Answer:
y=-3x+3
Step-by-step explanation:
your y in your points in the b in y=mx+b because it's the y intercept and then the slope is -3
To find out how tall the student is you have to divide 28 by 5 to get 5.6. So the student can not be any taller than 5 feet 6/10 in.
the shorter sides are 4 inches and the longer sides are 21 inches long
Answer:
Not proportional.
Step-by-step explanation:
Given ratios:
To tell whether the ratios are proportional or not.
Solution:
In order to tell whether the given ratios are proportional or not, we will reduce the fractions to the simplest numbers by dividing the numerator and denominator by their greatest common factor and then comparing them. If they are equal then the ratios are proportional else not proportional.
So, the simplest form of can be calculated by dividing both by 2 as it is the G.C.F.
the simplest form of can be calculated by dividing both by 2 as it is the G.C.F.
Now, since , hence the ratios are not proportional.
Answer:
Assuming you want to simplify the expression, it can be shortened to:
-k² - 2k
Step-by-step explanation:
What you need to do here is called grouping like terms. Like terms can be described as terms that have the same factors. In this case, the factors we're looking at are k and k²:
Given:
k - 3k² -3k + 2k²
We'll rearrange to group like expressions:
= -3k² + 2k² + k -3k
Pull out common factors:
= (-3 + 2)k² + (1 - 3)k
And simplify:
= -k² - 2k
