Another term to represent Unit Rate is?
Constant of Proportionality
Slope
Rate of Change All of the Above
None of the Above
Answer:
All of the above.
Step-by-step explanation:
In a graph, the unit rate gives us the change in y for a unit change in x. That is, the unit rate is the rate of change in y when the change in x is 1.
Therefore, the unit rate is the same as the rate of change.
And the rate of change is synonymous with the slope.
The constant of proportionality is simply the slope/rate of change for proportional equations.
Therefore, the constant of proportionality is also another word for the unit rate.
Our answer is hence all of the above.

19 points Solve for c. 5/4c+12=2
Answer:
C= -8
Step-by-step explanation:
I used a calculator
Answer:
c=-8
Step-by-step explanation:
[tex]\frac{5}{4}c[/tex] + 12 = 2
1.25c + 12 = 2 ( change 5/4 to a decimal for easy understading)
1.25c + 12 - 12 = 2 - 12 ( isolate the variable rememebr whatever you do to the right do it to the left )
1.25c = -10
1.25c / 1.25 = -10 / 1.25 (divide both sides by 1.25 )
c = -8

Answer:
x=20-y
y=20-x
Step-by-step explanation:
divide by 2 on both sides: x+y=20
to find x, subtract y:
x=20-y
to find y, subtract x:
y=20-x
nothing else can be done unless you know either y or x.
Turn this into numerical form -> one-half the sum of x and 12
Answer: 1/2(x+12)
