Answer:

Y=15x

Step-by-step explanation:

So easiest way to do slope is to count rise over run. But this question is tricky because it’s not the same spaces in each increment.
Like the x is 1,2,3,4 and the y is 15,30,45,60 etc.

So the formula is y=mx+b
m stands for slope
b is for y intercept. That means what is the y when x is 0.

So first slope. m=y2-y1/x2-x1 or rise/run. Rise as in the y axis and run as in the x axis.

So let’s use the first 2 points. (0,0) (1,15)
15-0/1-0= 15/1= 15
So m=15

For b, when x is zero, y is also zero. So you would just leave that part out. I mean I guess you can put a +0 but it’s unnecessary.

So y=15x

Ps. You can also try diff points for m. 30-15/2-1 = 15/1=1 ect. Even like 60-15/4-1= 45/3 = 15

The price of one share of a stock fell $4 each day for 8 days. By how much did the value of the stock change in the time period?

A. $32
B. $24
C. -$24
D. -$32

Answers

Answer:

D. -$32

Step-by-step explanation:

Multiply 4 by 8. If the stock went down, it would be -$32.

D (-32)

$4 multiplied by 8 days (4x8) would be $32, and since the stock is falling it would be -32

In her science classroom Jane noticed that the lengths (in inches) and the weights (in ounces) of the class's pet snakes were directly related by the equation y = kx, where x is the length and y is the weight. Use the information in the table to find k, the constant of proportionality?A.25.0 B.27.5 C.30.0 D.32.5

Answers

Answer:

Step-by-step explanation:

multiply by 2 then add half of the original number

The constant of proportionality(k) is 5/2 and the corresponding weight is

30 ounces for 12 inches.

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, The lengths (in inches) and the weights (in ounces) of the class's pet snakes were directly related by the equation y = kx.

Now, when x = 6, y = 15

15 = 6k.

k = 15/6.

k = 5/2.

Now, when length(x) is 12 then,

y = 12(5/2).

y = 30.

Answers

Answer:

The properties of the Real Number System will prove useful when working with equations, functions and formulas in Algebra, as they allow for the creation of equivalent expressions which will often aid in solving problems. In addition, they can be used to help explain or justify solutions.

Understanding the properties of real numbers will help us simplify numerical and algebraic expressions, solve equations, and more as you progress in studying algebra. In other words, the properties or axioms of real numbers are just one of many basic foundations of mathematics

I don´t know about scale factor so I will also say 5

Answers:

Scale factor = 1/5B = 5

===========================================

Explanation:

Look at the left most sides of each figure. Dividing the smaller side over the larger leads to 7/35 = (1*7)/(5*7) = 1/5. This is the scale factor. It means the blue figure's side lengths are 1/5th of the orange figure's corresponding side lengths.

So that explains why your teacher put A = 20(1/5) = 4

Multiplying the orange side lengths by the scale factor gets you the blue side lengths.

Now focus your attention on the far right most side lengths of 25 and B

We can see that B = 25(1/5) = 5 feet.
