Lisa also cleans windows on the weekend. She charges $10 a window plus a $5 flat supply fee, regardless of the size of the window. Write the total charge, c, of a cleaning job as a function of the number of windows (w).

(A)
c = 10w + 5
(B)
c = 5w + 10
(C)
w = 10c + 5
(D)
w = 5c + 10

(A) c = 10w + 5

Step-by-step explanation:

Number of windows = w

Charge = c

The $10 value is a dependent value in which it depends on how many windows cleaned.

So: 10w

$5 in the other hand, is independent.

So: + 5

Putting it altogether,

c = 10w + 5

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

okay..i will pick 8!
