The Jackson family rents 6 movies each month. Draw a graph of movies rented versus time. Find the value of the slope and interpr
atroni [7]

Let us say "y" coordinate represents number of movies and "x" coordinate represents number of months.

Movies watched in 1st month = 6

so we can say first ordered pair is (1,6)

Movies watched in 2nd month =6

so we can say second ordered pair is (2,6)

Now we have two points here (1,6) and (2,6)

We can use formula for slope as :

slope = \frac{y2-y1}{x2-x1}

slope = \frac{6-6}{2-1}

slope = 0

The slope of a horizontal line. A horizontal line has slope 0 because all its points have the same y-coordinate. As a result, the formula used for slope evaluates to 0.

The graph is shown here:

The equation of graph would be y=6.

A student deposits the same amount of money into her bank account each week. At the end of the second week she has $30 in her ac
Nonamiya [84]
The student will have $135 in her bank account at the end of the ninth week. You can fine this out by finding out the amount she deposits a week and to do this you would take the $30 and divide it by 2 because she had $30 at the end of the second week. 
30/2=15
So you see that the student deposits $15 each week, so to find out how much money she will have in 9 weeks you will multiply her $15 by 9.
15x9=135
So the student will have $135 at the end of the ninth week.

Explain the best you can because I’m struggling :)
Zigmanuir [339]

Step-by-step explanation:

A. 3x+4/2 = 9.5

3x + 4/2 = 9.5........criss cross

3x+4= 9.5×2

3x = 19-4

3x = 15

x=5 ..........divide both sides by 3

B. 7+ 2x/3= 5.......criss cross

7+2x = 5 × 3

7 + 2x = 15

2x = 15-7

2x = 8......divide both sides by 2

x = 4
