Answer: b = 2a
Step-by-step explanation:
<u>Original equation</u>
a = (1/2) b
<u>Multiply 2 on both sides</u>
a * 2 = (1/2) b * 2
Hope this helps!! :)

Answer:
The inverse is x/3 -1
Step-by-step explanation:
y = 3x+3
To find the inverse, exchange x and y
x = 3y+3
Solve for y
x-3 =3y+3-3
x-3 = 3y
Divide by 3
x/3 - 3/3 = 3y/3
x/3 -1 = y
The inverse is x/3 -1
1) 4x
2) 2x+3z=5z
=5z+5
3) I can't see problem number 3.
4) 9g+8g=17g
5) 5p-p=4p
=4p-8
6) Cant see problem number 6.
7) 4x-x= 3x 3y+2y
=3x+5y
8) 5x+4x= 9x 2y-y=y
=9x+y
9) Can't see problem number 9.
10) 7p+2p=9p 5z-2z=3z
=9p+3z
11) 7g+5h-12
12) Can't see problem number 12.
13) 3(r+2)-2r
3r+6-2r
=r+6
14) 5(2+x)+3x
10+5x+3x
=10+8x
15) Can't see problem number 15.
Answer:

Step-by-step explanation:
< or > will give you an open dot which means it is not filled in.
≤ or ≥ will give you a closed dot which means it is filled in.
So for example number one:
x > 0 translated is x is greater than zero.
So look on the number line for an open dot on zero going toward the left (the side where the numbers get smaller). The rest are self explanatory.
