Okay first you need to do distribute the -3 to remove the parentheses:
y - 4 = -3x + 9
Then you need to move -4 to the right by adding on both sides
y = -3x + 9 + 4
The answer is —> y = -3x + 13
Let's call the Ameri-Mobile activation fee A, and the Cell-U-Later activation fee B.
Let's call the Ameri-Mobile monthly payment c, and the monthly Cell-U-Later monthly payment d
Let's call n the number of months
The cost of the Ameri-Mobile (in business, that's often called "total cost of ownership) is then:
(a + c * n)
<em>The cost of the plan after n months is the activation fee, plus each monthly payment times the number of months paid</em>
The cost of Cell-U-Later is, similarly:
(b + d * n)
You can even find out how many months you'd need to keep the plan for each plan to be equal (the longer you keep the plan, the better is the Cell-U-Later plan, because the activation fee distributes across a higher number of months), by plugging in numbers and solving this equation for n (but that's a bit more advanced):
a + c*n = b + d* n

Answer:
Step-by-step explanation:
Linear Equations do not have the value of x squared. They also shouldn't have the x value taken by the square root.
The second and third equations would be graphed as non-linear functions.
Answer:
The number is 10
Step-by-step explanation:
Let x be the number
product is multiply
12 + (2x) = 4x -8
Subtract 2x from each side
12+2x-2x = 4x-2x-8
12 = 2x-8
Add 8 to each side
12+8 = 2x-8+8
20 = 2x
Divide by 2
20/2 = 2x/2
10 =x
