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
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
Which representation shows y as a function of x?
(hint) its a pattern. (thats all I'll say-)

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°
solve for x: 4.72 = 3.25 + x

if the ratio of dogs to cats is 1 to 2 and there is a total of 21 animals how many are dogs
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=2yalso given that
total animals = 21
x+ y=21 putt x=2y we get2y +y =21
3y = 21
y = 7 Dogsputt y = 7 in above equation we get
x+7=21
x=14 CatsI WILL GIVE BRAINLIEST

Step-by-step explanation:
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
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
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.
