You can find any ordered pair in which the y coordinate is 4 times the x coordinate.

For example, an ordered pair could be (2,8) or (5,20)

Daniel has $25 to spend at the fair. If the admission to the fair is $4 and the rides cost $1.50 each , what is thw greatest num
kondor19780726 [428]
$25 is the total amount of money.
Admission is a constant, meaning that price will not vary and is fixed.
The rides each cost something so the price of rides will vary, unlike the constant (admission). 

Thus making x the number of rides, we have the equation:
25 = 4 + 1.5x.
We need to solve for x, but x must be a whole number so we will round down if the solution is not an integer.

1.5x = 21
Divide by 1.5 on both sides.
x=14

Daniel can go on 14 rides maximum.

Which of the following best describes the slope of the line below?
LiRa [457]

Answer:

B. zero

Step-by-step explanation:

Lines with negative slopes slant downward from left to right

Lines with positive slopes slant upward from left to right.

Lines with undefined slopes are vertical lines.

Lines with zero slopes are horizontal lines.

This is a horizontal line, so it must have a slope of zero. This is because it is a horizontal line, and the y-coordinate never changes.

Find a formula for the inverse of the function. f(x) = e^6x − 9
STatiana [176]

Answer:

f^{-1}(x)=\frac{1}{6}\ln(x+9)

Step-by-step explanation:

So we have the function:

f(x)=e^{6x}-9

To solve for the inverse of a function, change f(x) and x, change the f(x) to f⁻¹(x), and solve for it. Therefore:

x=e^{6f^{-1}(x)}-9

Add 9 to both sides:

x+9=e^{6f^{-1}(x)}

Take the natural log of both sides:

\ln(x+9)=\ln(e^{6f^{-1}(x)})

The right side cancels:

\ln(x+9)=6f^{-1}(x)

Divide both sides by 6:

f^{-1}(x)=\frac{1}{6}\ln(x+9)

And we're done!
