Answer: 80

Step-by-step explanation:

Your original equation is 10(n - 6)

You know what the value of n is: 14

Now go into your equation since the value of n is 14, replace n with 14 giving you the expression

10(14 - 6)

Now do the subtraction inside the parentheses

10(8) = 80

That should be your answer I hope this helps you :)

Answer:

1/3 (one-third)

Step-by-step explanation:

A scale factor that produces an image smaller than the original figure is less than 1. A scale factor that produces an image bigger than the original figure is more than 1.

Thus, the only option that's less than 1 is one-third.

Y-3x=13 for y can someone please help me

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$y - 3x = 13$

Add sides 3x

$y - 3x + 3x = 13 + 3x$

$y = 13 + 3x$

$y = 3x + 13$

Given:

The distance (in kilometers) Dora hiked is modeled as a function of time.

We need to determine the average rate of change in distance hiked, measured in kilometers per hour, between 8:30 am to 1:30 pm.

Average rate of change:

Let us write the time and the distance hiked in coordinates for the time 8:30 am and 1:30 pm.

Thus, the coordinates are (8.30, 4) and (1,12)

The average rate of change can be determined using the formula,

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

Substituting the points (8.30, 4) and (1.30,12), we get;

$m=\frac{12-4}{1.30-8.30}$

$m=\frac{8}{-7}$

$m=-1.14$

Rounding off to the nearest whole number, we get;

$m=-1$

Therefore, the average rate of change is -1.
