A. C = 17h + 15
b. 83 = 17h + 15 
    -15           - 15  subtract 15 from both sides 
    68 = 17h
    ------------
         17               divide both sides by 17
      4=h  
  They cleaned the house for 4 hours
c. C = 20x
to do this last part, you would put both equations into the calculator under y=, then look at the table to determine when the price is the same. According to the calculator, the price is the same at 5 hours

Answer:

Solving the inequality 3x -2 < 4 we get \mathbf{x

Option D is correct option.

Step-by-step explanation:

We need to solve the inequality 3x -2 < 4 and find value of x

Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.

3x -2 < 4

Adding 2 on both sides

3x -2+2 < 4+2\\3x < 6

Now, we will divide 3 on both sides

\frac{3x}{3}

So, we get x < 2

Solving the inequality 3x -2 < 4 we get \mathbf{x

Option D is correct option.

Consider the equation x+4=−2x+19. Let f(x)=x+4and g(x)=−2x+19. The graph of each function is shown. Coordinate plane with the gr
Svetach [21]

The point of intersection of both graphs will have the coordinate (5, 9).

<h3>What is the Point of Intersection of the Graph?</h3>

We are given the functions;

f(x) = x + 4

g(x) = -2x + 19

Now, the point of intersection of both graphs is when both functions are equal which is at f(x) = g(x). Thus;

x + 4 = -2x + 19

x + 2x = 19 - 4

3x = 15

x = 15/3

x = 5

Thus;

f(x) = 5 + 4 = 9

g(x) = -2(5) + 19 = 9

Thus, the point of intersection of both graphs will have the coordinate (5, 9)
