The mean means average. To find it, add together all of your values and divide by the number of addends. The median is the middle number of your data set when in order from least to greatest. The mode is the number that occurred the most often. The range is the difference between the highest and lowest values.

What is the slope of 4x+5y= -10

Aleonysh [2.5K]

Answer:

$-\frac{4}{5}$

Step-by-step explanation:

To find the slope, rearrange the equation to y=mx+b or y=mx+c.

$4x+5y=-10$

Subtract 4x from both sides:

$5y=-10-4x$

Divide 5 on both sides:

$y=\frac{-10-4x}{5}$

$y=-\frac{4}{5} x-2$

In the equation of y=mx+b/y=mx+c, m will be the slope.

Therefore, the slope is $-\frac{4}{5}$

So after one month, FE (fitness explosion) costs $26 and Fitquest is $70; two months it's FE = $52, FQ = $85; three months it's FE = $78, FQ = $100; four months FE = $104, FQ = $115; five months FE = $130, FQ = $130. So answer C. 5 months is correct.
