8x + 4y= 16 for y

• y = -8x + 16
• y = 2x -4
• y = -2x + 4
• y = -8x + 12

M= i + r ; solve for r

• M-i
• M+i
• -M-r
• -M+i

Solve the literal equation for the given variable.

• 2A/h
• 2/(h)
• 2Ah
• Ah/2

Solve for h,      S =  $2\pi rh$  

• h=  $\frac{S}{2\pi r}$  

• h =  $S2\pi r$  

• h =  $S-2\pi r$  

• h =  $\frac{2\pi r}{S}$  

Solve for x

y = mx + b

• $x=\frac{yb}{m}$

• $x=ybm$

• $x=\frac{y+b}{m}$

• $x=\frac{y-b}{m}$

 $p\ =\ 2l\ +\ 2w$  
solve for w

•  $w=\frac{p}{2l}-2$  

•  $w=\frac{p-2l}{2}$  

•  $w=\frac{p+2l}{2}$  

•  $w=2p-l$  

 $V=\frac{1}{3}Bh$  
Solve for h

•  $h=\frac{1}{3}V-B$  

•  $h=\frac{\frac{1}{3}V}{B}$  

•  $h=3V-B$  

•  $h=\frac{3V}{B}$  

 $V=\frac{4}{3}\pi r^3$  
Solve for  $r^3$  

•  $r^3=\frac{4\pi}{3V}$  

•  $r^3=\frac{3\pi}{4V}$  

•  $r^3=\frac{3V}{4\pi}$  

Given that the slope is  2/3 and the y intercept is -3 what is the equation of the line?

• y = 2/3x - 3
• y = 2/3x + 3
• y = -2/3x - 3
• y = -2/3x + 3

Given that the slope is  -4 and the y intercept is -4 what is the equation of the line?

• y = 4x - 4
• y = -4x - 4
• y = -4
• y = -4x + 4
