For this problem you need to understand that a linear graph is a straight line (Remember Rise/Run). 
A continous function is <span>a </span>continuous function<span> is a </span>function <span>for which sufficiently small changes in the input result in arbitrarily small changes in the output, so we can already cross off that as an answer.
The Y-Intercept is the cost (in dollars), so this would be to monthly fee. 
Now, onto the rate of change. T</span>he rate of change is <span>represented by the slope of a line. So the more classes you take the more it will increase. Therefore the cost for  one class is the rate of change. 
Lastly, the cost for one class is $10. It's not, since $10 is the intial fee to belong to a gym, so this is false. 

Recap:
True
-The relationship is linear
-The y-intercept represents the monthly fee.
-The rate of change represents the cost for one class.
False
-The relationship represents a continuous function. 
-The cost for one class is $10.

37,000,000-3,000,000=34,000,000=(34,000,000)/1

The population of Chicago is 3,000,000. That's 34,000,000 less than the amount of people who died and became wounded during World War 1.

MAVERICK [17]

Answer:

g = 136

Step-by-step explanation:

g + 24 = 160 is your equation.  then you subtract 24 to each side and get

g = 136.

How do you solve linear equations with substitutions?
Nostrana [21]

Answer:

The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.

Step-by-step explanation:

Solve the following system by substitution.

2x – 3y = –2

4x +   y = 24

The idea here is to solve one of the equations for one of the variables, and plug this into the other equation. It does not matter which equation or which variable you pick. There is no right or wrong choice; the answer will be the same, regardless. But — some choices may be better than others.

For instance, in this case, can you see that it would probably be simplest to solve the second equation for "y =", since there is already a y floating around loose in the middle there? I could solve the first equation for either variable, but I'd get fractions, and solving the second equation for x would also give me fractions. It wouldn't be "wrong" to make a different choice, but it would probably be more difficult. Being lazy, I'll solve the second equation for y:

4x + y = 24

y = –4x + 24

Now I'll plug this in ("substitute it") for "y" in the first equation, and solve for x:

2x – 3(–4x + 24) = –2

2x + 12x – 72 = –2

14x = 70

x = 5

Need help pleaseeeee
Orlov [11]

Answer:     cools rapidly

Step-by-step explanation:

Some igneous rocks contain crystals of very different sizes. These

rocks formed from magma that started cooling within Earth and then

erupted onto the surface. The large crystals grew as the magma cooled

slowly. The small crystals grew as the lava cooled quickly.

Hope this helps!
