### TRANSLATE EACH SENTENCE:

“5 times a number minus 4”

Three less than a number is 14

The sum of 4 times a number and negative 3

### Distance traveled d equals the product of the rate r and the time t. Given the rate and time traveled, find the distance traveled:

Rate = 15 miles per hour 2. Rate = 36 miles per hour

Time = 3 hours time = 1.5 hours

The numbers 1-6 were put into a coffee mug and pick out one at a time and then replaced after being picked. The table below shows how many times each number was picked.

How many times was

a number greater than 3 picked?

8

Which number was picked the most frequently?

2

If you lost the game every time you picked a number fewer than 5, how many times did you lose?

### Do the following percent problems:

1. What is 70% of 135 2. What percent is 48 of 96

m = -2/3

m = 1

### What is the y-intercept of the graph ofeachequation:

1. 3x – 6y = 12 2. x + 5y = -25

To find the y-intercept, you plug in ZERO FOR X

3(0) – 6y = 12

-6y = 12

-6 -6

y = -2

(0,-2)

(0) + 5y = -25

5y = -25

5 5

y = -5

(0,-5)

### Determine the slope of the line through points given:

1. (4,-8) and (3,6)2. (0,5) and (-3,-2)

### Graph each equation: 2x – 4y = 12 x + 3y = -9
