Hi there! The answer is y = -2
First we collect terms.
Now we add 3 to both sides of the equation.
Finally we divide both sides by 11.
Hence, the answer is y = - 2
a. 60(h)+40=
b 60(3)+40=
180+40=$220
c. 400=60(h)+40=
360=60(h) *divide 60 on each side*
6=h, 6 hours
Answer:
(2, 12)
Step-by-step explanation:
You do it by adding
2 and 0.
4 and 8.
9 to the 4th power is 6561
Answer:
x²-4x+7
-x²-6x-12
Step-by-step explanation:
1.) the first thing we do is expand the exponent (or mulitply (x-2)(x-2) the images below will show you how to do that
We get x²-4x+4 and then just need to add three
x²-4x+7
2.)
We do the same thing (expand the exponent) and get x²+6x+9
which means so far we have
-(x²+6x+9)-3
carry out the negative sign and subtract 3
-x²-6x-12
