Step-by-step explanation:
Answer:
Step-by-step explanation:
you add the exponents
4 + (- 5) + (- 2) = 4 - 5 - 2 = -3
If you would like to know what is f(2), you can calculate this using the following steps:
f(0) = 2
f(n+1) = - 2 * f(n) + 3
f(1) = - 2 * f(0) + 3 = - 2 * 2 + 3 = - 4 + 3 = - 1
f(2) = - 2 * f(1) + 3 = - 2 * (-1) + 3 = 2 + 3 = 5
The correct result would be f(2) = <span>5.</span>
Sarah is older than 44.
Her age, a, minus 44 is a positive number.
a - 44 is positive
4 times the difference is 4(a - 44)
That equals 64, so we have
4(a - 44) = 64
Divide both sides by 4
a - 44 = 16
Add 44 to both sides
a = 60
Sarah's age is 60.
Check: Sarah is 60.
The difference between Sarah's age and 44 is 60 - 44 = 16
4 times that difference is 16 * 4 = 64.
Our solution is correct.
