3. Each square on a grid represents 1 unit on each side. Match the numbers with the slopes of the lines.

A. 4

B. 1/4

C. -1/4

Step-by-step explanation:

The slope of each of these lines could be found by counting the rise over run. This means that you can count the change in y and divide it by the change in x. For example, the first line increase 4y and 1x. So, the slope is 4/1 or just 4.

However, there is another way to find the answer. If you understand the way slope affects a line, then you don't need to count the lines. Slopes that are greater than 1, like 4, will make a line steeper. The first graph has the steepest line; therefore, it must have a slope of 4. Fraction slopes will make the line less steep. The second 2 graphs are less steep, so they must be fractions. Finally, negative slopes will go in the opposite direction. The y-value will decrease as you go to the right instead of increasing like a positive slope. Therefore, graph 3 must have a slope of -1/4.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.
