Roots of the equation are
Step-by-step explanation:
We need to find the roots of
Let the equation equal to zero
We can find roots by factorization
Solving:
For finding factors break the middle term such that their product equals to the product of first and last term and their sum equals to middle term
So, 8x can be break into -5x and -3x
Sum=-5x+(-3x)= -8x (same as middle term)
Product = -5x * -3x = 15x^2 (same as product of first and last term)
Taking common:
So, roots of the equation are

Step-by-step explanation:
-8x > 72
8x < -72
x < -72 ÷ 8
x < -9
Answer:
increase
Step-by-step explanation:
First, we need to find the mean of the given data set without any change.
10 + 61 + 10 + 44 + 21 + 79 + 27 + 12 = 264
264 ÷ 8 = <u>33</u>
Now that we have the mean, we can find the mean of the data set with the change of 52.
10 + 61 + 10 + 44 + 21 + 79 + 27 + 52 = 304
304 ÷ 8 = <u>38</u>
<u />
From this, we can see that the mean has increased with the change of 12 to 52. Thus, that's the correct option.
hope this helps!
