Answer:
No solutions.
Step-by-step explanation:
y = 5/2x + 2
2y = 5x + 8
Plug the first equation into the second.
2(5/2x + 2) = 5x +8
5x + 4 = 5x + 8
5x + 4 cannot equal 5x + 8, so this system of equations has no solutions.
A telephone company charges a fixed monthly rate plus a rate per megabyte of data used. The company charges $155 for 100 megabytes and $245 for 200 megabytes. An equation can be written to show the relationship between the total megabytes of data used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph? Draw a graph that joins the points (155, 100) and (245, 200) and has a slope = 0.9 Draw a graph that joins the points (155, 100) and (245, 200) and has a slope = 1.1 Draw a graph that joins the points (100, 155) and (200, 245) and has a slope = 1.1 Draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 0.9
Answer:
Draw a graph that joins the points (100, 155) and (200, 245) and has a slope = 0.9
Step-by-step explanation:
x variable represents total megabytes of data used
y variable represents total monthly charges
The company charges $155 (y) for 100 megabytes (x) means that the point (100, 155) belongs to the equation.
The company charges $245 (y) for 200 megabytes (x) means that the point (200, 245) belongs to the equation.
With these two points, the slope is computed as follows:
(245 - 155)/(200 - 100) = 0.9
Answer:
the correct answer is
Step-by-step explanation:
Second option: Draw a graph that joins the points 100 and 135 500 and 375 and has a slope of 0.6
or if you have the other problem its
Draw a graph which joins the points (100, 120) and (50, 95) and has a slope = 0.50

In Social Studies this year we learned a lot of things like Panama and the Canal. One of the favorite things that I learned this year is The Reconstruction Era. In that lesson, we learned that The Reconstruction era was the period after the American Civil War from 1865 to 1877 and the purpose of the Reconstruction was to help the South become a part of the Union again. My favorite lesson that we learned was How American Indians Viewed Their Environment. That was my favorite lesson because we learned that the natives believed that each part of nature had its own spirit and each person had to maintain a balance with these spirits. In conclusion.......

Use △XYZ, in which ∠X is a right angle and tanY=815.
Answer:
8/17
Step-by-step explanation:
The correct and complete question is:
Use △XYZ, in which ∠X is a right angle and tanY=8/15. What is the ratio for sinY?
From definition:
tan(Y) = opposite/adjacent
From the graph and the question:
tan(Y) = XZ/XY = 8/15
Then:
XZ = 8 and XY = 15. Using pytaghorean theorem:
XZ² + XY² = YZ²
8² + 15² = YZ²
√289 = YZ
17 = YZ
From definition:
sin(Y) = opposite/hypotenuse
From the graph:
sin(Y) = XZ/YZ
sin(Y)= 8/17

40
Step-by-step explanation:
If you are given a rectangular home and a square swimming pool, with dimensions of Pool = 2x & home = (2 +5x) & (3+10x) The total amount of fencing they need can be written as x + 10. If x = 5; The family needs 5 yards of fencing for their home. The family needs 10 yards of fencing for their pool.
may I have brainliest?
The family needs 40 yards of fencing for the pool and 160 yards of fencing for the home.
PerimeterThe perimeter of a rectangle is:
Perimeter = 2(length + width)
For a square:
Perimeter = 4 * length
From the diagram:
Perimeter of pool = 4 * 2x = 8x
Perimeter of rectangle = 2(3 + 10x + 2 + 5x) = 30x + 10
Total amount of fencing = 8x + 30x + 10 = 38x + 10
x = 5. hence:
Perimeter of pool = 8(5) = 40 yards
Perimeter of home = 30(5) + 10 = 160 yard
The family needs 40 yards of fencing for the pool and 160 yards of fencing for the home.

Find the volume of the solid shown or described. If necessary, round to the nearest tenth. What is the volume of the shed?
Answer:
Option (B)
Step-by-step explanation:
Given shed is a composite figure having a rectangular solid at the base and a triangular prism on the top.
Volume of the shed = Volume of the rectangular prism + Volume of the triangular prism
Volume of the rectangular prism = length × width × height
= 5 × 2 × 3
= 30 m³
Volume of the triangular prism = Area of the base × height of the prism
= [tex]\frac{1}{2}(\text{Base})(\text{height of the triangular bsae})[/tex] × height of the prism
= [tex][\frac{1}{2}(5)(1.6)]\times 2[/tex]
= 8 m³
Volume of the shed = volume of the rectangular prism + volume of the triangular prism
= 30 + 8
= 38 m³
Therefore, Option (B) will be the answer.

PLEASE HELP!! Solve system of equations
I think you use desmos but mine isn’t working
Answer:
The solution of system of equations is (1 , 5)
Step-by-step explanation:
The first equation is:
3y + 2x = 17
The second equation is:
-x - 4y = -12
3y + 2x = 17 :
For x = 0 , y = 5.67
For x = 1 , y = 5
For x = 2 . y = 4.33
For x = 3 , y = 3.67
For x = 4, y = 3
-x - 4y = -21 :
For x = 0 , y = 5.25
For x = 1 , y = 5
For x = 2 . y = 4.75
For x = 3 , y = 4.5
For x = 4, y = 4.25
Solve the system of Equations:
3y + 2x = 17 ⇒ a
-x - 4y = -21 ⇒ b
Multiply equation b by -1:
x + 4y = 21
Rearrange:
x = 21 - 4y
Substitute x into equation a:
3y + 2(21-4y) = 17
3y + 42 - 8y = 17
-5y = 17 - 42
-5y = -25
y = 5
Substitute y in equation b:
-x - 4(5) = -21
-x -20 = -21
-x = -21+20
-x = -1
x = 1

The square based pyramid is cut horizontally at a height of 15cm to leave this frustum. Calulate the volume of the frustum.
Answer:
The answer is given below
Step-by-step explanation:
The question is not complete. The correct question is:
A square based pyramid have a height of 30 cm and base of 10 cm. The The square based pyramid is cut horizontally at a height of 15cm to leave this frustum.
Answer:
The frustum would have a base of 10 cm and height of 15 cm. The lower base has a length of 10 cm. to calculate the upper base, we use the formula:
[tex]\frac{height\ of\ frustum}{height\ of \ pyramid}=\frac{base \of\ upper\ edge}{base \of\ lower\ edge}[/tex]
Substituting:
[tex]\frac{30}{15}=\frac{10}{b} \\ b=15*10/30=5[/tex]
The volume of the frustum is given by the formula:
[tex]V=\frac{h}{3}(A_1+A_2+\sqrt{A_1A_2} )[/tex]
Where h is the height of the frustum = 15 cm, A1 is the area of the lower base = 10 * 10 = 100 cm², A1 is the area of the upper base = 5 * 5 = 25 cm²
Substituting gives:
[tex]V=\frac{h}{3}(A_1+A_2+\sqrt{A_1A_2} )=\frac{15}{3}(100+25+\sqrt{100*25} )= 875\ cm^3[/tex]

Answer: x = 3, y = -2 → (3, -2)
Step-by-step explanation:
Using Elimination Method, multiply the equations by a number that allows the coefficients of either x or y to be the same number with opposite signs. Then add the two equations to solve solve for the remaining variable.
I choose to eliminate x:
2x - 5y = 16 --> 3(2x - 5y = 16) --> 6x - 5y = 48
3x + 2y = 5 --> -2(3x + 2y = 5) --> -6x - 4y = -10
-19y = 38
÷19 ÷19
y = -2
Next, substitute y = -2 into either equation to solve for x.
I choose the 1st equation:
2x - 5y = 16
2x - 5(-2) = 16
2x + 10 = 16
2x = 6
x = 3
Check your answer by inputting x = 3 and y = -2 into the other (2nd) equation:
3x + 2y = 5
3(3) + 2(-2) = 5
9 + -4 = 5
