Grace [21]

Answer:

C

Step-by-step explanation:

The line on the left has equation y = x - 2

The start of the line has an open circle at x = 3 meaning that x ≠ 3

The line is defined as y = x - 2 for x < 3

The line on the right has equation y = x - 1

The start of the line has a closed circle at x = 3 meaning that x can equal 3

The line is defined as y = x - 1 for x ≥ 3

Thus the definition of the function is C

Jason had $32. He spent all the money on buying 4 CDs for $x each and 2 magazines for $y each. If Jason would have bought 5 CDs
larisa86 [58]
. The student's conclusion is incorrect because the solution to the system of equations 4x + 2y = 32 and 5x + 2y = 36 is (4, 8).
B is right option
4x + 2y = 32
5x + 2y = 36 subtracting
-x=-4
x=4
4(4)+2y=32
16+2y=32
2y=16
y=8
hope this helps
