Since line c and d are parallel, line a can act as a transversal. Thus, x=124 degrees because of the alternate exterior angle relationship that can be seen.
Answer:
if the stone makes 150 revolution per minute, the tension force of the string on the stone is
Start by decomposing the number inside the root into primes
Then group the terms into cubes if possible

rewrite the root
![\sqrt[3]{80}=\sqrt[3]{10\cdot2^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B80%7D%3D%5Csqrt%5B3%5D%7B10%5Ccdot2%5E3%7D)
then cancel the terms that are cubes and bring them out of the root
Answer:
x ≤ 2
Step-by-step explanation:
Isolate the variable, x. Note the ≤ sign, treat it like an equal sign, what you do to one side, you do to the other.
First, subtract 3 and x from both sides:
2x (-x) + 3 (-3) ≤ x (-x) + 5 (-3)
2x - x ≤ 5 - 3
Simplify:
2x - x ≤ 5 - 3
x ≤ 2
x ≤ 2 is your answer.

Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
Find the domain of g(y), and this will be the range of f(x). ...
If you can't seem to solve for x, then try graphing the function to find the range.
