It would take about 25 months for the cost of leasing a billboard be the same for both companies.
<h3>
Linear function</h3>
A linear function is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let P represent the cost to lease a billboard from a different company for x months. Given that:
P(x) = 100x
For the second company, let C represent the cost, hence using the table point (1, 580) and (5, 900):
C - 580 = [(900 - 580)/(5 - 1)](x - 1)
C = 80x + 500
For the same cost:
100x = 80x + 500
x = 25 months
It would take about 25 months for the cost of leasing a billboard be the same for both companies.

Answer:
Step-by-step explanation:
The equation they are giving is:
Multiply both sides by 7 to get:
Subtract 4x from both sides to reach:
Therefore, .
Hope this helps :)
For this case we can have the following function:
r = f (t)
Where,
Independent variable is t.
Dependent variable is r.
To find the inverse we solve for the independent variable, that is, the data entry variable.
Answer:
FALSE
option B
X - 3y = -1
-x - 3y = 1
---------------add
6y = 0
y = 0
x - 3y = -1
x - 3(0) = -1
x = -1
one solution...and that is (-1,0)
