Answer:
Step-by-step explanation:
value of 4, and you want to square it or exponent 2
so 4^2 = 4x4
=16
What is ^-2
It does the same operation however because to is negative it really means putting 4 in the denominator so 2 becomes positive. Inverse of the exponent 2
1/4^2 is the same as 4^-2
which will both give 1/16
Answer:
Step-by-step explanation:
3 2/5 minus 1/2 after finding common denominator.
Answer:
29/10
Then simplify
Answer:
<em>m</em> = 6
Step-by-step explanation:
Slope Formula: 
Simply choose 2 points and plug them into the formula to find slope<em> m</em>:
(1, 20)
(2, 26)


<em>m</em> = 6
Equations:
4x - 2y = 12
-4x - 9y = 54
Multiple them in both sides
4x - 2y - 4x - 9y = 12 + 54
-2y - 9y = 66
-11y = 66
y= -6
If y= -6 then put y in first or second equation.
I put it in first equation
4x - 2.(-6) = 12
4x + 12 = 12
x= 0
Therefore
(x,y) = (0, -6)
