Answer:
x^2+17x+91=0
a = 1; b = 17; c = +91;
Δ = b2-4ac
Δ = 172-4·1·91
Δ = -75
Delta is less than zero, so there is no solution for the equation

Answer:
C
Step-by-step explanation:
To solve this problem, we need to first find the ratio of numbers less than four to total numbers.
There are 3 numbers on the wheel less than 4 (1, 2, and 3). There are 8 total numbers, meaning the ratio of numbers less than 4 to total numbers is 3:8.
Now, we need to find the probability of spinning a white number. There are 3 white numbers on the wheel (3, 5, 8). However, one of these numbers (3) is less than 4, so it is already accounted for in the previous ratio. There are 2 numbers left, meaning the ratio of remaining white numbers to total numbers is 2:8.
Adding this to the original equation, we get 5:8. As a fraction, 5:8 = 5/8. The answer that correctly highlights this is C.
X-6=0
Add +6 to both sides of the equation to get rid of -6 and leave x by its self.
X+1=0
Subtract -1 to both sides of the equation to get rid of +1 and leave x by its self.
Solution:
X= 6
X= -1
