Good luck,!
If helped..mark brainliest please ;)
Step-by-step explanation:
Sample Response: Identify the dependent variable as either increasing, decreasing, or unchanged as the independent variable increases. It is possible to have no relationship shown on the graph.
Answer:
x=h/4−3y−1/2
Step-by-step explanation:
h=4(x+3y)+2
1) <u>Distribute</u> the 4 to x and 3y:
h=4x+12y+2
2) Subtract a 12y and a 2 from both sides:
4x=h-12y-2
3) Divide everything by 4:
x=h/4-3y-2/4
4) Simplify -2/4 to -1/2:
x=h/4−3y−1/2
as you already know, supplementary angles add up to 180°, therefore. if "x" is the supplementary angle, then
multiply second equation by 2 and rewrite
4a + 6b = 10
4a - 8b = 24
subtract equations
0 + 14b = -14
14b = -14
b = -1
sub back into 4a + 6b = 10 to find the value of a
4a + 6 (-1) = 10
4a - 6 = 10
4a = 16
a = 4
therefore, 12a = 12×4
