Solve 2y+1−x=7x for y
Answer:
Y=4X-1/2
Step-by-step explanation:
You must isolate the variable by dividing each side by factors that dont contain variables.
Answer:
y = 4x - 1/2
Step-by-step explanation:
2y + 1 − x = 7x
2y = 7x + x - 1
2y = 8x - 1
y = (8x - 1)/2
y = 4x - 1/2
Factor the quadratic expression completely.

After being marked up 40%, the sale price of a tennis racket is $87.50 What was the original price of the tennis racket?
Answer:
$62.50
Step-by-step explanation:
The original price is x
It is marked up 40 percent
x+.40x = new price
1.40x = new price
The new price is 87.50
1.40x = 87.50
Divide each side by 1.40
1.40x/1.40 = 87.50/1.40
x =62.50
The price before mark up is 62.50
Answer:
$62.50
Step-by-step explanation:
After mark up, price is
100 + 40 = 140% of cost
140/100 × Cost = 87.50
Cost = 87.50 × 100/140
Cost = $62.50

How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5.
In other words, an equation is a set of variables that are constrained through a situation or case.
To form an equation we must know the constraint of that condition,
For example x < 5 is a constraint.
Another example of a constraint is;
7x + 3y = 8 like that
Let say
Your age is = x
21 year ago your age were = x - 21
Now it was half the age x so,
x - 21 = (1/2)x
2x - 42 = x
x = 42
So your current age will be 42 years old.

a basketball player attempted 15 baskets in the game he makes 9 of the attempted baskets which ratio describes the number of baskets the player made to the number of baskets to play attempted thanks so much!!
Answer:
3:5
Step-by-step explanation:
We are given that
Basket player attempted basket=15
He makes number of attempted basket=9
We have to find the ratio which describes the number of baskets the player made to the number of baskets to play attempted.
[tex]\frac{number\;of\;baskets\;made}{number\;of\;basket\; to play attempted}=\frac{9}{15}[/tex]
[tex]\frac{number\;of\;baskets\;made}{number\;of\;basket\; to play attempted}=\frac{3}{5}[/tex]
Hence, the ration which describes the number of baskets the player made to the number of baskets to play attempted=3:5
Answer:

A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 85% pure antifreeze. The company wants to obtain 255 gallons of a mixture that contains 60% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed?
Answer:
75 gallons of water
180 gallons of premium anti-freeze
Step-by-step explanation:
X + Y = 255
X = 255 - Y
0.85Y = 0.6(255)
0.85Y = 153
Y = 180
X = 255 - 180
X = 75

Equation is y=kx. We have four chance to figure out k; hopefully they all give the same result
x=9, y=63, y=kx becomes 63=k(9) so k=63/9=7
x=4, y=28, 28=k(4), k=7
The constant of proportionality is 7; we check 2×7=14, 11×7=77
Answer: k=7, y=7x
Answer:
y=kx
y=k(7)x
y=7x(11)
y=7*11
y=77
Step-by-step explanation:
So with useing the equation that I used the porportional relationship is 7 so just fill 7 in for k. Then take the x number and fill it in for x. you will then multiply and get the y value.

Answer:
x = -2.5 or -5/2

-x = 10/4
x = -10/4
x = -2.5
2. Check Answer
2( -2.5) = 3( -2.5) + 10/4

The Kendall family was preparing to go hiking with the Smith family. In preparation,
the Kendall's bought 8 Cliff Bars and 4 appleslfor $12.40. The Smith family spent
$24.30 on 15 Cliff Bars and 9 apples. What is the difference in price between a cliff
bar and an apple?
Answer:$9.3 is the bars and the rest is the apples
Step-by-step explanation:because you take away from the bars than what is left is the apples.
The difference in price between a cliff bar and an apple is $0.50.
To determine the difference in price between a cliff bar and an apple, we must create two equations based on the information provided:
8C + 4A = 12.40 (equation 1 for the Kendall family)
15C + 9A = 24.30 (equation 2 for the Smith family)
We can solve these equations using substitution or elimination. Let's use the elimination method:
Multiply equation 1 by 2 to get 16C + 8A = 24.80 (equation 3).
Subtract equation 3 from equation 2: (15C + 9A) - (16C + 8A) = 24.30 - 24.80 which gives us -C + A = -0.50.
From this simplified equation, we gather that the price difference between a cliff bar and an apple is $0.50.
Therefore, the difference in price between a cliff bar and an apple is $0.50.
rip van winkle sell asleep for a very long time when he fell asleep, his beard was 8 millimeters long and each passing week and grew 2 additional millimeters
graph the relationship between the length of rip van winkle‘s beard (in millimeters) and time (in seconds)
please answer asap
Answer:
Time in weeks you mean not seconds.
His beard should be graphed at point xy 1, 8 and continue at a gradient rate 8 rise / 1 rise showing m = 8/1 . to show one week to be able to meet up with .
Step-by-step explanation:
There are 604800 seconds in a week so first multiply by 5.5 weeks to find the first green dot. 604800 x 5.5 = 3326400 so we know the .5 option shows a rounded next week number.
We can either work downwards to zero or start at 1,8 ever way they will be even balance as 8/32 = 4 8/36 = 4.4 growth and this for example would show a rounded amount, so that 8/8 would be 8 and show the first week, or can be skipped out and start with y = 2x + 10 and then when referring to show .5 growth it would still be a whole number within the equation representing 12 and still be a whole number representing 2 weeks.
The graph does not speak of seconds but weeks, but if you want to use the above and try for 604800 seconds as shown for 1 week, you will have a tough time graphing. Stick to 2,4,6 8, 10, 12, 14, 16, 18 weeks multiplied by 12 = y = 1 + 8 = 0
y = 2x +8 +2 = 1
y = 3x + 8 +2 = 2

Write the equation in vertex form for the graph below.
Given:
The graph of the parabola with vertex (-2,-4)
We need to determine the equation of the parabola in vertex form.
Equation in vertex form:
The general form of the equation of the parabola in vertex form is given by
[tex]y=a(x-h)^2+k[/tex]
where a is the constant and (h,k) is the vertex.
Substituting the vertex (-2,-4) in the above formula, we get;
[tex]y=a(x+2)^2-4[/tex] -------- (1)
To determine the value of a, let us substitute the point that the parabola passes through.
Hence, substituting the point (0,8) in equation (1), we get;
[tex]8=a(0+2)^2-4[/tex]
[tex]8=a(2)^2-4[/tex]
[tex]8=4a-4[/tex]
[tex]12=4a[/tex]
[tex]3=a[/tex]
Thus, the value of a is 3.
Substituting the value a = 3 in equation (1), we get;
[tex]y=3(x+2)^2-4[/tex]
Thus, the equation of the parabola in vertex form is [tex]y=3(x+2)^2-4[/tex]

Step-by-step explanation:
first find the vlumes of the different pyramids:
FORMULA:
volume = (1/3) * basearea
Cholula- 157,583,664
Cheops- 91,204,000
Answer:
The Cholula Pyramid has a greater volume.
Step-by-step explanation:
volume = (1/3) * area of base * height
In both cases, the base is a square, so the area of the base is (side)^2
volume = (1/3) * (side)^2 * height
Cholula Pyramid:
volume = (1/3) * (side)^2 * height
volume = (1/3) * (1476 ft)^2 * 217 ft
volume = 157,583,664 ft^3
Cheops Pyramid:
volume = (1/3) * (side)^2 * height
volume = (1/3) * (755 ft)^2 * 480 ft
volume = 91,204,000 ft^3
The Cholula Pyramid has a greater volume.

Elian won a sweepstakes and will receive money every week for 52 weeks. The first week, he will receive $500. Every week after that, he will receive $50 more than he received the previous week.
The amounts of money Elian receives each week form an arithmetic sequence. What is the explicit formula for the sequence?
The answer needs to be in simplified form.
Here is the explicit formula for the arithmetic sequence: an = 500 + 50(n - 1)
What does the explicit formula mean?where:
an is the amount of money Elian receives in week n
500 is the first payment
50 is the common difference
n is the week number (1-indexed)
For example, in week 2, Elian will receive $550 because 500+50(2−1)=550.
The formula is in simplified form because the common difference is a simple integer
