Answer:
Option A
Step-by-step explanation:
We know that for an eqn. 
, the quadratic formula is =
So using quadratic eqn. for 
1b the older the child is the more it cost to raise them
2 there is a relationship. The higher the age the less the price is.
3a there si no relationship because the points don’t have a pattern and are all over the plot.
3b it is not reasonable bc there is no obvious correlation between the completely unrelated shoe size and reading scores.
X=2+5y
x-y=30
basically, all you're doing here is solving a system of equations. use the second equation to find out what x or y means. i'm going to solve it for x.
this is the new equation : x=30+y
now i plug this equation into the first one.
30+y=2+5y
30=2+5y-y
30=2+4y
28=4y
y=7
now that you know what y is, take that second equation we did in the beginning and plug in y.
x-7=30
solve for x
x=37
the two integers are 37 and 7.
Answer:
21 1/6 ft
Step-by-step explanation:
Add the lengths together
12 1/2 + 8 2/3
Get a common denominator of 6
12 1/2 *3/3 + 8 2/3 *2/2
12 3/6 + 8 4/6
20 7/6
20 +6/6+1/6
21 1/6
