Step-by-step explanation:
Given function is,
Where,
y = amount paid to the gym in dollars
x = number of months
So when x = 0, y =55(0)+80 = 80
i.e when number of months is 0, you have to pay a fee of $80.
This is the one time fee to open a membership.
After that for each month you have to pay $55 for each months.
So 55 is multiplied with x.
Answer:
Step-by-step explanation:
let, the length is z
thus the ratio will be 5z : 4z
perimeter = 2 (a + b)
360 = 2 ( 5z + 4z )
180 = 9z
z = 20 cm
length = 100 cm and width = 80cm
area = length * width
area = 100*80
area = 8000cm²

Answer:
2
Step-by-step explanation:
5x - 17
5(3) - 17 = 15 - 17 = -2
However, there is an absolute value sign over the expression. Abs value makes negatives turn positive. So -2 becomes 2.
1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is
, so in this case, it is
, which comes to
. Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y=
x-
.
2. Use the same process as in question 1 to find:
y=-7x+11
