On #9, you subtract 158 from 180 because its a 180degree angle. so once you solve 180-158 which is 22. you then add 22 to 58 and then subtract your answer from 180 because all of the angles of a triangle should add up to 180. The answer to #9 is 100

The exterior angle is equal to the 2 remote interior angles. For example, #7 is 80 degrees because the two remote angles(54 and 26) added together equal 80 degrees. Also, #9 would be 100 because the exterior angle is given to you. Since the 2 remote angles equal the exterior, all you do is 158+58=100

What is y in the equation 7/5y=3-1/5

enot [183]

Answer:2

Step-by-step explanation:first you subtract 3 and 1/5 and you'll get 2 4/5 then make that an improper fraction which will be 14/5 and then flip your 7/5 and multiply both sides by it so your 7/5 will be multiplied by 5/7 and they will cancel out the you take 14/5 and multiply it by 5/7 and you'll get y=2

What are the possible numbers of positive, negative, and complex zeros of f(x) = −x6 − x5 − x4 − 4x3 − 12x2 + 12?

ad-work [718]

$f(x) = -x^6 -x^5 - x^4 - 4x^3 - 12x^2 + 12$

There is only one change of sign, so there is only one possible positive root.

$f(-x) = -(-x)^6 -(-x)^5 - (-x)^4 - 4(-x)^3 - 12(-x)^2 + 12\\
f(-x) = -x^6 +x^5 - x^4 + 4x^3 - 12x^2 + 12$

There are five changes of signs, so there are 5,3 or 1 possible negative roots.

The number of complex roots can be equal to 4,2 or 0 (degree of a polynomial - possible positive roots - possible negative roots)
