Your answer is A) (1,1) is the solution to both lines K and J

That's because the solution to a system of equations has to be the solution to both of the lines. Also, both of the lines intersect at the point (1,1).

Look at the graph and look where the point lyes.
It lyes on 1,1. They intersect at 1,1.Your answer will be A.

Answer:

D. Infinitely many solutions

Step-by-step explanation:

The equation simplifies to ...

2h -16 -h = h -16

h -16 = h -16 . . . . . . a "tautology", true for all values of h.

There are infinitely many solutions.

you have 3.75 to spend at a vending machine. You want to buy at least three health bars. Regualr health bars cost 0.75 each and

DedPeter [7]

Answer:

Let x be the number of regular health bars you buy and y the number of strawberry health bars you buy. Then:

0.75x+1.25y=3.75

x+y>=3

Step-by-step explanation:

For the first equation, we have to assume that you will spend all of your money, otherwise it becomes an inequation. The money you spend on regular bars is 0.75x dollars and the money you spend on strawberry bars is 1.25y, so if you spend your 3.75 dollars on the bars, then 0.75x+1.25y=3.75.

For the second, you will always buy x+y health bars, regular and strawberry. There isn't enough information to make this into a equation, the only thing we can deduce is the inequation x+y>=3.

If we also assume that x and y are integers (we can't buy half-bars or one-fourth of a bar) then the minimum number of bars we can buy is 3 (3 strawberry bars) and the maximum is 5 bars (5 regular bars). x+y must be an integer too, so the possibilities for the second equation are x+y=3, x+y=4 and x+y=5. There is a finite number of solutions in any case.

I next help on the polynomial

slamgirl [31]

Answer:

u just have to cross multiply im pretty sure thats how my math teacher show me,

Step-by-step explanation:

first you take the one x over to the other x and that will make it 2x then do the same thing with -10 u do -10 times 10 and then u get -100 and then the answer is 2x-100 and depending on your teach if he/she wants you to stop their then u can but if u have to got further then u would divide 2 on both sides and then that would be 0.02

this is how my teacher showed us how to do it and i hope this helps you a lot and if it dont im sorry i tried for you!!!

have a nice day Hun
