Answer:
Do you have any key words from the unit?
Step-by-step explanation:
1.)x+5;x=3
(3) + 5
8
2.)7x;x=-5
7(-5)
35
3.)y=1-2x;x=9
y = 1 - 2(9)
y = 1 - 18
y = -17
4.)y=3x+2;x=0.5
y = 3(0.5) + 2
y = 1.5 + 2
y = 3.5
5.)y=2x^3;x=3
y = 2(3^3)
y = 2(3)(3)(3)
y = 2(27)
y = 54
<span>6.)y=x/2+9;x=-12
y = (-12)/2 + 9
y = -6 + 9
y = -3</span>
One way to solve the system of equations would be to solve for q (in terms of r) in the first equation to get:
9r + q = 13
q = 13 - 9r
Then, take the value for q you just found and insert it into the second equation:
3r + 2(13-9r) = -4
Then simplify and solve:
3r + 26 - 18r = -4
-15r = -30
r = 2
Now that you have the value for r, plug it into either of the original equations and solve for q:
9r + q = 13
9(2) + q =13
18 + q = 13
q = -5
r = 2; q = -5
