AlladinOne [14]

Answer:

$y = \frac{x}{2}+15$ will be the equation that can be used to predict the number of minutes after 4:00 pm she will arrive at her destination.

Step-by-step explanation:

Let x represent the time, in minutes, of her original flight plan.

Let y represents the time, in minutes, of her new flight plan.

The time of Original flight schedule = 4:00 pm

The number of minutes delayed by Original flight = 15 minutes

As the new flight plan is two times faster than original flight plan.

So, the equation of new flight plan will be:

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

$y = \frac{x}{2}$

But, the original flight plan was delayed by 15 minutes. Hence, the equation to predict the number of minutes after 4:00 pm she will arrive at her destination will become:

$y = \frac{x}{2}+15$

So, $y = \frac{x}{2}+15$ will be the equation that can be used to predict the number of minutes after 4:00 pm she will arrive at her destination.

How can you use a graph to write an equation

olga55 [171]

In order to use a graph to write an equation, you first need to have plot points. Pick 2 points on the line if there isn't already any on the graph. After you find two points, find the slope. (Formula: y = mx + b) After you solve the slope, try finding the y-intercept. (Meaning: when x = 0, solve for y) The y-coordinate when you solve it is the value of "b" in the equation. (REMEMBER: y = mx + b) If you have any questions about the formula or the directions, remember to ask! Cheers, mimiisawesome5

5. If on a scale drawing 60 miles

HACTEHA [7]

Answer:

6 miles

Step-by-step explanation:

60 miles : 5 inches

12 miles : 1 inch

6 miles : 1/2 inch

whatever you do to one side of the ratio you have to do to the other.

to get from 1 to a 1/2 you divide by 2, so you do 12 divided by 2 which is 6.
