Compare the two functions to see which has a greater rate of change. Function 1
AleksAgata [21]

Function 2 has greater rate of change

Step-by-step explanation:

In order to find the rate of change we have to covert the given linear functions in slope-intercept form

<u>Function 1:</u>

<u></u>-2x+5y = 10<u></u>

Adding 2x on both sides

<u></u>-2x+5y+2x = 2x+10\\5y = 2x+10<u></u>

Dividing both sides by 5

<u></u>\frac{5y}{5} = \frac{2x+10}{5}\\y = \frac{2}{5}x +\frac{10}{5}\\y = \frac{2}{5}x+2<u></u>

Let m1 be rate of change of function 1:

<u></u>m_1 = \frac{2}{5}<u></u>

<u></u>

<u>Function 2:</u>

<u></u>-6x+3y = 18<u></u>

Adding 6x on both sides

<u></u>-6x+3y+6x = 6x+18\\3y = 6x+18<u></u>

Dividing both sides by 3

<u></u>\frac{3y}{3} = \frac{6x+18}{3}\\y = \frac{6x}{3} + \frac{18}{3}\\y= 2x+6<u></u>

Let m2 be the slope of function 2

<u></u>m_2 = 2<u></u>

As we can see that

<u></u>m_2>m_1<u></u>

Function 2 has greater rate of change

How do the values compare? Order the values from least to greatest.
aleksley [76]
Im pretty sure it would be ordered: -2 1/2, -1/2, |1/2|, 1 1/2, |-2|, |-2 1/2|

This is because
-1/2 stays as -1/2
the absolute value of |-2| is 2
the absolute value of |1/2| is 1/2
the absolute value of |-2 1/2| is 2 1/2
-2 1/2 stays as -2 1/2
and 1 1/2 stays the same as well.
If you take all these numbers (-1/2, 2, 1/2, 2 1/2, -2 1/2, and 1 1/2) and order them from least to greatest, you would get:
-2 1/2, -1/2, 1/2, 1 1/2, 2, 2 1/2
which is -2 1/2, -1/2, |1/2|, 1 1/2, |-2|, |-2 1/2|

Im not exactly sure if it is all correct, but i hope this helps! :)

3) Tara sold candles to raise money for new playground equipment at her school.
Ronch [10]

Answer:

Tara's current expression finds how much the school will be keeping. 50 x 2/5 (also written as 50 x 0.4) totals out as 20. $20 is 2/5 of $50. The expression that Tara SHOULD have written to find how much goes to the candle company would be 50 x 3/5 (also written as 50 x 0.6), as this adds up to 30. $30 is 3/5 of $50.

Step-by-step explanation:

50/5 = 10 which means that 1/5 of 50 = 10.

2/5 of 50 ($20) is kept by the school. This is what Tara's expression finds. This means that $30 is sent to the candle company, and can be found with the expression 50 x 3/5.

The decimals are created by dividing the numerator of the fraction by the denominator (I find it easier to do math with decimals).
