As a computer technician, Andre makes $20 per hour to diagnose a problem and $25 per hour to fix a problem. He works fewer than

10 hours per week, but wants to make at least $200 per week. The inequalities 20x + 25y ≥ 200 and
x + y < 10 represent the situation. Which is true of the graph of the solution set? Check all that apply.

A-The line 20x + 25y ≥ 200 has a positive slope and a negative y-intercept.
B-The line x + y < 10 has a negative slope and a positive y-intercept.
C-The line representing 20x + 25y ≥ 200 is solid and the graph is shaded above the line.
D-The line representing x + y < 10 is dashed and the graph is shaded above the line.
E-The overlapping region contains the point (4, 5).

Solve for x: -5bracket(-3x+1)=-45
NikAS [45]

Answer:

Step-by-step explanation:

Equation

-5(-3x+1)=-45     If this is not correct, leave a comment please.

Solution

-5(-3x+1)=-45                     Divide by -5

-5(-3x + 1)/5 = -45/-5              

(-3x + 1) =  9                       Remove the brackets

-3x + 1 = 9                          Subtract 1 from both sides

-3x + 1 - 1 = 9 - 1                 Simplify

-3x = 8                               Divide by  -3

-3x/-3 = 8/-3

x = -8/3

or

x = -2.66

or

x = - 2 2/3
