Answer:
21 & 11
Step-by-step explanation:
Let x = first number and y = second number. We need to find the values of x and y, so we need to set up a system of linear equations. The first equation would be x + y = 32 because x and y add up to 32. Then the second equation would be x - y = 10 to represent that the two numbers have a difference of 10. Solving by elimination, we add and get 2x = 42, so x = 21. Then substitute 21 for x in either one of the equations to get y = 11.
Answer:
#4 y=-0.5(x-4)^2+1

Answer:
f(x) = 3
Step-by-step explanation:
Replace sin(x) with 0 and you will have it.
f(x) = 12·0 +3
f(x) = 3
