Which two quantities are in a proportional relationship, and why?

Answers

Answer:

[tex]\frac{3}{4} =\frac{18}{24}[/tex] The ratios are the same .

Step-by-step explanation:

When  y ∝ x then,

[tex]y=k*x[/tex]

When y ∝ 1/x then

[tex]y=\frac{k}{x}[/tex]

while k is a constant.

Answer:

3/4 and 18/24; the ratios are the same.

Step-by-step explanation:

A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "three is to four as eighteen is to twenty-four."

In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

Here, 3 and 24 are the extremes, and 4 and 18 are the means. Since the cross products are both equal to 60, we know that these ratios are equal and that this is a true proportion.

a. 5/9 or 11/18

b. 3/8 or 4/9

Answers

Answer:

for a it would be 11/18 and for b it would be 4/9

Step-by-step explanation:

This is because I did the same butterfly method. 5 times 5 times 18 which is 90 for 5/9 and 9 times 18 is 99 for 11/18, you can also write it as 5/9 and 11/18 but cross multiply. This is also what I did with the second one.

b, the smaller the number the bigger the fraction.

Reposting question because I didn't get the correct answers last time, Write an equation of the line in slope-intercept form. picture attached

Answers

Answer:

I think y=1x+2

Step-by-step explanation:

y=mx+c

m=(y2-y1)/(x2-1)

I just chose (0,2) and (-3,-1)

-1-2=-3

-3-0=-3

-3/-3=1

y=1x+c

c= y-intercept and (0,2) is the y-intercept so

y=1x+2

I think

Y=1x+2
Because 1 is the slope and 2 is the y intercept
