Answer:

3 full miles; anything less than 4 miles

Step-by-step explanation:

5 + 2.50x = 15

subtract 5 from both sides

2.50x = 10

divide both sides by 2.50

x = 4

4 miles is how long he can travel by spending all $15

Anything less will cost him less than $15

In the equation y=mx+b, what does the x stand for? And, in the equation y=3x+6 how would I solve for y?

ladessa [460]

Answer:

x stays x in both equations so x stands for x

Step-by-step explanation:

y=3x+6

you can put this into a graphing caculator or draw it yourself.

6 is the y value when x equals 0. and the 3 represents the slope so then it is solved for any y value

The average rate of change of a function f(x) = x2 between x = 3 and x = 9 is

masya89 [10]

Answer:

12.

Step-by-step explanation:

Average rate of change = (value of the function when x = 9 - value when x=3)

(9 - 3)

= f(9) - f(3) / (9-3)

= (9^2 - 3^2) / (9-3)

= 72 / 6

= 12.

Answer:

$-\dfrac{3}{5}$

Step-by-step explanation:

1. Find the numerator:

$\dfrac{1}{3}-\dfrac{5}{6}=\dfrac{1\cdot 2}{3\cdot 2}-\dfrac{5}{6}=\dfrac{2}{6}-\dfrac{5}{6}=\dfrac{2-5}{6}=-\dfrac{3}{6}=-\dfrac{1}{2}.$

2. Simplify the fraction:

$\dfrac{-\frac{1}{2}}{\frac{5}{6}}=-\dfrac{1}{2}\cdot \dfrac{6}{5}=-\dfrac{3}{5}.$

$\mathbb\pink{NOTE:}$

The difference between the y-coordinates of the two points is called the rise.
The difference between the x-coordinates of the same two points is called the run.
The slope can be calculated by dividing the rise by run.
