Although the question is incomplete, I have seen it before.

The equations are:
3a + 6b = 12
-3a + 6b = -12

Adding the equations, we get:

12b = 0
And b = 0

galina1969 [7]

Answer:

The rate of change or slope m  = -50

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

  • m is the rate of change or slope
  • b is the y-intercept

Given that there is $500 in Holly's bank account.

Thus, the y-intercept b = 500

It is stated that she takes out $50 from her account each month but doesn't put money back in.

It means the rate of change or slope is decreasing.

Thus, the rate of change or slope m  = -50

<u>EXTRA BONUS!</u>

We can also determine the line equation by substituting m = -50 and b = 500 in the slope-intercept form

y = mx+b

y = -50x + 500

Here:

The slope m = -50

The y-intercept = 500

vodomira [7]

Answer:

Isabel's bee rounds to 0.8 inches and Pablo's bee round to 0.5 inches..

Step-by-step explanation:

Look at the attached picture.

The students in Mr. Bhatia's  class measure the length of four bees.

If we round the lengths to the nearest tenth we get:

Isabel’s bee rounds to 0.8 inches

Pablo’s bee rounds to 0.5 inches

Wendi’s bee rounds to 0.6 inches

Brett’s bee rounds to 0.7 inches

This shows that Isabel's bee rounds to 0.8 inches and Pablo's bee round to 0.5 inches..
