F the value of x decreases by 6, how does the value of m(x + 9) change?

Yuki888 [10]

start with y= m(x+9)

Use the distributive property:

y= mx+9m

Now you want x to decrease by 6:

so y ' = m(x-6) + 9m

Use distributive property again:

y'= mx - 6m + 9m

y' = (mx+9m) - 6m

y' = y - 6m

So the value of y decreases by 6m.

The mean temperature of the orange juice is 5 °F greater than the mean temperature of the water

<h3>Calculating Average</h3>

From the question, we are to calculate how much greater the mean temperature of the orange juice is than the mean temperature of the water

From the given chart,

Mean temperature of orange juice = $\frac{59+65+72+78+85+81}{6}$

Mean temperature of orange juice = $\frac{440}{6}$

Mean temperature of orange juice = 73.33 °F

Mean temperature of water = $\frac{55+62+68+71+79+75}{6}$

Mean temperature of water = $\frac{410}{6}$

Mean temperature of water = 68.33 °F

Difference in temperature = 73.33 °F - 68.33 °F

Difference in temperature = 5 °F

Hence, the mean temperature of the orange juice is 5 °F greater than the mean temperature of the water
