Answer:
y = -
x + 9
Step-by-step explanation:
0.5x + 0.6y = 5.4
0.6y = -0.5x + 5.4
Multiply 10 on all sides.
6y = -5x + 54
Divide 6 on all sides.
y = -
x + 9
Answer:
b
Step-by-step explanation:
Answer: D, -1
First, plug in the value -1 for x in f(x) first.

can then be simplified to

because

. Next, put the value -1 for x in the equation g(x). This will look like

.
The final step is to evaluate f(x) divided by g(x). f(x) = 1/2 and g(x) = -1/2, so when divided, you get -1.
G would equal 2 because 8g-4g=4g so the equation would really be
4g=8
Divide by 4 to equal 2
Answer:
y=1/2x
Step-by-step explanation:
m=1/2
y=mx+b
-1=1/2*-2+b
-1=-1+b
b=0
y=1/2x
