Answer:
Step-by-step explanation:
-6=x/6
Multiplying both sides by 6 we get:
6(-6)=(x/6)6
-36=x OR x=-36
Answer:
x=10
y=5
Step-by-step explanation:
Plugin 2y for x in the first equation.
you will get -4(2y)+11y=15
then you have -8y+11y=15
3y=15
y=5
x=2y, so x=10
<span>Break down every term into prime factors. ...Look for factors that appear in every single term to determine the GCF. ...Factor the GCF out from every term in front of parentheses, and leave the remnants inside the parentheses. ...<span>Multiply out to simplify each term. thats it

Continuous interest is Pe^(rt), but you are doubling your money in nine years so you want 2P=Pe^9t. Now divide both sides by P so 2=e^9t. Now take the ln of each side so ln2=9t. then just divide by 9. You will get a decimal, so move the decimal two places to the right to get your interest rate.
Answer:
Step-by-step explanation:
From B on the ground straight up to A and then turn the corner to follow the dotted line...that is a 90 degree angle. So in order to find the angle of depression, subtract 66 from 90 to get 24 degrees. Subsequently, that is also the angle of elevation (the base angle inside the triangle) due to parallel lines and whatnot.
