I forgot everything.
Did we even learn this?
Why is the alphabet involved?
2 + 2 = 6...right?
I quit.
100

Evaluate without using a calculator.

2+32×2-(1-2)

100

Find the sum.

(2x2+x-5)+(x2+x+6)

3x2+2x+1

100

Solve for x.

-10x+6x-30=12x-62

x=2

100

Solve for y.

2y+9<5y+15

y>-2

100

Solve for h.

A=12bh

h=2Ab

200

Determine whether the relation is a function. Explain.

(5,-2),(10,-4),(10,-6)

No. The relation is not a function because the input 10 has two outputs, -4 and -6.

200

The population of Hillville is currently 5,000 people. The population grows at an annual rate of 15%. Write an equation to describe this situation.

y=5000(1.15)t

400

Determine whether the table of values represents a linear, exponential, or quadratic function. Explain.

The table of values represents an exponential function because as x increases by 3, y is multiplied by 4.
