Alandscaper charges a one-time fee of $70 plus $45 for each hour on the job. if t is the number of hours on the job and f is the total fee for the work done, then the variables are related by the equation f = 45t + 70. which variable is the independent variable?

a. t b. f c. there is no relationship between the variables.

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
