Answer:
the mean is 9
Step-by-step explanation:
add all the numbers then divide by 6
Y = 4/5x + 30
4/5 because the slope is 4 up, 5 right. 30 is the y-int
The correct option is: 53.9°
<em><u>Explanation</u></em>
According to the below diagram,
is acute triangle, in which
and 
If we <u>apply cosine rule</u> here, then we will get.....

Now, plugging the given values, we will get....

So, the measure of
is 53.9°
Answer:
D. y + 7 = -3(x - 5)
Step-by-step explanation:
Point-slope form: y - y₁ = m(x - x₁)
⇒ y - (-7) = -3(x - 5)
⇒ y + 7 = -3(x - 5)
