Answer:
t + s >= 20 and t > = s + 5
Step-by-step explanation:
Let the number of working hours as a math tutor be t and the number of working hours at the grocery store be s.
It is told that Olivia works no fewer than 20 total hours at the two jobs.
So,
number of working hours as a math tutor + number of working hours at the grocery store >= 20
=> t + s >= 20 ____(1)
Again, it is told that she always spends at least 5 more hours working as a math tutor than she spends working at the grocery store.
So,
number of working hours as a math tutor >= number of working hours at the grocery store + 5
=> t > = s + 5 ____(2)
You would count on.
I hope i am right
Answer:
1.80
Step-by-step explanation:
it very useful to understand very well
1. (x² + 24) factors as the difference of two squares (x² - (-24)) where -24 is the square of the complex number i√24 = 2i√6. The factoring is
(x - 2i√6)(x + 2i√6)
2. The square of half the coefficient of the x-term needs to be added: 4.5² = 20.25
This number goes in both boxes.
3. This is the square of (y² +20), so the factorization is similar to that for problem 1.
y⁴ + 40y² + 400 = (y² + 20)² = (y -2i√5)²(y +2i√5)²
