Step-by-step explanation:

There is no math problem

1 have no idea sorry

1) 2/5,42%,.45,5/11
2)-.65
3)17/19
4) Letter J
5) ? Can't see
6) Letter F
7) Letter C
8) ? Can't see all

2. Rate of change, or slope, is the change in y over change in x. Remember that a point is given in (x, y). Also that you need two points to find the change.
If you have two points, (x1, y1) and (x2, y2), the rate of change or slope would be 
[tex]\frac{y2-y1}{x2-x1}[/tex].

In your problem, the given points are (0, -1) and (2, -11).
Using the formula for rate of change, the rate of change would be:
[tex]\frac{-11+1}{2-0} = \frac{-10}{2}=-5[/tex].

The "initial value" is the y-intercept - where the graph intersects the y-axis and also where x = 0. The given point (0, -1) has x = 0, so the initial value is -1.

4. Remember the model equation for a graph of a line is
y = mx + b,
where m is slope and b is y-intercept - where the graph intersects the y-axis and also where x = 0.
The x-axis of the graph would be number of weeks, since it is independent.
The y-axis of the graph would be how much money she has.
Since she starts (at 0 weeks) at $25, the first point would be (0, 25). Notice here that it is the y-intercept since x = 0. The value of b in the model equation of a line y = mx + b would be 25.
The rate of change, or slope, is $5/week. This is m in the model equation of a line y = mx + b.
Putting b = 25 and m = 5 into the model equation y = mx + b (remember we use this equation because it works for all lines), the equation would be
y = 5x + 25.

4.
The slope of this will be -0.5degrees/hr, or just -0.5 if it is used as m in the 
y = mx+b equation. The slope is negative because it "decreases".

5. 
Plot each point and connect the dots. Remember the first number corresponds to the x-axis and the second to the y-axis.
For example in the table for x = -2 and y = -6, the point is (-2, -6), and from the origin (0,0) you go left 2 on the x-axis and down 6 to plot the point.

9.
I think you can do this if you can do #3, but now you have to find b by plugging in given values.
y = mx + b
y = 1212x + b

We can plug in the given point (3,1) to find b.
1 = 1212(3) + b
b = -3625

y = 1212 - 3625

10. Don't know which function you are referring to.

The slope is $10/week, or m = 10.
A point is (4, 90) because "After 4 weeks, Roberta has $90."
The y-intercept is 50 because x (weeks) = 0 at that time.

y = mx + b
y = 10x + 50

4 is the answer

Step-by-step explanation:

10+(-6)+(-6)+2+(-4)

10+(-6)= 10-6=    4

(-6)+2=6-2=       -4

                          8

                         -4

               4 is the answer

6 read the number on the left of the 11-15

 3.75 per shift

Step-by-step explanation:

Given : The amount earned by laundry = 12 dollars / hour

Since 1 dollar = 4 quarters.

Then, amount earned per hour=[tex]4\times12=48[/tex] quarters per hour.

    [By unitary method]

The time period for each shift = 75 minutes

Since 1 hour = 60 minutes

Then , 1 minute =[tex]\dfrac{1}{60}[/tex] hours     [By unitary method]

Now, 75 minutes =[tex]75\times\dfrac{1}{60}=1.25[/tex] hours

Now, the total amount earned from each shift will be:-

[tex]1.25\times48=60[/tex] quarters

Now , the cost of laundry= 12 quarters/load

The cost of load after increment = 16 quarters

Then, the number of loads can be washed :-

[tex]\dfrac{\text{Total amount earned from each shift}}{\text{Cost of load after increment}}\\\\=\dfrac{60}{16}=3.75[/tex]

Hence, number of loads of laundry = 3.75 per shift

(2,4)

Step-by-step explanation:

left( - ) and right( + ) (x axes)

up( + ) and down( - ) (y axes)

(5,2)  just add

5 - 3 = 2

2 + 2 = 4
