Answer:
x = 26.45
Step-by-step explanation:
Cos theta = adjacent side / hypotenuse
cos 50 = 17 /x
Switch the x and the cos 50
x = 17 / cos 50
x =26.44730506
Rounding to 2 decimal places
x = 26.45
Answer:
Yes.
From Definition - A special relationship where each input has a single output.
Check if there is going to be one y for one x.
Step-by-step explanation:
- Re-write it in terms of y=…., meaning solve for y
- If it looks like you have two equations then it is a relationship -case a
- If you need to prove that one has a function for case b, you would point out that if you substitute any value you will get some value in Reals.
To evaluate this expression you just have to substitue the value that is given.
so since we know m=2 x=7 y=5
and the expression is given mx-y
plug these values in as 2(7)-5 = 14-5 = 9
