Answer:
$74.50
Step-by-step explanation:
Using their given equation, y = 2.50x + 12, we can substitute 25 for x in order to solve it.
y = 2.50x + 12
y = 2.50(25) + 12
y = 62.50 + 12
y = 74.50
Therefore, Marty pays $74.50 for the total price if he rents 25 movies.
C is the answer if you add 2 to both numbers it will give you 12 and 10

Trying to factor a multi variable polynomial
2.1 Factoring kx - 2x2 - 7
Try to factor this multi-variable trinomial using trial and error
Factorization fails
Equation at the end of step

:
kx - 2x2 - 7 = 0
STEP
3
:
Solving a Single Variable Equation:
3.1 Solve kx-2x2-7 = 0
In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.
We shall not handle this type of equations at this time.
Use the first and lay set of x,y values.
Rate of change is change in y/ change in x:
7-10 / 5- -1 = -3/6 = -1/2
The answer is A.-1/2
Answer:
Step-by-step explanation:
Given sequence is: 4, 28, 196, 1372
28/4 = 7
196/28 = 7
1372/196 = 7
Since, the ratio of any two consecutive terms is same, so it is a geometric sequence.
Therefore,
Common ratio r = 7
First term a = 4
nth term of a geometric sequence is given as:
