Answer:
y=(-5/2) x -7
Step-by-step explanation:
y=mx+b
m=(-5/2)
To find b:
3=(-5/2)times"x" + b
3=(-5/2)times(-4) + b
3= 10 +b; b=-7
y=(-5/2) x -7
For this case, the first thing we must do is define variables.
We have then:
x: number of years
y: total salary
For company 1 we have:

For company 2 we have:

By the time both salaries are equal we have:

From here, we clear the value of x.
We have then:


Answer:
Brenda's salary would be the same with both companies in 8 years.
Answer: y = 5/2x -2
Step-by-step explanation:
parallel = same slope so the slope of the new line is 5/2
y+2 = 5/2(x-0)
y = 5/2x -2
Answer:
Slope is 2.
Step-by-step explanation:
So to find slope, we need to take the change in the y value, and the change in the x value, and then divide them. This may be confusing, so here is just 3 formulas in 3 seperate steps that we use to find it:
Step 1 - 
Step 2 - 
Step 3 - 
So lets start by doing step one.
All we need is to look for two x values. Lets use 5 and 6:
6-5=1
So 1 is our change of x. This is our 1st step.
Next we can use 2 y values, note that these should be the 2 y values that go wiht the x values above. So this means we have to use -3 and -1:
-1-(-3) = 2
So 2 is our change in y. This is our 2nd step.
Now lets plug this into:
:

So our slope is 2. Completing our 3rd and final step.
Hope this helps!
For this case, what you must do is to graph both functions in the same coordinate plane and verify where they are cut.
The points where they are cut will be solutions for f (x) = g (x).
This particular function is cut into two points:
(0, 2)
(1, 3)
Therefore, the solution for f (x) = g (x) is
x = 0
x = 1
