20 POINTS FOR HELP!!

Y=3x+30
because if you look she automatically makes $30, and her salary goes up every time cone by 3<span />

4 0
So since the first point (0,30) has an x intercept of 0 and a y intercept of 30
We can immediately eliminate any that do not have an y intercept of 30
So choices a and b are automatically incorrect

and now to solve for slope we do (y2-y1)/(x2-x1)
so we can choose any two points so I'll use points (0,30) and (1,33)

so 33-30=3
and 1-0=1

so we then do rise(y) over run (x)
and we now know our unit rate is 3x

so your answer is D

Jordan's recipe calls for 3 cups of flour and 2 cups of water. what is the ratio of flour to water? if jordan wants to triple hi
allochka39001 [22]
You would multiply the cups of flour by 3 and the cups of water by 3. which would give you 9 cups of flour and 6 cups of water. the ratio is 1.5 cups of flour to 1 cup of water.

Please write answers to the questions that are in the image.
marishachu [46]

Answer:

To find part A you need to find common denominator.

1/3 + 3/5=

5/15 + 9/15= 14/15

His mistake for a is that he didn't find the common denominator and that he just added the fraction as it is. So the corrected version would be 14/15.

To find part B you also need to find the least common denominator.

11/12-5/6=

11/12-10/12=1/12

His mistake was that he didn't find the least common denominator and he subtracted the fraction as it is. The answer corrected would be 1/12.
