The black line represents your equation from Question 7. Compare the black and blue lines.

Include in your answer:

*Slope-intercept form (y=mx + b) of the blue line. Show or explain your work.
*Which line has the greater slope? How do you know?


Hint: Find the y-intercept. Then count up and over (y/x) to the next point on the line to determine the slope.

Answers

Answer:

The black line has the greater slope.

Step-by-step explanation:

One way to think about which line has the greater slope is to imagine (or draw) a car on top of each line driving from left to right. If the car is driving up a steeper hill then the slope is greater.

To show your work though, starting at the y-intercept on the black line, find another point that you can see well on the line such as (3, 4). To get from the y-intercept to (3,4) go up 2 and right 3 so the slope is 2/3.

For the blue line, find a point that is easy to see such as (2, 3). To get from the y-intercept to (2, 3) go up 1 and right 2 so the slope is 1/2.

(Remember slope is y/x or rise/run)

Since 2/3 is bigger than 1/2, the slope of the black line is greater.

help me do examples for a function and a non function

Answers

Answer:

{(1,2) (3,4) (5,6)} and {(1,2) (1,4) (5,6)}

Step-by-step explanation:

you really want to think of a function as a vending machine. if you press B12 on a vending machine because thats where the chips are, only the chips should come out. in a function, the input value aka x (B12, what youre putting in) should only have one output value aka y, (the chips)

an example of a function would be {(1,2) (3,4) (5,6)}

an important thing to remember is that one output value can belong to multiple input values. there can be chips (output) in both B12 and C12 (inputs) BUT as i said before, there CANNOT be two outputs for one input. B12 cannot give you both chips and a drink.

using this, another example of a function would be {(1,2) (3,2) (5,2)}

an example of an non function would be {(1,2) (1,4) (5,6)} because x, the input value, has multiple output values which is not possible. the output of 1 can not be 2 and 4 at the same time which we can see in the (x,y) coordinates.

How many cubes with the side lengths of 1/3 ft completely fill the prism?

Answers

Answer:

48 cubes

Step-by-step explanation:

To begin, we must find the volume of both the cube and the rectangular prism.

The volume of a cube is a side to the 3rd power.

1/3 · 1/3 · 1/3 = 1/27

The volume of a prism is l * w * h.

2/3 · 1 · 8/3 = 16/9

Now, we have the volume of a cube and the prism. Since we have the find how many cubes can fit into the prism, we must divide 16/9 by 1/27.

16/9 ÷ 1/27 = 16/9 · 27/1 = 432/9 = 48/1 = 48

Therefore, 48 cubes will fit into the prism.

We’ll start off by multiplying all 3 as it is a rectangular prism. turn 2 2/3 improper; 8/3.
1 can be 3/3.

and 2/3 is 2/3. So when you multiply

8/3 x 3/3 x 2/3 gives 48/27.

now: since it is a cube all the sides are the same

1/3 x 1/3 x 1/3 is 1/27.

48/27 divided by 1/27 is 48

Answer 48.

But with the information provided, the base times  height is equal to 150 Ft^2. Check out the Kahn Academy video for a better explanation  

the answer is 150^2 because the formula is A=bh which stands for Area=base X height and since the base is 15 and height is 10, you would do 15x10 which equals 150^2
