Let the number of hours worked be "h," then the total amount is 7h=91.
Answer:
If the inequality is < or >, graph the equation as a dotted line. If the inequality is ≤ or ≥, graph the equation as a solid line. This line divides the xy- plane into two regions: a region that satisfies the inequality, and a region that does not.
Answer:
x=2.98
Step-by-step explanation:
X^a/b is
. The way I memorise that is x^1/3 is the cubic root of x. Do you get it? In that case, x is raised to a power of 1 and the cubic root is practically has a power of 3.
In your example,
is practically square rooting each term then cubing them individually. Remember when square-rooting any index you halve it. I'll elaborate:
=
= 4
Then cube each,
= 64
and
=
As for the 2nd part: you must use the rules of indices.
So breaking the question up:
3 * 3 = 9
stays as is since the 2nd term does not contain x
now:
This makes your final answer look like this:
I hope that helped and good luck in your test!
