Y= -2x-5
Y=8x+5
^^ those two equations are basically the same so you put them side by side like:
-2x-5=8x+5
Subtract 5 on both sides which leads to:
-2x-10=8x
Add 2x both sides:
-10=10x
Divide both sides by 10
-1=x
The conversion factor between radians and revolution as measures of angle is 2π rad is equal to 1 revolution. Converting the given angular velocity to rev/s,
(2.8 rad) x (1 rev / 6.28 rad) = 70/157 revolution per second
Dividing the given angle, 20 rev by the velocity,
(20 rev) / (70/157 rev/s) = 44 6/7 s
Thus, the answer is approximately 44.9 seconds.

Here are a few rules with exponents that apply here:
- Raising a power to a power:
- Dividing exponents of the same base:
- Converting negative exponents to positive ones:
Firstly, solve the outer exponent:
Next, divide:
Next, convert the negative exponents:
