It is necessary when you are getting into multiplying from the outside of parenthesis and multiplying variables inside of parenthesis.
ex: 5(3 + 3x)
5 * 3 = 15
5 * 3x = 15x
so final set up would be 15 + 15x
The slope is 0.6
The answer is taken by solving from the graph
9514 1404 393
Answer:
Step-by-step explanation:
The form of the equation you are given is called "point-slope" form. The "slope" in this case is the per-hour fee. The point is (9 h, $195). Point-slope form generally looks like this:
y -k = m(x -h) . . . . . line with slope m through point (h, k)
Here, you have m=15, (h, k) = (9, 195), so the equation looks like ...
y -195 = 15(x -9)
__
The "one-time fee" is the cost when hours are zero.
y -195 = 15(0 -9)
y = 195 -9(15) = 60 . . . . add 195 to both sides, and evaluate
The one-time fee is $60.
use one five dollar box then use 4 4 $ boxes then its five dollar boxes the rest of the way so it would be 59 5$ boxes then Four 4$ boxes
The formula for the area of a square is the side squared, or multiplied together.
Basically, if the side length is x, the area is x*x or x^2.
We can use that to set up an equation.
x^2=121
x=square root of 121=11
Hope this helps!
