Answer:
y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]
Step-by-step explanation:
Given
x = a - 2by² ( add 2by² to both sides )
x + 2by² = a ( subtract x from both sides )
2by² = a - x ( divide both sides by 2b )
y² = [tex]\frac{a-x}{2b}[/tex] ( take the square root of both sides )
y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]
Answer:
[tex]y = a - x \di2b[/tex]
Step-by-step explanation:
[tex]2b {y }^{2} = a - x[/tex]
[tex]2b {y}^{2} \div 2b = a - x \ \div 2b[/tex]
[tex] {y}^{2} = a - x \div 2b[/tex]
[tex]y = \sqrt{a - x \div 2b} [/tex]

\(` u`)/
Answer:
X-18
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 6-x-(-12)=0
Solve : -x+18 = 0
Subtract 18 from both sides of the equation : -x=-18
Multiply both sides of the equation by (-1) : x = 18

The length of a rectangle is eight more than twice its width. The perimeter is 88 feet. Find the dimensions of the rectangle.
A w = 10 ft, l = 18 ft
B w = 16 ft, l = 28 ft
C w = 18ft, l = 24 ft
D w = 12 ft, l = 32 ft
Answer:
D w = 12ft, l = 32ft
Explanation:
Make an equation for your length based on the given information.
l = 2w + 8
Make an equation using what you know about the perimeter
p =2l + 2w, p = 88
88 = 2l +2w
Substitute in your previous equation for l.
88 = 2(2w + 8) + 2w
Distribute and simplify.
88 = 4w + 16 + 2w
88 = 6w + 16
72 = 6w
w = 12
Now you can solve for l using the first equation.
l = 2(12) + 8
l = 32
Your answer is w = 12fr, l = 32ft. You can check your work by plugging the values back into the perimeter equation.
Gershon lives 3 10 mile from the soccer fields. How far does Gershon walk if he walks from home to the soccer fields and back home? How many miles did he walk
Answer:
Gershon walked 620 mile
Step-by-step explanation:
From the question,
Gershon lives 310 mile from the soccer fields,
This means the distance from where Gershon lives to the soccer fields is 310 mile.
Likewise, the distance from the soccer fields to where Gershon lives his as well 310 mile.
So, if Gershon walks from his home to the soccer fields, he will cover a distance of 310 mile.
Then, if Gershon walks back home from the soccer fields, he will cover another distance of 310 mile.
Now, To determine how many miles he walked,
Total number of miles Gershon walked = The distance from where Gershon lives to the soccer fields + The distance from the soccer fields to where Gershon lives
Hence, Total number of miles Gershon walked = 310 mile + 310 mile
Total number of miles Gershon walked = 620 mile
Hence, Gershon walked 620 mile

After plugging in j=5, we found that the expression is equal to 50.
Find the slope of the line passing through the points (-18, -5) and (-19, -13)
Answer:
Let (-18, -5) be (x1,y1)
(-19, -13) be (x2,y2)
slope = (y2-y1)/(x2-x1)= (-13+5)/(-19 +18) = 8
Answer: The slope is 8.
Step-by-step explanation: To get the slope you have to do y2 - y1 over x2 - x1. so you take the -5 and subtract -13 from it, which equals 8. Then subtract -19 from -18 which is 1. So you have 8/1 which is 8.

Explain why Figure B is not the image of Figure A after a rotation using center P
Answer:
because the are not the same measurement nor the right placement
Step-by-step explanation:
The sides of figure B appear narrower than the sides of figure A.
We need to explain why Figure B is not the image of Figure A after a rotation using centre P.
What is a rotation?A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point.
Now,
The reason why figure B is not the image of figure A after a rotation using centre P includes
1) The angle of rotation is measured as 180 - 45 = 135°, while the angle of rotation of the base is (90 - 26) + (90 - 71) = 83°
2) Rotation of a figure is a rigid transformation, such that the dimensions of the sides of the pre-image and the sides of the image should be equal after the rotation, however, the sides of figure B appear narrower than the sides of figure A.
Therefore, the sides of figure B appear narrower than the sides of figure A.

Step-by-step explanation:
My favorite group, The Lumineers, is coming to Prescott and YC for a concert. Tickets are sold in three levels, $45, $65, and $95 depending on seats. The auditorium seats 1100 people total on the different levels; for them to come to YC we need to sell $66,500 worth of tickets and the auditorium has as many cheap ($45) tickets as the sum of the other two levels ($65 and $95).
Answer:
550 $45 tickets, so $24750 worth of $45 tickets
Step-by-step explanation:
If $45 tickets=x, $65=y, and $95=z, then the question is saying x=y+z. And if x+y+z=1,100, then x=1100/2, so 550 $45 tickets. 550*45 is $24750

What is the answer to -2r-4r=0
Answer:
r = 0
Step-by-step explanation:
First, combine like terms:
(-2r - 4r) = 0
(-6r) = 0
Isolate the variable, r. Divide - 6 from both sides:
(-6r)/-6 = (0)/-6
r = 0/-6 = 0
r = 0 is your answer.
