Answer:

72 and -2

Step-by-step explanation:

x - y = 74

2x + 3y = 138

x - y = 74

y = x - 74

2x + 3(x - 74) = 138

2x + 3x - 222 = 138

5x = 360

x = 72

x - y = 74

72 - y = 74

-y = 2

y = -2

PilotLPTM [1.2K]

Answer:

  • Option A or first option

Step-by-step explanation:

The function is

f(x) = \left \{ {{-1.5x + 3.5, x

Correct description is the first option with the exception of point (2,0), it should read (2, 0.5)

  • On a coordinate plane, a piecewise function has 2 lines. The first line has an open circle at (2, 0) and then goes up through (1, 2) with an arrow instead of an endpoint. The second line has a closed circle at (2, 6) and goes up through (3, 7) with an arrow instead of an endpoint.

The graph is attached

4(x-2)-3=9 I have to solve for X but I'm confused
ExtremeBDS [4]
You distribute the 4 to the x and the -2. So the left side of the equation would look like 4x-8-3=9. Add 3 to both sides to get 4x-8=12. Add 8 to both sides and get 4x=20. Divide both sides by 4 and x =5
