Answer:18
Step-by-step explanation:
Step-by-step explanation:
When a point is reflected across the y-axis, the y-coordinate remains the same and the x-coordinate gets multiplied by -1.
(-4, -1) => (4, -1)
(2, 6) => (-2, 6)
The reflected points are (4, -1) and (-2, 6).
Answer:
4
Step-by-step explanation:
In the equation y=mx+b
b is the the value of y in the y-intercept
so change 2x+3y=12 into y=mx+b (Subtract 2x from both sides)
so 3y+2x-2x=12-2x
so 3y=-2x+12 (divide by 3)
y=-2/3x+4 so
(0,4) or
4
12 x 15 = 180
12 an hour for 15 hours
