Answer:
f(x) = 6 x^2 - 1
f(2) = 6 * 2^2 - 1 = 23
f(-1) = 6 * -1^2 - 1 = 6 * 1 - 1 = 5
f(2) - f(-1) = 23 - 5 = 18
Answer:
400
Step-by-step explanation:
There are 599 numbers from 1 to 599.
There are
INT(599/4) = 149 numbers divisible by 4 and
INT(599/6) = 99 numbers divisible by 6,
However, some of these numbers have been counted twice. For example, 12 is counted twice, because 12 is divisible by both 4 and 6. There are
INT(599/12) = 49 numbers divisible by 12.
599 numbers
-149 divisible by 4
- 99 divisible by 6
<u>+49 double-counts
</u>
400 numbers not divisible by 4 or 6.

Step-by-step explanation:
x = devaughn age
y = sydney age
x = y - 9
x + y = 61
y-9 + y = 61
2y= 61+9
2y = 70
y = 35
x = 35 - 9 = 26
check
35 + 26 = 61
35- 26 = 9
Hope this helps!
