Simplify and evaluate without a calculator. 3*(m-4)-n*(m-4) if m=5 and n=3

Answer:
Step-by-step explanation:
If m = 5 and n = 3, then
3*(m-4)-n*(m-4) becomes 3*(5 - 4) - 3(5 - 4), or 3(1) - 3(1) = 0
Another way to do this would be to factor out m - 4 first. We get:
(m - 4)(3 - n), and substituting the given values for m and n results in
5(3 - 3) = 0 (as before).
Answer:
0
Step-by-step explanation:
3*(m-4)-n*(m-4) m = 5, n = 3
3*(5-4)-3*(5-4)
3*(1)-3*(1)
3-3

Answer: the graph of the resulting function, |x| + k, is the graph of f (x) shifted k units up
Step-by-step explanation:
just took the test
Because f(x)=x, goes through origin. So x and y -intercept are one point (0,0).
Answer:
y=-2x + 3
Step-by-step explanation:
It’s only a vertical angle
