Answer:
v = 9/2 + sqrt(61)/2 or v = 9/2 - sqrt(61)/2
Step-by-step explanation:
Solve for v over the real numbers:
-v^2 + 9 v - 5 = 0
Multiply both sides by -1:
v^2 - 9 v + 5 = 0
Subtract 5 from both sides:
v^2 - 9 v = -5
Add 81/4 to both sides:
v^2 - 9 v + 81/4 = 61/4
Write the left hand side as a square:
(v - 9/2)^2 = 61/4
Take the square root of both sides:
v - 9/2 = sqrt(61)/2 or v - 9/2 = -sqrt(61)/2
Add 9/2 to both sides:
v = 9/2 + sqrt(61)/2 or v - 9/2 = -sqrt(61)/2
Add 9/2 to both sides:
Answer: v = 9/2 + sqrt(61)/2 or v = 9/2 - sqrt(61)/2

Step-by-step explanation:
Answer:
- False
- True
- false
Step-by-step explanation:
- The variable that changes is the price
- 30 is the slope and 6 is the y-int
- 30(.75) + 6 = 28.5
Answer:
C; 17.156
Step-by-step explanation:
a rational number is a number you could put in a ratio or fraction
We need to make sure c is on one side:
a + b - c = 180
So let’s subtract a and b from both sides:
-c = -a -b + 180
Now, multiply both sides by -1:
c = a + b - 180
Hope this helps!
