If two variables x and y are directly proportional, then as x rises, y will rise accordingly, and as x falls, y will fall accordingly. So, y=k x can be written.
The equation for k=y/x is k=b/p.
What exactly is a constant proportion?the proportional relationship between two variables that is always constant.
Constant ratio, constant rate, constant of variation, or even changing rate are examples of proportionality constants.
Describe continuous rate.When the ratio of the output to the input remains constant at every given point along the function, the rate of change is said to be constant.
The slope is another name for the constant rate of change.
The rate of change for linear functions will be constant.

Please classify the following equations as parallel, perpendicular, intersecting, or coinciding (same line):
y = 3x + 2
9x - 3y = -6
Answer:
Intersecting
Step-by-step explanation:
Parallel lines means it will have the same slope, and perpendicular means the slope will be it's reciprocal, so the slope would be 1/3 x instead of 9x. Conciding means it's the exact same equation, so the answer has to be intersecting.

Answer:
Basically, you need to plug 5 in as y
Step-by-step explanation:
First, plug 5 in the place of Y 10 * 5 + 6
Then solve the equation from there.

The number of people who attend a concert varies directly with the amount of money spent on advertising. If 790 tickets are sold when $2,547.75 is spent on advertising, how much money needs to be spent on advertisements to get a sellout crowd of 1500?
Answer:
$4837.5
Step-by-step explanation:
Given that,
790 tickets are sold when $2,547.75 is spent on advertising.
We need to find the money to be spent on advertisements to get a sellout crowd of 1500.
It is also mentioned that the number of people who attend a concert varies directly with the amount of money spent on advertising. Let money be x. So,
[tex]\dfrac{790}{2547.75}=\dfrac{1500}{x}\\\\x=\dfrac{2547.75\times 1500}{790}\\\\x=\$4837.5[/tex]
So, $4837.5 is spent on advertisements to get a sellout crowd of 1500

Eugene borrows $250 at a 4% annual interest rate. If he does not make any payments, how much simple interest will he owe in 18 months?
I promise this the last one but how do you do these type of problems?
Answer:
0.96 + 0.43v
Step-by-step explanation:
You simplify, v and -0.57v are like terms, therefore you can add them together
v - 0.57v = 0.43 v
Answer:
0.96 + 0.43v
Step-by-step explanation:
What you are doing is combining like terms. Let's say v is candy I have v - .57v that means I have one candy and I ate .57 of it already so we subtract to get .43v and the .96 is brussel sprouts. We do NOT want to mix the candy and the brussel sprouts because they are different things.

A string measures 30 centimeters. About how many inches long is the string?
A. 11
B. 11.8
C. 15
D. 20
Answer:
B
There are 2.54 centimeters to every inch.
30/2.54 is 11.8
The length of the string in inches in 11.8.
In order to determine the length of the string in inches, the unit of conversion of centimeters to inches have to be first determined. 1 centimeter is equivalent to 0.393701 inches.
1 cm = 0.393701 inches
The second step is to multiply the length of the string in centimeter by the unit of conversion.
Length of string x unit of conversion
30 x 0.393701
= 11.8 (to one decimal place).

What is the value of x?
Answer:
x = 98
Step-by-step explanation:
x = 53 + 45
x = 98
note: the measure of an ext. angle of a triangle is equal to the sum of the two non-adjacent interior angles.
Answer:
98
sum of angle in this triangle = 180
180-(53+45) = 82
so, the third angle is 82 degrees.
moving forward, the third angle (82 degrees) and angle x are straight line angle,
therefore, x + 82 = 180
x =180-82

Given:
The number is .
To find:
The correct values for each blank.
Solution:
The given number is .
We know that, 10 lies between two consecutive perfect squares 9 and 16, . repeating is located between the square roots of these two numbers.
This means repeating is located between 3 and 4.
So, repeating is less than 5.
Therefore, Blank-1=9, Blank-2=16, Blank-3=3 and Blank-4=4.
The number √10 is less than 5.
Because 10 lies between two consecutive perfect squares 3 and 4.
What is square root of a number?
A square root of a number is a value that multiplied by itself gives the same number.
Given that;
The number is √10.
Now,
The value of √10 = 3.16
Which is less than 5.
Hence, 3.16 < 5
Since, The value of 3² = 9
And, The value of 4² = 16
Thus,
3² < 10 < 4²
So, The number √10 is less than 5.
Because 10 lies between two consecutive perfect squares 3 and 4.
