Answer:
A constant in math is a value that doesn't change. Instead, it's a fixed value. All numbers are considered constant terms.
Answer:
No, it is not.
Step-by-step explanation:
This is because if you look at the expression, there is no term that is raised to the cube root. As a result, this isn't a cubic polynomial. However, this would be a quadratic polynomial cause the highest raised exponent is 2, which is the number for quadratic.

Take 11 gallons out of 28 and put 4 more gallons in 13
7v = 2v - 20
First, subtract 2v from both sides. / Your problem should look like: 7v - 2v = -20
Second, simplify 7v - 2v to 5v. / Your problem should look like: 5v = -20
Third, divide both sides by 5. / Your problem should look like: v =
Fourth, simplify

to 4. / Your problem should look like: v = -4
Answer:
v = -4
Answer:


Step-by-step explanation:
Solve the following equation:
-In order to solve a pair of equations by using substitution, you first need to solve one of the equations for one of variables and then you would substitute the result for that variable in the other equation:
-First equation:

-Second equation:

-Choose one of the two following equations, which I choose the first one, then you solve for
by isolating

-Subtract
to both sides:

-Subtract
to both sides:


-Divide both sides by
:


-Multiply
by
:


-Substitute
for
in the second equation, which is
:


Multiply
by
:


-Combine like terms:


-Subtract
to both sides:


-Multiply both sides by
:


-After you have the value of
, substitute for
onto this equation, which is
:


-Multiply
and
:


-Since both
and
have the same denominator, then add the numerators together. Also, after you have added both numerators together, reduce the fraction to the lowest term:
