Find Midpoint of (-2,3) and (1,8)
------------------------------------------------------------------------------------
Easy
just remember
you can do ANYTHING to an equaiton as long as you do it to both sides
try to get place holder by itself
4.5b+9=90
minus 90 from both sides
4.5b+9-9=90-9
4.5b+0=81
4.5b=81
either divide both sides by 4.5 or double 4.5 to get rid of the decimal
I will double
double both sides
9b=162
divid both sides by 9
b=18
Answer:
Step-by-step explanation:
We are required to simplify the quotient:
Since the <u>numerator and denominator both have the same root index</u>, we can therefore say:
The simplified form of the given quotient is .
Answer:
f(4) = 85.
Step-by-step explanation:
When you substitute the 4 into the x and solve for f(4), all that means is that every x in the equation becomes 4. There's only one on the right side: the 18x. This becomes 18*4, or 72, which is then added to 13, to get 85.
