Mathematics

nasty-shy [4]3 years ago

Hello there!

First of all, I like your profile picture!

1) There's a lot of different methods for solving a system of equation. But here are my three favorite.

  • Graphing
  • Substitution (Which I preferred to use and I think it is easier).
  • Elimination

2) When solving a system of equations, you can get;

  • One solution
  • No solution
  • Infinite number of solution

3) The graphing method help solving a system of equation by knowing that the solution to a system of equations is the point of intersection of the two lines.

I hope this answer helps. As always, it is my pleasure helping student like you!

Bill plans to buy school supplies and the following equation represents what he bought.
iren2701 [21]

Answer:

1. x = 8

2. y = 1/2

Step-by-step explanation:

1. Plug the function

5x + 20(0.50) = 50

= 5x + 10 = 50

Subtract 10 from both side

= 5x = 40

Divide 5 on both sides

= x = 8

2. Plug in the function

5(8) + 20y = 50

= 40 + 20y = 50

Subtract 40 on both sides

= 20y = 10

Divide 20 both sides

= y = 10/20 | 1/2

Naddika [18.5K]

Answer:

There is a 25/81 probability that Grace will make both of her next two shots.

Step-by-step explanation:

The probability of her making the first shot is 5/9.

The probability of her also making the shot after that is still 5/9, that does not change.

To find the probability of both of those events, multiply the fractions.

5/9 * 5/9

25/81.
