Write a function rule for the table.
OC= 220 + 12
Oc= 220
Oc= 220 + 22
O c = 120 + 22
Answer:
c = 22o + 12
Step-by-step explanation:
As input values increase by 1, output values increase by 56-34=22. The output value for o=1 is 12 more than 22o, so the function rule seems to be
c = 22o +12
__
Based on answer choices, we assume that input is o, and output is c. '0' is not a variable.

Answer:
Robert is 10 and his dad is 40 years old
Step-by-step explanation:
We have (4x+5)=3(x+5)
4x+5=3x+15
x=10.
Roberts is 10 years old and his father is 40 years old.
Answer:
Step-by-step explanation:
Roberts's father=4x
Robert=x
After 5 years, the ages will be
4x+5 and x+5 because we just simply add 5 years to their ages
It says that the father will be 3x older. So,
3(x+5)=4x+5. --this is the equation
3x+15=4x+5
-5 -5
3x+10=4x
-3x -3x
x=10

a car rental company charges $30 per day to rent a car plus $0.02 per mile driven. which equation represents c, the total cost to rent a car for 5 days, when m is the total number of miles driven?
Answer:
c=0.02(m)+30(5)
or
c= 150+0.02(m)
or
c=0.02(m)+150
or
c=30(5)+0.02(m)
Step-by-step explanation:
This is because c, or cost is equal to 30 dollars a day as a base fee or 150 total for five days plus 0.02 per mile. So, if you multiple the mileage driven by 0.02 and add 150 for the 30$ per day at 5 days. This is your equation
These are just different ways you could write that since it is clear you have a multiple choice question

Forty-five is six more than three times a number.
Answer:
13
Step-by-step explanation:
45 - 6 = 39/3 = 13
Answer:
Forty-five is six more than three times 13.
Step-by-step explanation:
First, you have to set up the equation. We know 45 equals three times a number, 3x, plus 6.
45 = 3x + 6
Subtract 6 from both sides.
39 = 3x
Divide by 3 to isolate the x, and you get 13. Hope that helps!

A biologist measured the length and mass of 20 reptiles. the equation
y = 0.3x - 2 is the line of the best fit for data, where x is the length, in centimeters, and y is the mass in grams.
Based on the equation, what is the approximate length of a reptile that has a mass of 20.5 grams?
a. 62 cm
b. 66 cm
c. 70 cm
d. 75 cm
Please answer quickly!!
D. 75 cm
Step-by-step explanation:
fill in the y with 20.5, so you get 20.5=0.3x-2. Add the 2 to the 20.5 so you get 22.5=0.3x. Divide both by 0.3 to get 75=x.

1) If 2x + 3y = 12 and xy = 6, find the value of 4x2 +9y2.
Answer:
72
Step-by-step explanation:
Given that 2x + 3y = 12 , then
(2x + 3y)² = 12² = 144 ← distribute left side using FOIL
4x² + 12xy + 9y² = 144 ( subtract 12xy from both sides )
4x² + 9y² = 144 - 12xy = 144 - 12(6) = 144 - 72 = 72
