<u>Using mental math to find the slope of the line:</u>
If you think about the formula, then you set up the points in your head, you will notice that the first point is on top of the second point. And that way makes it easy to simplify. All you would need to do is subtract down in your head: For example:
(0, 0)
(4, 8)
As you can see, the first point is on top of the other, and that way you can just subtract from bottom to top. If you do it that way, it is set up (Remember, you would do this all in your head)
Y = -2x - 4
-2x is the slope and -4 is the y intercept.
Answer:
y = (2/5)x + 2
Step-by-step explanation:
To find the inverse of a function, we simply exchange the variables x and y and solve for y.
For this function we will write it as such:
y = -5 + (5/2)x
So to find the inverse, we will swap the x and y and solve.
y = -5 + (5/2)x
x = -5 + (5/2)y
x + 5 = (5/2)y
(2/5) * (x + 5) = y
(2/5)x + (2/5)5 = y
(2/5)x + 2 = y
Thus the inverse of the function is:
y = (2/5)x + 2

Answer:
$1050.00
Step-by-step explanation:
17500 + 6% (1050.00) =18550
The width of the new enlarged box should be 5 inches. 6/1=30/× Then cross multiply so... 6 time x=6x and 30 times 1=30.(30=6x) Finally, 30 divided by 6 equals 5.
