Inverse functions will be given by the following equation:
k is a constant value that the two variables must multiply to.
Plug in your t and r values:
k = 385.
Now we'll have to find a value that multiplies with 65 to equal 365.
Set up the following equation:
This equation can also be treated as the following:
Divide both sides by 385 to get x by itself:
The answer is
C. about 5.92 hrs to drive the same distance of 385 miles.
Answer:
y=0.25x+35
Step-by-step explanation:
if the truck doesn't have to travel at all, it costs $35 for the loading fee, so the y-intercept is (0, 35). As x increases by 1, y increases by 0.25, so the slope is 0.25. Therefore, the equation is y=0.25x+35
Answer:
25%
Step-by-step explanation:
125.00x = 93.75
x = 93.75 / 125 = 0.75
meaning that 93.75 is 75% of 125
and, therefore, the item was discounted 100 - 75 % = 25%
Points Lying on the undefined curve are
x : 0 1 2 3 4
f(x): 3 7 29 87 199
Plotting the points on the coordinate plane
As you will see, the value of x increases , value of y increases .
It is not linear, because slope between two points is not same.
Neither quadratic nor cubic , it is not cutting x axis .
So, As value of x increases, value of y does not increases by a fixed quantity, but it increases.
So, option (D) Exponential ,Function word is the right word Describing these points.
Answer:
y = - 2(x - 1)² + 18
Step-by-step explanation:
- 2x² + 4x + 16 ← factor out - 2 from the first 2 terms
= - 2(x² - 2x) + 16
using the method of completing the square
add/subtract ( half the coefficient of the x- term)² to x² - 2x
= - 2(x² + 2(- 1)x + 1 - 1) + 16
= - 2(x - 1)² + 2 + 16
= - 2(x - 1)² + 18 ← in vertex form
