Answer:
y+7=25(x+4)
Step-by-step explanation:
It is + because remember two - - negatives make a positive +. And the original formula is like this y-y=m(x-x), then m represents the slope, so your slope will always go in place of the m. And you can number the it y one - y two = m (x one - x two) if that helps. Hope it did help!!!
The midpoint is: (-4.5,8.5)
Given:
A number is 400.
To find:
The additive inverse of 400.
Solution:
We know that the sum of a number and its additive inverse is 0.
If "a" is number and "b" is its additive inverse, then

Let x be the additive inverse of 400. Then,

Subtract both sides by 400.


Therefore, the additive inverse of 400 is

Answer:
hi
Step-by-step explanation:
first of all,we should do this:
1 year is 12 month
amd 4 year is 48 month(12×4)
then we must add 2 months (wich is given) to 48
He was 50 months old when he started school
and we should find how old is he now
11 ×12=132months
132+1=133months
133-50=83 ( he has been 83 months in school)
let's turn it to years 6 years 11 months
( for finding years you should divide 83 to 12)
hope it helps
