Answer:4
Step-by-step explanation: add 3+1
Hi
we have 2x-4x-9=29
we add nine on both sides and get 2x-4x=38.
2x-4x=-2x, so we simplify the equation to -2x=38.
divide by -2 on both sides, x=-19
hope this helps

Step-by-step explanation:
The formula for calculating compound interest continuously is:
Where A is the amount of money obtained after t years.
r is the compound interest rate and p is the initial amount
In this case we have that:
Then we must find the final amount A
Answer:
x=9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(3x+8)=175
(5)(3x)+(5)(8)=175(Distribute)
15x+40=175
Step 2: Subtract 40 from both sides.
15x+40−40=175−40
15x=135
Step 3: Divide both sides by 15.
15x/15=135/15
x=9
Answer:
The values of x that satisfy the given equation are:
x1 = 1.183 + nπ
x2 = -1.183 + nπ
Step-by-step explanation:
Given tan²x - sin²x/sin²x = 5
Simplifying this, we have
tan²x - 1 = 5
Adding 1 to both sides, we have
tan²x = 6
Because tan²x = (tanx)², we can write as
(tanx)² = 6
Taking square roots of both sides, we have.
tanx = ±√6
x = arctan(±√6) + nπ
≈ 1.183 + nπ or -1.183 + nπ
