Answer:
No, ten is equal to ten. If you see a less than/equal to sign, the statement is true.A less than/equal to sign has a less than sign on top of an equal sign.
Step-by-step explanation:
The vertex is a maximum for f(x) and a minimum for g(x). This is because the squared term is never negative.
Because the larger the squared term is, the smaller f(x) is, f(x) is at MOST 5. Similarly, because the larger the squared term is, the larger g(x) is, g(x) is at MOST -3.
Answer:
EZ 3.1, 3.2 3.5, 4.2
Step-by-step explanation:
I don't know how you explain that but I just converted the 3 and 1/5 into 3.5 and put them in order.
Answer:
Step-by-step explanation:
There might be a shorter way of doing this and a better one as well, but here is how I did it.
Let the three numbers be
Solution
Note that these three numbers are consecutive and even.
Twice the smallest number is 2 * (2n - 2)
20 more than the second number is 2n + 20
Now equate them.
2(2n - 2) = 2n + 20 Remove the brackets.
4n - 4 = 2n + 20 Add 4 to both sides
4n - 4 + 4 = 2n + 20 + 4
4n = 2n + 24 Subtract 2n from both sides.
4n - 2n = 2n - 2n + 24
2n = 24
Now stop
Answers
- The middle number is 24
- The smallest number is 24 - 2 = 22
- The largest number is 24 + 2 = 26
Check
22*2 = 44
The middle number = 24 + 20 = 44
