Answer:
1. 8x + 2y = 16
Step-by-step explanation:
3x - 12y = 10
12y = 3x - 10
y = 1/4 x - 5/6 .... slope: 1/4
perpendicular line slope: -4
8x + 2y= 16
2y = -8x + 16
y = -4x + 8 .... slope: -4
Answer: D: x = {-3, -1, 1}
<u>Step-by-step explanation:</u>
Domain refers to the x-values of the coordinates.
Coordinates are in the form (x, y) so we are looking for the values on the left side of the parenthesis.
(-3, -2) --> x = -3
(-3, 0) --> x = -3 <em>already listed above so no need to list it again</em>
(-1, 2) --> x = -1
(1, 2) --> x = 1
the x-values are: -3, -1, & 1
so the domain is: x = {-3, -1, 1}
Is the = -13. Is the response
She practices 5 hours a day.
120/4 = 30 hours per week.
30/6 = 5 hours per day.
