2x=7x+10x-4515x+35+2x=7x+10x−45
2 Simplify 15x+35+2x15x+35+2x to 17x+3517x+35.
17x+35=7x+10x-4517x+35=7x+10x−45
3 Simplify 7x+10x-457x+10x−45 to 17x-4517x−45.
17x+35=17x-4517x+35=17x−45
4 Cancel 17x17x on both sides.
35=-4535=−45
5 Since 35=-4535=−45 is false, there is no solution.
No Solution
Answer:
Your answer is: No solution (There are no values of x that make the equation true.)

Answer:
no the first is -7 and the 2nd is 7
Answer:
No
Step-by-step explanation:
The absolute value makes anything in it positive. So I-7I is 7. But if there is a negative sign OUTSIDE of the absolute value, then it is negative.
-I-7I is -7
I-(-7)I is 7

TEN POINTS A QUESTION!!!
Answer:
What is the qestion
Step-by-step explanation:
Tucker was asked to solve the equation 5x + 3 = 6x + 1. He did not know if his first step should be to add 5 negative x-tiles, or 1 negative unit tile, to both sides. What advice would you give Tucker to help him decide on his first step? Explain.
Answer: First Subtract 5x from both sides. Then subtract 1 from both sides.
Step-by-step explanation: To solve an equation, get all the variables (x, in this example) on one side and all the constants (numbers alone) on the other side of the equation.
The thing to remember about solving an equation is to keep it balanced. Do the same thing on both sides.
When possible, subtract smaller numbers from higher numbers.
5x + 3 = 6x + 1
5x -5x + 3= 6x - 5x + 1
5x-5x =0 on the left side so they "cancel" On the right, 6x-5x = x
3 = x + 1
3 -1 = x +1 -1
On the right 1-1 = 0 So the 1's "cancel" On the left 3-1 = 2
2 = x Rewrite as x = 2 to tell the solution

Describe why alternate interior angles are not always congruent?
Answer:
The Alternate Interior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent .
Answer:
Alternate angles are always interior so in that case they will never meet up or join each other. hope this helps !

Explain the steps for dividing decimals. Write three or four sentences.
NO SAMPLE RESPONSE FROM EDGINUTY
Answer:
Step-by-step explanation:
Move the decimal point in the divisor and dividend.
Turn the divisor (the number you’re dividing by) into a whole number by moving the decimal point all the way to the right. At the same time, move the decimal point in the dividend (the number you’re dividing) the same number of places to the right.
Place a decimal point in the quotient (the answer) directly above where the decimal point now appears in the dividend.
Divide as usual, being careful to line up the quotient properly so that the decimal point falls into place.
Line up each digit in the quotient just over the last digit in the dividend used in that cycle.

A roofing company is repairing two houses. The first house needs 330.42 square yards of felt and the second house requires 286.48 square yards of felt. If both homes are 24% completed, how many square yards of felt has the roofing company used so far? (Round your answer to the nearest hundredth square yard.)
A 148.1 square yards
B 148.06square yards
C 147.94 square yards
D 147.96 square yards
Answer:
B. 148.06 square yards
Step-by-step explanation:
330.42 * 24% = 79.30
286.48 * 24% = 68.76
79.30 + 68.76 = 148.06

A spinner is divided into sections of equal size, of which some are red, some are blue, and the remaining are green. The probability of the arrow landing on a section colored red is 20%. The probability of the arrow landing on a section colored blue is 10%. What is the probability of the arrow landing on a section colored green?
Answer:
70%
What is given: 20% of one color, and 10% of another.
That gives us 30% of 100%.
Take away the smaller percentage from the limit, which would be 30 from 100.
You are left with 70%, which means that 20% is red, 10% is blue, and 70% is green.

Elliott is counting the change from a class fundraiser. He has half as many quarters as nickels, and he has 7 fewer dimes than nickels. The total value of coins is $5.90. He wrote the equation 0.10 (7 minus x) + 0.5 (x) + 0.25 (one-half x) = 5.90. Which statements identify Elliott’s errors? Check all that apply.
He should have written the expression for the number of dimes as x – 7.
He should have written the coin values as 5, 10, and 25 and not as 0.5, 0.10, and 0.25.
He should have written the coin value for the nickel as 0.05.
He should have translated the scenario as value of all dimes = value of all nickels and value of all quarters = value of all nickels.
He should have written the expression for number of nickels as 2x.
Answer: He should have translated the scenario as value of all dimes = value of all
