A) 5n6 + 8n5 - 3B) 10n11C) 5 + 8n6 - 3n5D) -7n6 + 8n5 + 9

2.Subtract.(8n7 + 2n6 + 17) - (5n6 + 5n7 + 15)

A) 3n7 - 3n6 + 32B) 3n7 + 7n6 + 32C) 2n13D) 3n7 - 3n6 + 2

3.Multiply.4(5x)

A) 20B) 20xC) 9xD) 9

4.Multiply.-8x2(-10x4 + 9x3)

A) 8x2B) 8x6 + 8x5C) 80x6 - 72x5D) 80x6 + 9x3

5.Factor.y2 - 64

A) (y + 64)(y - 64)B) (y + 8)(y - 8)C) (y2 + 8)(y2 - 8)D) (y - 8)(y - 8)

6.Solve and check the linear equation.9x - (7x - 1) = 2

A) B) C) D)

7.Solve and check the linear equation.6[-6x + 6 + 4(x + 1)] = 6x + 2

-36x + 36 + 24x + 24 = 6x + 2

-12x + 60 = 6x + 2

-6x = -58

x = =

A)  B) C)  D)  

8.Solve and check the linear equation.0.40x - 0.20(50 + x) = -0.04(50)

0.40x - 10 - 0.20x = - 2

0.20x = -2 + 10

x = 8/0.2

x = 40

A) {50}B) {30}C) {40}D) {20}

9.Solve the equation by factoring.x2 = x + 6

x2 - x - 6 = 0

x2 - 3x + 2x - 6 = 0

x(x - 3) + 2 (x - 3) = 0

( x-3) (x + 2) = 0

A) {-2, -3}B) {1, 6}C) {-2, 3}D) {2, 3}

10.Solve the equation by factoring.3x(x - 5) = 7x2 - 16x

3 x2 - 15x = 7 x2 - 16x

4 x2 = -15x + 16x

4 x2 = x

x(4x-1) = 0

A) B) {0}C) {0, 4}D)

11.Determine whether the relation is a function.{(-5, -4), (-2, 9), (-1, -2), (-1, 7)}

A) FunctionB) Not a function

12.Determine whether the equation defines y as a function of x.x + y = 9

y = 9 - x

A) y is a function of xB) y is not a function of x

13.Evaluate the function at the given value of the independent variable and simplify.f(x) = x2 - 1; f(x - 2)

(x - ...
