Solve 3(y-2)=6(y-1)-3y
Answer:
All real numbers are solutions.
Step-by-step explanation:
1. First you want to distribute what is inside the parenthesis. You would want to do 3 × y + 3 × -2 = 6 × y + 6 × -1 -3y.
2. Now that the equation has been distributed, you want to simplify it. 3 × y is equal to 3y, and 3 × -2 is equal to -6. So, 3y + -6 = 6 × y + 6 × -1 -3y.
3. Now you want to simplify the right side of the equation. So, 6 times y is equal to 6y, and 6 × -1 is equal to -6. Now the new equation is 3y + -6 =6y + -6-3y.
4. Also in an equation, if there is a + and - sign together like this +-, it would equal to -. So, 3y + -6 = 6y + -6-3y, is equal to 3y - 6 = 6y -6-3y.
5. Now you want to combine like terms on the right side of the equation. 3y - 6 = 3y -6 because 6y-3y is equal to 3y.
6. Now the rest of the equation has to be combined using like terms. Start by moving the -3y fromthe right side of the equation to the 3y on the left side of the equation. -3y plus 3y is equal to zero so it cancels out. The 3y on the left side plus another 3y is equal to 6y.
7. Now the equation is 6y - 6 = 6y - 6
8. You can add 6 to the -6 on both sides of the equation which would cancel out on both sides leaving you with an equation of 6y = 6y.
9. Divide both sides by 6 to get y = y.
10. This equation means that all real numbers are solutions to this equation. In other words, no matter what real number you use in this equation, it would come out to be true. For example, if y = 3, 3 = 3, so the equation is true.

4x + 11y = 36, What is the x intercept (let y = 0)? *
To find the x intercept we must put zero instead of the y in the function.
Let's do it....
[tex]4x + 11(0) = 36[/tex]
[tex]4x + 0 = 36[/tex]
[tex]4x = 36[/tex]
Divided sides by 4
[tex] \frac{4}{4}x = \frac{36}{4} \\ [/tex]
[tex]x = 9[/tex]
Thus the x intercept is 9 .
And we're done....

the image if the point (5,-1) under a reflection in the y-axis is
the reflected image of the point (5,-1) under the y-axis is (-5, -1).
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given a coordinate (5, -1), find the image of the coordinate under a reflection in the y-axis.
Since
When a point is reflected in the x-axis, the sign of its ordinate changes. When a point is reflected in the y-axis, the sign of its abscissa changes. When a point is reflected in the origin, the sign of its ordinate and abscissa both change.thus, Coordinates of image = (-5, -1)
Therefore, the image of the point (5,-1) under a reflection in the y-axis is (-5, -1).

Answer:
25
Step-by-step explanation:
let x represent the first consecutive number.
let x+1 represent the second consecutive number.
let x+2 represent the third consecutive number.
x + x+1 + x+2 = 72
3x + 3 = 72
3x = 72 - 3
3x = 69
3x/3 = 69/3
x= 23
first number= x = 23
second number = x+1
= 23+1

What percent of $18 is $6?
33.333% (with the 3 repeating)
1/3 of 18 is 6, so 33.333% (with the 3 repeating) of 18 would be 6.
Answer:
33.333% (its a repeating 3)
Step-by-step explanation:
$6 is 33.33% of 18.
I got this number by dividing 6 by 18, which gave me 0.33333333333.
I then converted 0.33333333333 to a percentage, rounded, and got 33.33%.

An electronics company is changing its internet advertising from a banner advertisement to a pop-up advertisement. The cost of the banner advertisement in dollars is represented by the function C(n) = 0.30n + 5.00 where 'n' is the average number of hits per hour and $5.00 is just a flat-rate cost.
1.) The cost of the pop-up advertisement will double the cost per hit. The equation for this new cost function will be D(n) =
2.) This change does/does not shift the function vertically and/or horizontally.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Cost function of banner advertisement:
C(n) = 0.30n + 5.00
n = average number of hits per hour
5 = flat rate
From the function, C(n), the cost per hit is the slope value of the function ; which is 0.30
1.) If the cost of pop-up advert will double the cost per hit, the cost function for pop-up advert will be :
D(n) = 2(0.30n) + 5
D(n) = 0.60n + 5.00
B.) This change in cost per hit has resulted in change in slope which is defined as :
[Rise / run = vertical change / horizontal change].
Hence, both vertical and horizontal change has occurred.
N entry level technical writer's annual pay is $55,068 based on 52 weeks per year. Due to the economy, his company is having to cut back on the number of weeks that it employs its technical writers.

Witch expression is equivalent to 1/5(150x - 80y + 50 - 50x- 25y + 20)?
Answer:
20x - 21y + 14
Step-by-step explanation:
1/5(150x - 80y + 50 - 50x- 25y + 20)
Step 1 - Distribute
1/5 • 150x = 30x
1/5 • (-80y) = -16y
1/5 • 50 = 10
1/5 • (-50x) = -10x
1/5 • (-25y) = -5y
1/5 • 20 = 4
Step 2 - Combine Variables
30x - 10x = 20x
-16y - 5y = -21y
10 + 4 = 14
Step 3 - Arrange the Set of Numbers
20x - 21y + 14

B) $13.50 for 10 bagels
c) $3.30 for 6 bagols
D) $5.00 for 12 bagets
E) $8.10 for 18 bagels
Options B, C, D, and E have a unit price for bagels that is greater than the unit price Caleb pald because all their unit prices are higher then what Caleb paid.
How to calculate unit price of something?Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.
unit price of something is price of 1 thing.
LEts suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.
Given that Caleb paid $4.50 for 12 bagels.
Unit price = 4.50 / 12 = 0.375
A) $2.25 for 6 bagols
Unit price = 2.25 / 6 = 0.375
B) $13.50 for 10 bagels
Unit price = 13.50 / 10= 1.35
c) $3.30 for 6 bagols
Unit price = 3.30 / 6 = 0.55
D) $5.00 for 12 bagets
Unit price = 5.00 / 12 = 0.41
E) $8.10 for 18 bagels
Unit price = 8.10 / 18 = 0.45
Hence, Options B, C, D, and E have a unit price for bagels that is greater than the unit price Caleb pald because all their unit prices are higher then what Caleb paid.

Answer 16
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
The equation would be 130% x N = 20.8
To solve you would have to switch the equation around and to do that you would divide. 130% is the same as 1.30 or 1.3
20.8 ÷ 1.3 = 16
N = 16
