Answer:
A. (-3,1)
Explanation:
if you invert the point over the Y-axis, then it will switch the x point to negative.
Answer: 18
Step-by-step explanation:
Square root of 81 is 9 because 9*9=81 then 9*2=18
Answer:
The answer is 1/9.
Step-by-step explanation:
Using the equation a-b=2, we can solve that a = 2+b.
We can then <u>substitute that into the expression</u> given to get 3^b/3^(2+b).
Since <u>they have the same base, we can subtract the exponents from the numerator and denominator</u> to get 3^(b-2-b) which <em>simplifies to 3^-2.</em>
3^-2 is simply 1/9.
Answer:
D 1 and -1
Step-by-step explanation:

divided by 8

(x+1)(x+1)=0
so x=+-1
Answer:
We have the equation:
(14 N/mm)*X = Y N/cm
So we want to transform 1/mm to 1/cm.
We know that:
10mm = 1cm
1 = 10mm/1cm (we want to have mm on the numerator, so it cancelates with the mm in the denominator)
then the conversion is from 1/mm to 1/cm is:
X = 10mm/cm
then we have:
(14N/mm)*(10mm/cm) = 140 N/cm
