Answer:
160 Points in 5 Games
Step-by-step explanation:
The given information will be used as the first ratio. 288 points / 9 games. To find out how many points this player would score in 5 games, we use another ratio with the unknown value, x. This would be x points / 5 games. Put the ratios equal to each other and cross multiply. You will get a final answer of 160.
Answer: Actually, you must use the Pythagorean Theorem!
a squared plus b squared equals c squared. So if you substitute in the values, a is 2 units and b is three units. 2 squared is 4 and 3 squared is 9.
4 + 9 = 13 so the answer is the square root of 13. (√13)
Assumed that sides are equal
- 5x-3=3x+1
- 5x-3x=1+3
- 2x=4
- x=2

Answer: β ≠ ±1
Step-by-step explanation: For a system of equations to have an unique solution, its determinant must be different from 0: det |A| ≠ 0. So,
det ≠ 0
Determinant of a 3x3 matrix is calculated by:
det
β ≠ ±1
For the system to have only one solution, β ≠ 1 or β ≠ -1.
y = 2 ( x + 3/4 )^2 − 25 8
