Answer: If I remember correctly, the answer should be <em>y=-2(3)^x. </em>
10 = ax - 3b
First, add 3b to both sides. / Your problem should look like: 10 + 3b = ax.
Second, divide both sides by a. / Your problem should look like:

= x.
Third, switch sides. / Your problem should look like: x =

which is your answer.
Answer:
Step-by-step explanation:
Let's call lifeguarding L and car washing W. In order to write a system, we need to first separate the NUMBER of hours worked from the MONEY earned, because they are very different things.
If she works 10 hours, that is the number of hours worked between both jobs. Therefore, the equation for the NUMBER of hours worked is
L + W = 10.
If she earns $13 an hour lifeguarding, the expression for that is 13L; if she earns $12 an hour car washing, the expression for that is 12W. The MONEY she earned together by doing both those jobs is
13L + 12W = 124
There you go!
Answer:
The full answer from this specific division equation is 403.58, in numeric form.
Therefore, if you multiply the quotient with the divisor, you'll get the dividend used in the equation, which is:
D. 40358
