Here is the graph for one equation in a system of equations:


Match the correct equation to the scenario.

Write a second equation for the system so it has infinitely many solutions.

a) y=-3/4x+4

b) y=-3/4x+2

c) y=-3/4x+1

Write a second equation whose graph goes through (0, 1) so the system has no solutions.

a) y=-3/4x+4

b) y=-3/4x+2

c) y=-3/4x+1

Write a second equation whose graph goes through (0, 2) so the system has one solution at (4, 1).

a) y=-3/4x+4

b) y=-3/4x+2

c) y=-3/4x+1

Answers

Answer:

Step-by-step explanation:

1. y = -3/4 +4 cause that is the same line as the equation and since they are the same line it would mean there would be infinitely many solutions.

2. y=-3/4x+2 if you graph this line next to the orginal line it runs through (0,1) and you can see that its paralellel and will never meet the other line so there will be no solutions

3. for this question im confused because none of the answers fits the line that the question is asking for the closest would be y= -3/4x+2 since it runs through (0,2) but other than that none of the answers fit the line its describing.

an equation that would work though would be y=-1/4x+2

Gio baked 21 cupcakes for the holiday sale. He made some with vanilla icing, and some with mint-chip icing. He charged $2 for the vanilla cupcakes, and $4 for the mint-chip cupcakes and made $54. How many of each did he make? He created the following system of equations to find out how many of each he made. Let x represent the number of vanilla cupcakes, and y represent the number of mint-chip cupcakes.
x+y=21

2x+4y=54

Answers

15 vanilla and 6 mint chip

$2(15) + $4(6) = $54

Answer: 15 vanilla and 6 mint

Step-by-step explanation:

You would solve for x and get x=21-y and then plug that into the next equation and get 2(21-y)+4y = 54.

You would then solve for y.

42-2y + 4y = 54

42+2y =54

Then subtract 42 from both sides.

2y = 12, and then divide by 2.

You get y=6.

Then we know we sold 21 cupcakes so

21-6=x

15=x

You will need 120 feet of fencing to put all the way around a rectangular garden. The length of the garden is 40 feet. What is the width?


A. 20 feet


B. 40 feet


C. 4,800 feet


D. 80 feet

Answers

Answer:

A. 20 ft

Step-by-step explanation:

(120/2)-40=20

Answer:

a) 20 feet

Step-by-step explanation:

We know it's a rectangle so lengths are the same and widths are the same

If length is 40

That would mean 120-2(40) = 80

We know 2 widths of a rectange so 40/2 is 20

Therefore 20 feet.

if the ratio of dogs to cats is 1 to 2 and there is a total of 21 animals how many are dogs

Answers

Answer:

Step-by-step explanation:

Let   cats = x  and dogs = y

and given conditions are ,

dog: cat= 1:2

y:x=1:2

y/x = 1/2

x=2y

also given that

total animals = 21

x+ y=21     putt x=2y we get

2y +y =21

3y = 21

y = 7  Dogs

putt y = 7 in above equation we get

x+7=21

x=14 Cats
There are 7 dogs and 14 cats

Every one dog there are two cats 1:2
Also could be written as (cats) 7:12 (dogs)

Answers

Answer:

27°

Step-by-step explanation:

XWY and VWY are supplementary

∴ XWY + VWY = 180°

∴ XWY = 180° - VWY

XYW and ZYW are supplementary

∴ XYW + ZYW = 180°

∴ XYW = 180° - ZYW

ΔXWY is a right triangle at X

∴ XWY + XYW = 90°

∴ 180° - VWY + 180° - ZYW = 90°

∴ 180° - 6x + 180° - 4x = 90°

∴ 360° - 10x = 90°

∴ 10x = 270°

∴ x = 27°
