Answer:
The discriminant is 0
There is 1 real solution
Step-by-step explanation:
Use the discriminant formula, D = b² - 4ac
In the equation y = x² - 4x + 4, a is 1, b is -4, and c is 4.
Plug in these values into the formula:
D = b² - 4ac
D = (-4)² - 4(1)(4)
D = 16 - 4(4)
D = 16 - 16
D = 0
So, the discriminant is 0.
With a discriminant of zero, there is one real solution.
So, the number of real solutions is 1.
We know that they're 12(in) in a foot.
So, if we were to divide them, we would then get 12 feet, and also 25th of 12(in).
Answer:
-1
Step-by-step explanation:
Can you put picture, it is not clear
The slope equals to 4
By rearranging the equation to be this : y=4x-5.5
