I know that 5 is a function because each x value has one solution
Answer:
5400
Step-by-step explanation:
so 90% of 850 is 765 (0.90x850)
765 is 10 years
so 1 year is 765/10 = 76.5 per year. So 76.5x59 = 4,513.5 add the initial ammount and you got 5,363.5 in the nearest hundredth you get 5400
Answer:
7
Step-by-step explanation:
The question asks for f(3). f(3) is the y value. "3" is the x value. In other words the question asks, "What is the value of y when x is 3?"
When x is 3, y=7.
Answer:
Option (2) is correct.
a = 3
Step-by-step explanation:
Given : equation 4a + 3(a + 1) = 24
We have to solve for a and choose the correct option from the given options.
Consider the given equation 4a + 3(a + 1) = 24
Multiply each term in bracket with 3, we have,
4a + 3a + 3 = 24
Adding 4a and 3a , we have,
7a + 3 = 24
Subtract 3 both sides, we have,
7a + 3 - 3 = 24 - 3
Simplify,
7a= 21
Divide both side by 7, we have,
a = 3
Thus, option (2) is correct.
