Answer:
3
Step-by-step explanation:
The radicals get in the way a bit, so we can define ...
x = √p
y = √q
Then the equation is ...
(x +y)/(1-x) = (4x+y)/(1-x^2)
Multiplying by (1-x^2), we have ...
(x +y)(1 +x) = 4x +y . . . . . . using 1-x^2 = (1-x)(1+x) the 1-x factor cancels
x^2 +xy +x +y = 4x +y . . . eliminate parentheses
x(x +y) = 3x . . . . . . . subtract (x+y)
x +y = 3 . . . . . . . . . . divide by x
This is the sum we're looking for:
√p +√q = 3

This is the table in which we can see the values of two squared, two cubed, and so on. This is an operation in mathematics, known as exponentiation. If we look at the numbers at the bottom line, we can try to find the power value to which 2 must be raised to get this number. For example, to get 16, it is necessary to raise two to the fourth power. And to get a 64, you need to raise two to the sixth power. Also this is totally the answer

Your bank charges you a fixed monthly fee for banking there and a charge for each check you write one month you wrote 23 checks and were charged 16.70 the next month you wrote 18 checks and were charged 15.95 how much is your fixed monthly charge and how much do they charge per check
Answers
Answer:
Your fixed monthly charge is $13.25 and the charge per check is $0.15.
Step-by-step explanation:
The formula to calculate the amount the bank charges you would be equal to the fixed monthly fee plus the charge for each check for the number of checks. According to that, if you wrote 23 checks and were charged 16.70, this would be:
x+23y=16.70
Also, if you wrote 18 checks and were charged 15.95, you would have the following equation:
x+18y=15.95
You can use these equations to find the value of x and y:
x+23y=16.70 (1)
x+18y=15.95 (2)
where x is the fixed monthly fee and y is the charge for each check
First, you can solve fo x in (1)
x=16.70-23y (3)
Then, you can (3) in (2):
16.70-23y+18y=15.95
16.70-5y=15.95
16.70-15.95=5y
0.75=5y
y=0.75/5
y=0.15
Finally, you can replace the value of y in (3) to find x:
x=16.70-23(0.15)
x=16.70-3.45
x=13.25
According to this, the answer is that your fixed monthly charge is $13.25 and the charge per check is $0.15.
What is an equation of the line that passes through the points (3, 8) and (1,0)?
Answers
Answer:
y = 4x - 4
Step-by-step explanation:
first, find the slope:
y2 - y1/ x2 -x1
8 - 0/ 3 - 1 = 4
no plug in your slope and one of the points to find the b:
y = mx+b
0 = 4 (1) + b
b= -4

The answer is proportion. A proportion basically equates two ratios.
A statement that two ratios are equal is called a proportion.
In a proportion, the four quantities involved are related in such a way that the first ratio is equal to the second ratio. It can be represented in the form of "a:b = c:d," where "a" and "b" are the terms of the first ratio, and "c" and "d" are the terms of the second ratio.
Proportions are used in various mathematical applications, such as solving problems involving ratios, scaling, similarity, and solving for unknown values. They provide a way to compare quantities and establish relationships between them based on their relative sizes.

[tex]9d = 36[/tex]
Step-by-step explanation:
See attachment for complete question
[tex]Length = 36ft[/tex]
[tex]n = 10[/tex]
From the question, we understand that one shrub must be at both ends.
Taking the first as a point of reference, we're left with:
[tex](n - 1) * distance = 36[/tex]
Substitute 10 for n and d for distance
[tex](10 - 1) * d = 36[/tex]
[tex]9 * d = 36[/tex]
[tex]9d = 36[/tex]
Hence:
