Step 1: Add -f to both sides.
Step 2: Add -9g to both sides.
Step 3: Divide both sides by 5.
Answer
-6/5g
Answer:
<em>π/2 and π/3</em>
Step-by-step explanation:
Given the equation 2cos²x - cosx = 0, to find the solution to the equation, we will follow the following step.
let P = cosx
The equation becomes 2P²-P = 0
P(2P-1) = 0
P = 0 and 2P-1 = 0
P= 0 and P = 1/2
Since P = cosx
cosx = 0 and cos(x) = 1/2
If cos(x) = 0
x = cos⁻¹0
x = 90⁰
x = π/2
If cos(x) = 1/2
x = cos⁻¹1/2
x = 60⁰
x = π/3
<em>Hence the solutions to the equation are π/2 and π/3.</em>
The two horizontal lines are parallel.
This makes the 80 degree angle and the angle ox x and 20 degrees are alternate interior angles and are the same.
This means x + 20 needs to equal 80.
X = 80-20 = 60 degrees.
Answer:
-3
Step-by-step explanation:
The slope formula is y2-y1/x2-x1, so replace the variables with the given values.
-5-5/1-x= -5/2, now multiply both sides by "1-x"
-5-5= -5/2(1-x) or -10=-5/2+5/2x, now add 5/2 to both sides
-20/2+5/2=5/2x, now simplify the equation
-15/2=5/2x, multiply both sides by 2/5
-30/10=x or x is -3
