Answer:
x = 37 y = 12
Step-by-step explanation:
Let x be one number
Let y = other number
x+y = 49
x-y = 25
Add the equations together
x+y = 49
x-y = 25
---------------
2x = 74
Divide by 2
2x/2 = 74/2
x =37
x+y = 49
37+y = 49
Subtract 37 from each side
37+y-37 = 49-37
y = 12
0.03 you just times it by ten or if its a decimal take away the 0 infront of it

Answer:
-5x-12
Step-by-step explanation:
Given f(x) = -5x+3, to get f(x+3), we are going to replace x in f(x) with x+3 as shown;
f(x) = -5x+3
f(x+3) = -5(x+3)+3
f(x+3) = -5x-15+3
f(x+3) = -5x-12
Hence the function f(x+3) is -5x-12
