First divide both sides by 2:
Move the constant term to the right side:
Since
we want to have
Then
So in our equation, we need to add 49/16 to both sides in order to complete the square:
It is not an equation, it's a function & I guess you have to draw it
h(x) = - 2x/3 - 11/3
It's a linear function: To draw it, try to find 2 points, say A & B.
To find A, plug any (logical) number into x to find y. For instance , let x=0, if so y=-11/3 & the coordinate of the first point A(0, - 11/). Try to find B by following the same methodology
Answer:
The Spiral of Theodorus is a construction of continuous right triangles, and each triangle has a side length of one representing the of the Pythagorean theorem, with the other sides filling in the spaces for the and in the theorem. hope that helped :)
Step-by-step explanation:
Input is time, this is your x-values
output is the total cost, this is your y-values.
in the question above "this mapping diagram shows...." so i'm not sure if there more to the question or what the question actually is, but if you have to create a mapping, you will create a list of x values for days and y values for corresponding total cost.
Day 1 cost $40 (1,40)
Day 2 cost $80 (2, 80) ($40 per day for 2 days = 40 (2) = $80
Day 3 cost $120 (3, 120) ($40 per day for 3 days = 40(3) = $120
hope this answers your question. :-)
