Answer:
y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))
Step-by-step explanation:
Solve for y:
-4 y^2 - 3 x y + x^2 = 0
Hint: | Multiply both sides by a term to make the coefficient of y^2 positive.
Multiply both sides by -1:
4 y^2 + 3 x y - x^2 = 0
Hint: | Using the quadratic formula, solve for y.
y = (-3 x ± 5 sqrt(x^2))/8:
Answer: y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))
The perimeter of your closet is equal to 18 feet. The difference of the length and the width equals 1 foot. Write a system of linear equations which represent the perimeter of your closet in respect to its width (x-axis) and length ( y-axis), and solve the system by graphing.
9514 1404 393
Answer:
length: y = 5
width: x = 4
Step-by-step explanation:
The perimeter is twice the sum of length and width:
P = 2(L+W)
18 = 2(y +x) . . . . . using the given values
The difference in dimensions can be expressed as ...
y -x = 1
When the above two equations are graphed, we see the solution is ...
(x, y) = (4, 5)

17 = − 13 − 8 x
Show your steps Please :3
Answer:
x = 3.75 or [tex]3\frac{3}{4}[/tex]
Step-by-step explanation:
17 = -13 - 8x
add 13 to both sides
17 + 13 = -13 + 13 + 8x
30 = 8x
divide both sides by 8
30/8 = 8x /8
3.75 = x
The low temperatures in two cities are being compared. In City 1, the range in temperature is 20°F and the IQR is 7°F.
In City 2, the range in temperature is 15°F and the IQR is 7°F.
What might you conclude about the cities based on the ranges and interquartile ranges?
B.The weather pattern in City 2 is more consistent than the weather pattern in City 1
explanation:
Range and interquartile range (IQR) measures the spread of data. Range measure the overall spread and IQR measures spread in 50% of data.
Range is calculated by differencevof maximum and minimum value whereas IQR is calculated by difference of First quartile and third quartile.
Since, the range and IQR is less for City 2 as compared to City 1.
Thus ,weather pattern of City 2 is more consistent as compared to City 1.

C. x-1
D. x-3
Answer:

Step-by-step explanation:
X-9y=17 find y (use integers or fractions for any numbers in the expression)
Let's see what to do buddy...
_________________________________
[tex]x - 9y = 17[/tex]
Subtract the sides of the equation minus x
[tex] - 9y = 17 - x[/tex]
Divided the sides of the equation by -9
[tex] \frac{ - 9}{ - 9}y = \frac{17 - x}{ - 9} \\ \\ [/tex]
[tex]y = \frac{ - (17 - x)}{9} \\ [/tex]
[tex]y = \frac{x - 17}{9} \\ [/tex]
_________________________________
And we're done.

angle a and b are supplementary angles. angle where a = 30+2x and b =x what is the measure of b degress
Answer:32 times 4 - 8 in degrees
Step-by-step explanation:
Since b = x, hence the value of b is 30 degrees
For two angles to be supplementary, the sum of the angles must be equal to 180 degrees
Given the angles
a = 30 + 2x
b = x
Equating the sum to 180
a + b = 180
30+2x + x = 180
30 + 3x = 180
3x = 180 - 30
3x = 150
x = 30 degrees
Since b = x, hence the value of b is 30 degrees

Parallel lines have same slope
Given line, in slope intercept form
2x - 3y = 03y = 2xy = 2/3xParallel line is
y = 2/3x + bUsing point (5, 4) to find b

A right rectangular prism is packed with cubes of side length fraction 1 over 5 inch. If the prism is packed with 15 cubes along the length, 6 cubes along the width, and 5 cubes along the height, what is the volume of the prism? (1 point) Group of answer choices A. Fraction 2 and 3 over 10 cubic inches B. Fraction 3 and 3 over 5 cubic inches C. Fraction 7 and 1 over 5 cubic inches D. Fraction 7 and 1 over 10 cubic inches
Given:
A right rectangular prism is packed with cubes of side length [tex]\dfrac{1}{5}[/tex] inch.
Prism is packed with 15 cubes along the length, 6 cubes along the width, and 5 cubes along the height.
To find:
The volume of the prism
Solution:
Side length of each cube [tex]=\dfrac{1}{5}[/tex] inch.
15 cubes along the length, so length of prism is
[tex]l=15\times \dfrac{1}{5}=3\text{ inches}[/tex]
6 cubes along the width, so width of prism is
[tex]b=6\times \dfrac{1}{5}=\dfrac{6}{5}\text{ inches}[/tex]
5 cubes along the height, so height of prism is
[tex]h=5\times \dfrac{1}{5}=1\text{ inch}[/tex]
Now,
Volume of rectangular prism is
[tex]V=l\times b\times h[/tex]
[tex]V=3\times \dfrac{6}{5}\times 1[/tex]
[tex]V=\dfrac{18}{5}[/tex]
[tex]V=\dfrac{3\times 5+3}{5}[/tex]
[tex]V=3\dfrac{3}{5}\text{ cubic inches}[/tex]
Therefore, the correct option is B.

Answer:
The equation is y = 12.5x I believe.
Answer;
The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.
The equation is
y = 12.5 × t
Explanation:
To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:
For example
25
miles
÷
2
hours
=
12.5
miles
hour
A direct proportionality will always result in an equation that resembles this:
y = k x where y and x are the related quantities and k is the constant of proportionality. If you draw a graph using the values you have, the graph will show a straight line the passes through the origin. The slope of this line will be the constant of proportionality. And if the values given are real physical quantities, this constant will contain important information about the situation you are studying.
Rachel and four friends were going to the movies. Each ticket cost $11 and then they bought 2 popcorns at $3.75 each, and they each bought their own soda at $2.75 each. How much money did they spend total for their trip to the movies? If they decide to split the bill, how much will they each pay?
Answer:
Total amount spent [tex]=\$73.5[/tex]
If they decide to split the bill, amount paid by each of the person [tex]=\$15.25[/tex]
Step-by-step explanation:
Cost of each movie ticket = $11
Cost of 5 tickets = 5(11)= 55
Cost of each packet of popcorns = $3.75
Cost of two packets of popcorns = $2(3.75) = $7.5
Cost of each soda = $2.75
Cost of five sodas = $5(2.75) = $13.75
Total number of persons (Rachel and four friends) = 5
Total amount spent [tex]=11(5)+2(3.75)+5(2.75)=55+7.5+13.75=\$76.25[/tex]
If they decide to split the bill, amount paid by each of the person = [tex]\frac{76.25}{5}=\$15.25[/tex]

The number of burritos Delainy ate on Tuesday is the same as the number of burritos Louie ate on Wednesday. On Tuesday, Delainey ate 16 more than 1/2 the total number of burritos consumed. On Wednesday, Louie ate 1 less than 3/4 of the total number of burritos consumed. Write an equation to determine the total number of burritos consumed. Hint: let x = # burritos consumed.
Answer:
The total number of burritos consumed is 68 and an equation to determine the total number of burritos consumed is [tex]\frac{1}{2}x+16=\frac{3}{4}x-1[/tex]
Step-by-step explanation:
Let x be the total number of burritos consumed
We are given that On Tuesday, Delainey ate 16 more than 1/2 the total number of burritos consumed
So, Number of burritos ate by Delainey on Tuesday=[tex]\frac{1}{2}x+16[/tex]
We are also given that Louie ate 1 less than 3/4 of the total number of burritos consumed.
So, Number of burritos ate by Louie on Wednesday =[tex]\frac{3}{4}x-1[/tex]
We are given that The number of burritos Delainy ate on Tuesday is the same as the number of burritos Louie ate on Wednesday.
So, [tex]\frac{1}{2}x+16=\frac{3}{4}x-1\\1+16=\frac{3}{4}x-\frac{1}{2}x\\17=\frac{x}{4}\\68=x[/tex]
Hence the total number of burritos consumed is 68 and an equation to determine the total number of burritos consumed is [tex]\frac{1}{2}x+16=\frac{3}{4}x-1[/tex]

Answer: y=8 m=5
Step-by-step explanation:
Answer:
1. 3.125
2. 4.5
Step-by-step explanation:
1. Since the figures are similar, the number you divide from one triangle to the other is the same, no matter the side length. 5(x) = 8 so 5/x = y. If x = 1.6, then y equals 3.125.
2. The same thing here. 4/x = 3 and 6/x = m. In the first equation x would be 1 1 1/3. 6/ 1 1/3 is the same as 6 x 3/4 which is 18/4 or 4.5.

Marcus is rewriting a polynomial by combining like terms
What is polynomial?Polynomial equation is equation of independent variables.
Here, questions seems to be incomplete.
In polynomial, it can be of maximum endless number of term or minimum 1 term. Marcus can add any number or repeat any number. And if he revised the old number than the number could be -3mn^3 and -5mn^3.
Thus, Marcus has to add -3mn^3 and -5mn^3 to complete the polynomial.
