Answer:
x=9, x=7
Aka x= 9,7
Step-by-step explanation:
Oh goodie, factoring.
I used to be very good at this. My memory is a LITTLE rusty but let's see if we can bust out some penzoil and fix my aching joints (yes I just stole the quote from that terrible show, sue me), shall we?
1. x^2 - 11x + 68 = 5x +5
2. Chuck all the x variables to the left: x^2 - 16x + 68 = 5
3. Get rid of that pesky loser, 5, by subtracting from both sides of the equation (Note that it's important to remember LIKE TERMS, don't try subtracting 5 from 16x, you'll hurt yourself): x^2 - 16x + 68 - 5 = 5 - 5
New equation: x^2 - 16x + 63 = zilch (0)
4. Use AC method to factor: x2+bx+c. AC method definition: a pair of numbers whose product is c and whose sum is b: (x-9)(x-7)=0
5. Solve for x.
Booyah.
Answer:
Below in bold.
Step-by-step explanation:
x-intercepts (-3,0) and (6, 0)
y-intercept (0, -5)
Axis of symmetry:
(-3 + 6) / 2 = 1.5
x = 1.5.
Domain = all real x.
Range is f(x) ≥ -6.
Graph is positive for x < -3 and x > 6.
Negative for -3 < x < 6.
Increasing for x > 1.5 and decreasing for x < 1.5.
We know, tan x = 1 / cot x
So,tan x = 1/ 0.78
tan x = 1.28
In short,Your Answer would be 1.28
Hope this helps!
