(4,3) is a solution for y=3x-9 but not y=1/2+1.
Answer:
67.9705...
Add the two numbers.
67 16/34 + 14/28 = 67.9605...
That is your answer.
Z= (X-mean)/s.d.
X (height in inches) = (Z*sd)+mean = (1.5*2.4)+54 = 57.6 in
3.5x-10>-3 add 10 to both sides
3.5x>7 divide both sides by 3.5
x>2
... now for the other inequality:
8x-9<39 add 9 to both sides
8x<48 divide both sides by 3
x<6
So we have x>2 and x<6, so the compound inequality is:
2<x<6 and this means that the solution set is:
x=(2, 6)
