The 2nd Answer represents a function because it goes through the X and Y Axis
4t ^ 2 - 16 ÷8 ÷ t - 2 ÷6
=(4t ^ 2)-(16 ÷8 ÷ t)-(2 ÷6)
=(4t ^ 2)-(2/t)-1/3
=4t ^ 2-2/t-1/3
Answer:
x = -4
Step-by-step explanation:
An undefined slope would look like a vertical line, up and down. This is shown using an x equals equation instead of a y equals equation.
Since the line goes vertically, you only need to look at the x-value to make the equation, since after doing x = -4 the line would keep going down until it touched (-4, -8).
The line would touch everything in the y-value but stay at x = -4.
Therefore the answer to this problem is x = -4. I've attached a picture (from desmos) showing what the graph of x = -4 would look like and how it touches the point (-4, -8).
Elevation of Mount Fuji is: 3776 m
Elevation of Hachirogata: -4m
Difference between them is:
3776m -(-4m)
3780m.
Let f(x) represents function that tells us Derek's earning depending on square feet of lawn mowed which is x.
First we construct function:
f(x) = x/1000 * 1 + 30
x/1000 is a number that tells us the number of mowed units. for x = 1000 square feet he earns 1 dollar that is why we have to divide x by 1000.
if he earned 204 first week that means that x =:
204 = x/1000 + 30
x/1000 = 174
x = 174 000
if we check for each week that he worked we will see that square footage of the lawns he mowed match forth (last) option.
Answer is D.
