Answer: $4 senior, $7 child
Step-by-step explanation:
(3s + 9c = 75)
8s + 5c = 67
Answer:
x ≤ 1
Step-by-step explanation:
First, add 5 to both sides (we want to isolate x).
3x ≤ 3
Now, we divide by 3.
x ≤ 1
That's the answer! All values equal to or less than 1 are solutions of 3x - 5 ≤ -2.
Hope this helps
Answer:
yes
Step-by-step explanation:
y(x) is even or odd according as y(−x)=±y(x) . Here, #y(-x)=-(-x)^3=-(-x^3)=x^3=-y(x). So, y is an odd function of x.
