Answer:
h(9)=62
Step-by-step explanation:
h(x)=8x-10
62=8x-10 <em>(</em><em>+</em><em>1</em><em>0</em><em>)</em>
72=8x <em>(</em><em>÷</em><em>8</em><em>)</em>
9=x
Answer:
12x(2x2^3)=120
Step-by-step explanation:
12x2+2^3=120
(12x2)+2^3=32
12x(2+2^3)=?
12x(2+8)=?
12x10=120
- I’m assuming the expression implies the following:
(1-n)/(n^2 - 1)
The steps goes as follows:
= -(n-1)/(n^2-1) (factored a negative out)
= -(n-1)/[(n+1)(n-1)] (Factored denominator into a difference of squares, but don’t just blindly accept the fact, expand it and you should get the original denominator)
At this point, the (n-1) terms cancel, as you should know: a real number, besides 0, over itself is 1.
= -1/(n+1) , which is the answer
Note: You could also see it as 1/-(n+1) or 1/(-n-1)
Yes, it is a linear equation.
