Answers

Answer 1

Answer:

Answer:

The equation is y=-3x-2

Step-by-step explanation:

The first we need to know is the equation of a line, and it is y=mx+b

where the m is the slope and b is the interception to the y axis

With the information in the question the slope is -3 and the equation thats equal to m. and the y intercept of -2 thats equal to the b value

then y=-3x-2

Find y when x=15 if y=6 when x=30

Answers

y=kx
6=k (30)
6/30=k(30)/30
.2=k
y=.2(15)
y=3
So y is 3.

Y = 12 because you multiply x by two to get x2, which is 30, and multiply y by two to get 12 - this is wrong, the answer is three, i did the math backwards

Answers

If this is what your talking about this is your answer:

The batch of fruit salad has an equal amount of apples and cherries. This is because there are 1 1/2 c of apples and 1 2/4 c of cherries. the 1 1/2 is already simplified but the 1 2/4 is not. 1 2/4 is the same as 1 1/2, therefore apples and cherries have equal amounts.
