Answer:

A, C, D

Step-by-step explanation:

In a proportional relationship, y = kx, k is the constant of proportionality.

A)

4y = x

y = 1/4 x

k = 1/4      Yes

B)

y = 4x

k = 4      No

C)

32y = 8x

y = 8/32 x

y = 1/4 x

k = 1/4    Yes

D)

y = 0.25x

k = 0.25 = 1/4     Yes

E)

1/4 y = 2x

y = 4 * 2x

HELP ASAP!!!!<br> GIVING BRAINLIEST!<br><br> Find the value of x and y with the steps PLEASE.
PtichkaEL [24]

Answer:

x=70

y= 40

Step-by-step explanation:

the triangle containing x is an isosceles triangle so two of the sides are 55.

55+55+x=180.

110+x=180

110-110+x=180-110

x=70

Triangle BAC is equilateral so 180/3=60. Now

x+60+c=180

70+60+c=180

130+c=180

130-130+c=180-130

c=50

That gives us one corner of triangle CBD. We know a second angle is 90 so

50+90+y=180

140+y=180

140-140+y=180-140

y=40

I think that is correct but you are free to check it yourself
