It is a disjunction. I hope it will work.
Answer:
D. $53
Step-by-step explanation:
Given the function, f(x) = 10x + 8, representing how much Jack earns working for x hours, if Jack works from 2:30 P.M to 7:00 PM, it means Jack worked for 4 hours 30 minutes, which is 4.5 hours (30 minutes = 0.5 hr).
Therefore, to find out how much he earned working for 4.5 hours, substitute x = 4.5 in 
✅Jack will earn $53 for working between 2:30 PM and 7:00 PM
Answer:
When x = 2.4, we have y = 10.8
Step-by-step explanation:
A direct variation of two variables, x, and y, can be written as:
y = k*x
Where k is a constant, called the constant of variation.
We know that y = 7.2, when x = 1.6
Then we can replace these two in the above equation to get:
7.2 = k*1.6
Now we can solve this for k:
7.2/1.6 = k = 4.5
Then our relation is:
y = 4.5*x
Now we want to find the value of y, when x = 2.4
Then we just need to replace x by 2.4 in the above equation:
y = 4.5*(2.4) = 10.8
y = 10.8
Answer:
77.35
Step-by-step explanation:
8x7=56
7x6.1=42.7
42.7x0.5=21.35
56+21.35=77.35
Polynomials are not closed under division. When you divide polynomials it is possible to get quotients with negative exponents or with fractions that have exponents in the denominator, and neither of these could be included in polynomials.
