Answer:
pit it on -4 because your reflecting it on x
Answer:
2 or -2
Step-by-step explanation:
If x² - 8x = -12
Step 1
We find x by solving
x² - 8x = -12
We equate to zero
x² - 8x + 12 = 0
We factorise
x² - 6x - 2x + 12 = 0
x(x - 6) -2(x - 6) = 0
(x - 6) (x - 2) = 0
x - 6 = 0, x = 6
x - 2 = 0, x = 2
x = 6 or 2
Step 2
What is x - 4?
When x = 6
= 6 - 4 = 2
When x = 2
= 2 - 4 = -2
Therefore, x - 4 = 2 or -2
Answer:
Step-by-step explanation:
34t = 14
Dividing through by 34
t = 14/34
t = 7/17
Substitute sin(x) = tan(t) and cos(x) dx = sec²(t) dt. We want this change of variable to be reversible, so let's assume bot x and t are bounded between 0 and π/2.
Then we have
Recall the Pythagorean identity,
1 + tan²(t) = sec²(t)
Then
√(1 + tan²(t)) = √(sec²(t)) = sec(t)
and the integral reduces to
Change the variable back to x, so the antiderivative is
The maximum proper temperature for hot chocolate is 175°F
The minimum proper temperature for hot chocolate is 145°F
Linear equation are the equation that contains one or more variables whose maximum degree is 1 and is equated to zero
Linear equation of one variable can be solved directly equating to zero.Whereas, equations ith higher no. of variables have various method s to solve.
x=160±15°F
x(min)=145°F
x(max)=175°F
Therefore, the maximum and minimum proper temperature for hot chocolate is 175°F and 145°F
