b^-2-x^-2/b^-1+x^-1
b^-2/b^-1=b^-1
x^-2/x^-1=x^-1
As a result, the simplest form is:
b^-1-x^-1. Hope it help!
We have that
<span>y=3x</span>²<span>+18x-21
using a graph tool
see the attached figure
the solutions are
x=-7x=1</span>
Yes, both angles are acute because all complementary angles are acute.
Answer:
y ≤-7
Step-by-step explanation:
-8y ≥56
Divide each side by -8. Remember to flip the inequality
-8y/-8 ≤56/-8
y ≤-7
