Answer:

x = 11

Step-by-step explanation:

4x + 7 = 6x -15

4x - 6x = -15-7

-2x = -22 / : (-2)

x = 11

Bradley and Louie are roommates at college. At the beginning of the semester, they each paid a security deposit of A
Pie

An expression that describes how much each person will receive from the landlord when the lease expires is; A - (B/2) = R. And the amount received by each person as described is; $100

Since, Bradley and Louie are expected to each pay a security deposit of A;

  • In essence, amount paid by each person is; A

Since, the total expenses = B and is to be shared by Bradley and Louie equally; we have;

  • Each person pays expenses charge; B/2.

An expression that describes how much each person will receive from the landlord when the lease expires is;

  • <em>A - (B/2) = R</em>.

Ultimately, when each person pays, A = $125 and damages charge = $50;

The amount received by each person is;

  • R = 125 - (50/2)

R = $100

Graphing help please - fairly simple, image attached.
alisha [4.7K]
To figure out if a graph is a function, you can use this thing called the vertical line test. in case you're unfamiliar, it's basically where you just imagine a vertical line going from left to right on the graph. if it crosses the function in two places, it's incorrect. i suggest looking up a video that shows you a visual representation of the vertical line test if you've never heard of it; it's fairly simple.

A is a function because the graph passes the vertical line test. if you imagine a vertical line and drag it from left to right across the graph, the linear function graphed in choice A does not have two x values at the same spot.

B is not a function. it fails the vertical line test almost immediately: the sideways "U" shapes makes it intersect the vertical line twice in one place.

C is a function. it passes the vertical line test, even though it looks a little strange. at no point does it intersect the vertical line twice.

D is a function. again, it doesn't intersect the vertical line twice.

now, to determine if a function is a one-to-one function, it must also pass the horizontal line test. this means that it doesn't intersect at two points horizontally as well. test that out on choices A, C, and D.

A is a one-to-one function because it doesn't cross in the same place horizontally, either. C and D are one-to-one functions as well.
