50-26=24 she used 24 so far

24/12=2 each ride was 2

Hi!

We will solve this by creating a equation, like this:

26 + 12*x = 50 , where x is price of each ride

12*x = 50 - 26

12*x = 24

x = 24/12

x = 2

The price of each ride is 2.

Hope this helps!

The output of a function is 5 more than 2 times the input. Find the input when the output is 17.

Tanya [424]

Answer:

The input when the output is 17 is x=6.

Step-by-step explanation:

Functions

Assume the input is called x and the output is the function f(x). Two times the input is 2x. 5 more than that is 2x+5.

Knowing the output of the function is 5 more than 2 times the input, we can write the function as:

f(x)=2x+5

Now find the input x when the output is 17:

17=2x+5

Swap sides of the equation:

2x+5=17

Subtract 5:

2x=17-5=12

Divide by 2:

x=12/6=6

The input when the output is 17 is x=6.

Graph the line that passes through the points (-4,-6) and (-2,-7) and

Komok [63]

Answer:

$y=-\frac{1}{2}x-8$

Step-by-step explanation:

$(-4,-6)(-2,-7)$

Step 1. Find the slope (by using the slope-formula)

m = slope

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{-7--6}{-2--4}$

$m=\frac{-1}{2}$

$m=-\frac{1}{2}$

Step 2. Create the equation of a line that has a slope of $-\frac{1}{2}$

$y=-\frac{1}{2} x+b$

Step 3. Find the y-intercept

To do this, use any of the two points and substitute their x and y values

$y=-\frac{1}{2}x+b$

point: $(-2,-7)$

$(-7)=-\frac{1}{2}(-2)+b$

$(-7)=1+b$

$b=-7-1$

$b=-8$

Step 4. Write the equation in Slope-intercept form

$y=mx+b$

$y=-\frac{1}{2} x-8$

Solving for y. - y = -2x -5

Effectus [21]

Answer:

y = 2x+5

Step-by-step explanation:

Add y on both sides, this cancels out the y on the left side

add 2x and add 5 on both sides, this cancels out the -2x and the -5 on the left side.

OR

Divide/Multiply both sides by -1, as it will cancel out the negatives as two negatives make a positive.

If you needed a value for y, more info is needed.

hope this helps (:
