Use the discriminant (b^2-4ac)
a=1, b=0, c=-7
0^2-4(1)(-7)
0-4(-7)
0+28
28
Since 28>1, there are 2 solutions.
Final answer: B
Write the fractions in ascending order: 1/4, 2/8 (same as 1/4), 3/4 and 4/8 (same as 1/2). 3/4 is greater than 1/4, greater than 2/8 and greater than 4/8, so Audrey, at 4/8, at the most.
Answer:
To make given quadratic equation a whole number , we have to add 6 in the equation.. (3 x - 4 )²
Step-by-step explanation:
The given quadratic equation is
9 x² - 24 x + 10 = 0
(3 x )² - 24 x + 10 = 0
(3 x )² - ( 2 × 3 x × 4 ) + 10 = 0
Now if we add 6 to the equation , it will become whole square as (a + b)²
I.e (3 x )² - ( 2 × 3 x × 4 ) + 10 + 6 = 0
Or, (3 x )² - ( 2 × 3 x × 4 )+ 16 = 0
Or, 9 x² - 24 x + 16 = 0
Or, (3 x - 4 )² = 0
Hence to make given quadratic equation a whole number , we have to add 6 in the equation.. Answer
Answer:
Answer c:
Step-by-step explanation:
Hi there!
Let´s start writting the formula
If we multiplicate both sides by (x₂ - x₁):
Then if we add y₁ to both sides of the equation:
Then, the right answer is the answer c)
Have a nice day!
Answer:
4
Step-by-step explanation:
f(x) = 3x - 1, g(x) = 2x - 3
f(2) = 3(2) - 1 = 6 - 1 = 5.
If g(x) = f(2).
2x - 3 = 5
2x = 8
x = 4. This value ensures g(x) = f(2).
