Algebra I

Coordinates (x, y)
Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define System

4x + 2y = -1

3x + 4y = 3

Step 2: Rewrite System

4x + 2y = -1

[Multiplication Property of Equality] Multiply -2 on both sides: -2(4x + 2y) = 2
[Distributive Property] Distribute -2 on both sides: -8x - 4y = 2

Step 3: Redefine Systems

-8x - 4y = 2

3x + 4y = 3

Step 4: Solve for x

Combine equations: -5x = 5
[Division Property of Equality] Divide -5 on both sides: x = -1

Step 5: Solve for y

Substitute in x [Original Equation]: 3(-1) + 4y = 3
Multiply: -3 + 4y = 3
[Addition Property of Equality] Add 3 on both sides: 4y = 6
[Division Property of Equality] Divide 4 on both sides: y = 3/2

No woman has broken the 10-second barrier in the 100 -meter runfind probability the empirical probability that a womwn will brea

Anuta_ua [19.1K]

Let me help you!

What we have so far:
Number of times the event occured = 0
Total number of times the event was performed = 0

We will use the empirical probability formula for this problem:
Empirical probability formula = Number of times the event occured / Total number of times the event was performed

Solving for the porblem:
Empirical probability formula = 0.

*** Without even solving the problem, you can take the word "NO" as a hint that there's simply no chance any woman can beak the 10 seconds barrier in a 100 meter run.

Therefore, there is 0 probability that a woman will break the 10 seconds barrier in a 100 meter run.
