Determine the type and number of solutions of 4x^2-5x+1=0.A. Two real solutions
B. One real solution
C. Two imaginary solutions

Answers

Answer 1
Answer: 4x² - 5x + 1 = 0
a = 4; b = - 5, c = 1
Δ = b² - 4.a.c
Δ = (-5)² - 4.4.1
Δ = 25 - 16
Δ = 9

x = - b ± √Δ / 2.a
x = (-5\± √(9) )/(2*4)
x = (-5\±3)/(8)
x' = (-5-3)/(8) = (-8)/(8) = -1
x' = (-5+3)/(8) = (-2)/(8) (/2) = (-1)/(4)


A. Two real solutions (x' = -1 and x'' = -1/4)

b. Points are plotted at (two, two), (two, eight), (four, three), (five, one), (six, three), (seven, five), (eight, six), (nine, two). I'm really confused can you please help me

Answers

Variable A - horizontal axis ⇒ xVariable B - vertical axis ⇒ y
points (x, y)       A      B1)    2 ,    22)    2 ,    83)    4 ,    34)    5 ,    15)    6 ,    36)    7 ,    5 7)    8 ,    68)    9 ,    2

Median of a set of data is the middlemost number in the set. We need to arrange the numbers in order from least to greatest and find the middlemost number of the set.

B = 2, 8, 3, 1, 3, 5, 6, 2

There are 8 numbers that we need to arrange in order.

1, 2, 2, 3, 3, 5, 6, 8

Since the data set is even. We need to look for the middle two numbers and find its average.

3 + 3 = 6 
6 ÷ 2 = 3 IS THE MEDIAN of Variable B.
