Let u = < 7, -3> , v = < -9, 5> . find 4u - 3v. < 55, -27> < 1, 3> < 16, 12> < -8, -6> i have no idea where to get started, so if you can explain how to solve this i would appreciate it!

(0,4)

Step-by-step explanation:

The y intercept is the y value when x = 0. All you have to do is run up the y axis until you see where the blue line intersects the y axis. In this case it is 4.

The y intercept is (0,4)

b. False

Step-by-step explanation:

First oval is a domain, second oval is a range.

To be a function, only one arrow should be from each number in domain,

but we have two arrows from number 6 and two arrows from the number 12. So, it is not a function.

false because,the x is repeating x.their are 2 arrows are pointing to the same number.

Step-by-step explanation:

how to tell if it is not a function

1)if x intercept is pointing to two numbers it is not a function

example:6 it is pointing at 2 and 4 so it would not be a function
