Evaluate the expression when:
x = 4 and y = -2

 $\frac{x^2+8}{4-y}$  

• x = 2

• 4

• 12

• all real numbers

Simplify,

 $3x-4\left(2x-3\right)-3$  

•  $-5x\ -15$  

•  $11x\ +9$  

•  $11x-15$  

•  $-5x+9$  

Translate the following verbal expression.

Four times the quantity of six less than a number.

• $4n-6$

• $4\left(n-6\right)$

• $4\left(6-n\right)$

• $\frac{4}{\left(n-6\right)}$

Find the solution.

 $2\left(4x-6\right)-4=6x+10$  

• x = 13

• x = 2

• x = -10

• x = - 4

Solve for k

 $h=fk-r$  

•  $k=h-fr$  

•  $k=\frac{h-r}{f}$  

•  $k=\frac{h+r}{f}$  

•  $k=f\left(h-r\right)$  

Choose the ordered pair that will make this relation a function.

 $\left\{\left(4,\ 2\right),\ \left(-8,\ 0\right),\ \left(3,\ -5\right),\ \ \ \ \ \ \ \ \ \ \ \ \ \ \right\}$  

• (-8, -4)

• (4, 1)

• (-5, 0)

• (3, -2)

Solve.

 $-4\left(3x-2\right)+4=10-12x$  

• x = 12

• x = 10

• infinite solutions

• no solution

Simplify:
3(9 + 2d) + 4d 

• 18d+10d
• 18d-10d
• 27+10d
• 37d

Solve for x:
x + 8 = -3

• x = -5
• x = 5
• x = -11
• x = 11

Solve for y: 
2y + 7 = 11

• y = 2
• y = 1
• y = 9
• y = 4
