Answer:
x = 4 or x = (-3)/2
Step-by-step explanation:
Solve for x over the real numbers:
2 x^2 - 5 x - 12 = 0
x = (5 ± sqrt((-5)^2 - 4×2 (-12)))/(2×2) = (5 ± sqrt(25 + 96))/4 = (5 ± sqrt(121))/4:
x = (5 + sqrt(121))/4 or x = (5 - sqrt(121))/4
sqrt(121) = sqrt(11^2) = 11:
x = (5 + 11)/4 or x = (5 - 11)/4
(5 + 11)/4 = 16/4 = 4:
x = 4 or x = (5 - 11)/4
(5 - 11)/4 = -6/4 = -3/2:
Answer: x = 4 or x = (-3)/2
Answer: 4 games
Step-by-step explanation:
The team has won 6 games and lost 4 games. The win--loss ratio at the moment must be:
= 6 : 4
This must be at its simplest form which is:
= 3 : 2
To take it to 5 : 2, we would have to take up the left side of the ratio by 2.
Because we simplified by using a factor of 2, we have to multiply the 2 we just calculated by the factor to find the number of games needed to be won:
= 2 * 2
= 4 games
That is false. The parabola opens to the right.
Answer:
A. Bananas
Step-by-step explanation:
Bananas = 8
Oranges = 3
Apples = 5
Kiwis = 6
For every 3 kiwis, there are 4 ______
Kiwi : bananas = 6 : 8
6 : 8 = 6/8
= 3 / 4
= 3 : 4
Kiwi : oranges = 6 : 3
= 6 / 3
= 2 / 1
= 2 : 1
Kiwi : apples = 6 : 5
For every 3 kiwis, there are 4 bananas
A. Bananas
