Albert receives $0.30 per pound for 1 to 49 pounds of glass bottles he recycles. He receives $0.40

Mathematics

Answer:

Yes

Step-by-step explanation:

The amount of money Albert receives is described by the expression

y = \begin{cases}0.30x  & \quad \text{if } 0 \leq x \leq 49 \\0.40x & \quad \text{if } x > 50\\\end{cases}

The graph is shown below.

To determine if the relation is a function,  we can use the vertical line test:  

If a vertical line crosses the graph more than once in any location, the relation is not a function.

We see that at no place will a vertical line intersect the graph more than once.

The relation is a function.

Is this correct? please help me ​
Aleksandr [31]

Correct Answer:

y = -1/3x

Step-by-step explanation:

I see what you were tying to do and you did a good job at trying but the slope is negative 1/3, not negative 1. To find the slope, you have to divide the y by the x for example point (3, -1)

-1 ÷ 3 = -1/3

Remember the phrase Rise over Run where the Rise is y and Run is x

Hope you have a good day and luck in finding good memes!

jennifer had 3/5 of a gallon of liquid shampoo and divided it evenly among 4 other bottles. How many gallons did she put into ea
kirill [66]
If the 3/5 was a whole number, it would all be simple. We would just put the number above 4 and divide. Easy, right?

Well, you do basically the same thing. Since having fractions over fractions confuse me, I'm going to put 3/5 into a decimal.
3/5=6/10=0.6

Now, I put that over 4, because there are 4 bottles.
0.6/4=6/40=3/20

She put 3/20 gallons into each bottle. Hope this helped!

Find the area of the figure
Evgesh-ka [11]
These are the steps: 
1. Find area of the two triangles.
2. Find area of the rectangle.
3. Add them up.

<u>Step 1: Find area of the two triangles:</u>

Formula : Area of triangle = 1/2 x base x height

Both triangles are identical.
Height = 5m
Base = 6 + 6 + 12 = 24

Area = 1/2 x 24 x 5 = 60 m²

<u>Step 2: Find the area of the rectangle:</u>

Formula : Area = Length x Width

Area = 12 x 7 = 84 m²

<u>Step 3: Find the total area:</u>

60 + 84 = 144 m²

Answer: 144 m²
