Y = x² + 4x - 5
y = 2x
x² + 4x - 5 = 2x
<u> - 2x - 2x</u>
x² + 2x - 5 = 0
x = <u>-(2) ± √((2)² - 4(1)(-5))</u>
2(1)
x = <u>-2 ± √(4 + 20)</u>
2
x = <u>-2 ± √(24)
</u> 2
x = <u>-2 ± 2√(6)</u>
2
x = -1 ± √(6)
x = -1 + √(6) U x = -1 - √(6)
y = 2x
y = 2(-1 ± √(6))
y = 2(-1) ± 2√(6)
y = -2 ± 2√(6)
(x, y) = (-1 ± √(6), -2 ± 2√(6))

Answer:
You will have a 1/6 probability of getting a 2 that will land face up on the next roll.
Step-by-step explanation:
There is only one two on the cube, which means you will have 1 chance out of 6 of getting a 2.
Assuming you meant
Then you can compose the function g(x)
With the function
Because f (g(x) ) means that you first find (calculte)
and second you divide 7 by g(x) to obtain 7 / [√(8x+10) ].
Answer:
2.8 if rounded, If not rounded, 2.77
