Answer:

Step-by-step explanation:
You will use the FOIL method, which is very similar to the distributive property.
In order to do multiply correctly, multiply the y by 3x, 5y, and -2. You should get:

Then multiply the -4 by 3x, 5y, and -2 where you should get:

By using the foil method, you got rid of the parentheses. Now you can simply combine like terms and get your final answer:

Answer:
(-4, -7) (-3, 5) (1, 3) (9, 19)
Step-by-step explanation:
Plug in the values of x (the domain numbers) into the equation to solve for the range values (y)
For example, for the x value of -4
y= 2(-4)+1
y= -8+1
y= -7
Answer:
4 + 2/3 hours
Step-by-step explanation:
For the expert,
6 hours = 1 job
For the secretary,
7 hours = 1 job
We want to figure out how much the expert gets done in 2 hours.
2 hours = x jobs for the expert.
To turn 6 hours = 1 job into this, we can multiply both sides of the equation by 2 (the number we want to get to) / 6 (the number we are at) to get
6 hours * 2/6 = 1 job * 2/6
2 hours = 2/6 jobs
Therefore, the expert does 2/6 of the job, and 1-2/6 = 4/6 of the job is left for the secretary. We want to figure out how long it takes for her to complete the job
We know
7 hours = 1 job
and want to figure out
y hours = 4/6 jobs
We can multiply both sides of the original equation by (4/7) (the number we want to get to) / 1 (the number we are at) to get
7 hours * 4/6 = 1 job * 4/6
28 /6 hours = 4/6 jobs
= 4 + 4/6 hours
= 4 + 2/3 hours
