#3.

Let's first make an equation out of the information given about Frank: y = -15x + 630.

Then, we can plug in 20 for x to find out how many bricks he has after 20 minutes.

-15(20) + 630 = 330

So, Frank has 330 bricks left after 20 minutes. If we look at the graph, find 20 minutes on the x-axis, and follow that up to where it meets with the line, we can see that Francis has only 320 bricks remaining after 20 minutes.

Therefore, Francis will have the fewest bricks left after 20 minutes.

#2.

First, we need a bit of information about both of the functions: the slope and y-intercept. The slope of function W is 1/2, and the y-intercept is -1. The slope of function Z is 1/4, and the y-intercept is -2. Now, let's take a look at the options.

1. False - 1/2 is greater than 1/4

2. True - 1/2 is greater than 1/4

3. False - -2 does not equal -1

4. False - -1 is greater than -2 (closer to 0)

5 & 6. False - The y-value when you plug -4 into function W is -3, and the y-value when you plug -4 into function Z is also -3.

#1.

This problem involves using the slope formula for functions A and B, and finding m in the equation for function C.

Slope of function A = 2

Slope of function B = 3/5

Slope of function C = 3

Therefore, in order from least to greatest is: B, A, C.

Hope this helps!! :)

So these are basically isolating the variables.
The first equation is 3g + 5 =17.
In order to isolate the variable, we would have to get g by itself, that means 5 would have to go. In order to do this, we would do the opposite. Since it is positive 5 we would add negative 5, in order for it to disappear. This works because a positive 5 and negative 5 cancel each other out. Whatever you do to one side of the equation you have to do to the other, since we subtract 5 on one side we have to subtract 5 on the other. Therefore we would do 17-5.
Now we have 3g=12
We know that 3g is basically 3 multiplied by g. The opposite of multiplication is division.Therefore we would divide by 3 on both sides.
The answer to the first question would be g= 4.
And if you want to check if your answer is correct you plug the value in.
So
3(4) + 5 =17
