Answer:
r = 1/2(s -t/x)
Step-by-step explanation:
Here, we simply want to make r the subject of the formula;
We proceed as follows;
s = 2r + t/x
s - t/x = 2r
Divide both sides by 2
r = 1/2(s - t/x)
Answer:
no solutions
Step-by-step explanation:
4 + 5m = 4m + 1 + m <em>combine like terms</em>
4 + 5m = 5m + 1 <em>subtract 5m from each side</em>
4 = 1
4 can never equal 1, so no value of m would allow the equation to be correct
Answer:
-3x + 19
Step-by-step explanation:
f(x) = -5² - 4
f(x) = 25 - 4
f(x) = 21
(f+g)(x) = f(x) + g(x)
21 + -3x - 2
-3x + 19
