Answer:
Step-by-step explanation:
Given that there is a function of x,
Let us find first and second derivative for f(x)
When f'(x) =0 we have tanx = 1 and hence
a) f'(x) >0 for I and III quadrant
Hence increasing in 
and decreasing in 
Hence f has a maxima at x = pi/4 and minima at x = 3pi/4
b) Maximum value = 
Minimum value = 
c)
f"(x) =0 gives tanx =-1
are points of inflection.
concave up in (3pi/4,7pi/4)
and concave down in (0,3pi/4)U(7pi/4,2pi)
First, you need to add 4 to both sides so you’re left with 5/6x = 6
then, divide 6 by 5/6 to find x
for me personally, it help to write 6 as 6/1
cross multiply so both fractions have the same denominator
6 divided by 5/6 is 36/5 as a mixed number or 7 1/5

Answer:
The value of x is -5/3.
The value of 1/3 - x is 2.
Step-by-step explanation:
-3( x+2)-5=x-(6+x) Distribute
-3x + -6 - 5 = x - 6 - x Combine llike terms
-3x + -11 = -6 <em><u>POSITIVE AND NEGATIVE IS NEGATIVE</u></em>
-3x -11 = -6 Add 11 on both sides
-3x = 5 Isolate the variable by dividing -3 on both sides
x = -5/3
1/3 - x
= 1/3 - -5/3 <u><em> </em></u><u><em>NEGATIVE AND NEGATIVE IS POSITIVE</em></u>
= 1/3 + 5/3
= 6/3
<em>= 2</em>
<em>You must isolate the variable in order to solve equations with variables.
</em>

</em>
<em>Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on </em><u><em>ONLY </em></u><em>one side of the equation.

The answer is 8.7142, or as a mixed number, 8 and 3571/5000. I would really appreciate it if I could get brainliest! Thanks! =D
Answer:
[See Below]
Step-by-step explanation:
✦ First you're going to need to put it in a fraction form to solve this:
✧ ⁷⁄₁₄ = ˣ⁄₁₅
✦ Now multiply across:
✧ 7 * 15 = 105
✧ x * 14 = 14x
✦ Now divide:
✧ ¹⁴ˣ⁄₁₄ = x
✧ ¹⁰⁵⁄₁₄ = 7.5
✦ So x would be 7.5
