Answer:
x = y + b - a
Step-by-step explanation:
Given
y = x + a - b ( add b to both sides )
y + b = x + a ( isolate x by subtracting a from both sides )
y + b - a = x
Six times a number equals 3 times the number, increased by 12. Find the number
Answer:
x=4
Step-by-step explanation:
"A number" can be rewritten as X:
6x=3x+12
1) subtract 3x on both sides:
3x=12
2) divide both sides by 3:

A rectangle has a length of 27 feet less than nine times its width. If the area of the rectangle is 972 find the length of the rectangle
The length of Rectangle is 81 feet's.
We have a rectangle which has a length of 27 feet less than nine times its width and the area of the rectangle is 972.
We have the length of the rectangle.
State the formula to calculate the Perimeter and Area of Rectangle?The Area of a Rectangle = A = L x B
The Perimeter of a Rectangle = P = 2(L + B)
According to the question, we have -
Area = 972 square feet's.
Let the length of rectangle be x and width be y.
Then -
x = 9y - 27
Now -
Area = 972
xy = 972
y(9y - 27) = 972
9y(y - 3) = 972
y(y - 3) = 108
[tex]$y^{2} -3y -108 = 0[/tex]
(y - 12)(y + 9) = 0
y - 12 = 0 or y + 9 = 0
y = 12 or y = - 9
But width cannot be negative. Therefore -
y = 12.
Now, length = x = 9y - 27 = 12 x 9 - 27 = 108 - 27 = 81.
Hence, the length is 81 feet's.

Nine less than a number is between 3 and 8. Find the range of numbers that make this true.
Answer:
The range of the numbers make this true is (12 , 17)
Step-by-step explanation:
Lets explain how to solve the problem
The statement is:
→ Nine less than a number is between 3 and 8
Assume that the number is x
∵ The number is x
∴ Nine less than a umber is x - 9
→ The difference is between 3 and 8
∴ 3 < x - 9 < 8
∴ Nine less than a number is between 3 and 8 ≡≡≡ 3 < x - 9 < 8
Lets solve the inequality to find the range of x
∵ 3 < x - 9 < 8
Add 9 to each side
∴ 3 + 9 < x - 9 + 9 < 8 + 9
∴ 12 < x < 17
∵ There is no mention about the type of the number that is integer or
rational number or real number
∴ The range of x is any number between 12 and 17
The range of the numbers make this true is (12 , 17)
Remember you can use any number between 12 and 17 but you
cannot use 12 or 17
The range of numbers that make this true is (12, 17).
Let the numbers be represented by x.
Therefore, based on the information given, the number will be:
x - 9 = 3
x = 3 + 9
x = 12
The first number is 12.
x - 9 = 8.
x = 8 + 9
x = 17
Therefore, the range of numbers that make this true is (12, 17).

How many times does the quadratic function below intersect the x-axis?
y = 2x2 +7x+6
Answer:
once
Step-by-step explanation:
since the equation is liner, with x simply to the first power, it will only cross the x axis once. x^2 would cross the x axis twice, x^3 would cross it three times, and so on
Given quadratic function [tex]y = 2x^{2} +7x+6[/tex] intersects the x-axis two times.
What is quadratic function?" Quadratic function is defined as the function which has variables with highest degree two."
According to the question,
Given quadratic function,
[tex]y = 2x^{2} +7x+6[/tex]
If quadratic function intersect x-axis value of [tex]y=0[/tex] we have,
[tex]2x^{2} +7x+6 =0\\\\\implies 2x^{2} + 4x+3x + 6=0\\ \\\implies 2x(x+2) + 3(x+2)=0\\\\\implies (2x+3) (x+2)=0\\\\\implies 2x+3 =0 \ or \ x+2=0\\\\\implies x = \frac{-3}{2} \ or \ x =-2\\\\\implies x = -1.5 \ or \ x =-2[/tex]
As shown in graph , quadratic function intersect x-axis at two points [tex](-2,0)[/tex] and [tex](-1.5,0)[/tex].
Hence, given quadratic function [tex]y = 2x^{2} +7x+6[/tex] intersects the x-axis two times.

Solve y = x + 4 for x.
x = y − 4
x = y + 4
x = −y + 4
x = −y − 4
Answer:
x=y-4
Step-by-step explanation:
y=x+4
-4
y-4=x
Answer:
Option A.
Step-by-step explanation:
y = x + 4
As we know if we perform a similar operation on both the sides of the equation it doesn't affect the parent equation.
So we subtract 4 on both sides of the equation
y - 4 = (x + 4) - 4
x = y - 4
Therefore, option A. will be the answer.

Julian saved between $ 30 and $ 52 over the summer. His friend Daniela saved twice as much. Let n represent the amount of money Julian saved. Write and solve an inequality to represent the amount of money Daniela saved.
Answer:
$60 - $104
Step-by-step explanation:
Based on what we know, we double $30 and double $52 which gives us $60 and $104. As we don't know the exact number we need to double we do that. This tells us that Daniela saved between $60 - $104.
If Julian saved between $ 30 and $ 52 over the summer. The inequality represents the amount of money Daniela saved which will be $ 60 < n < $ 104.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
For the inequality, we have to apply the arithmetic operation in which we do the multiplication of x and apply the inequality for the given data.
It is given that,n represents the amount of money and Julian saved between $ 30 and $ 52 over the summer.
The inequality represents the amount saved by Julian is,
$ 30<n<$ 52
If Daniela saved twice as much then he saved the amount between $ 60 and $ 104.If n shows the inequality for the amount Daniela saved then the inequality is shown as,
$ 60<x<$ 104
Thus, if Julian saved between $ 30 and $ 52 over the summer. The inequality represents the amount of money Daniela saved which will be $ 60 < n < $ 104.

In a community garden (shown to the right) you want to plant and fence in a vegetable garden that is adjacent to your friend’s garden. You have at most 54 ft of fence, and the fence must surround all four sides of your garden. What are the possible lengths of your garden
To find the possible lengths of the garden, use the perimeter formula and solve the inequality x <= 27 ft.
Explanation:To find the possible lengths of your garden, you need to determine the perimeter of the garden. Since you have at most 54 ft of fence, the perimeter must be less than or equal to 54 ft.
Let's assume the length of your garden is 'x', then the width would be (54 - 2x)/2.
The perimeter formula is P = 2L + 2W, so substituting the values we have, 2x + 2[(54 - 2x)/2] <= 54.
Simplifying this inequality, we get x + 54 - 2x <= 54. Solving for 'x', we get x <= 27.
Therefore, the possible lengths of your garden are any value less than or equal to 27 ft.
