Substitute the values for a, b, and c into b2 – 4ac to determine the discriminant. Which quadratic equations will have two real

adoni [48]

Step-by-step explanation

<h3>Prerequisites:</h3>

$b^2 - 4ac = 0 \Rightarrow 1 solution$

$b^2 - 4ac > 0 \Rightarrow 2 solutions$

$b^2 - 4ac < 0 \Rightarrow No\ real\ solutions$

----------------------------------------------------------------

$2x^2-7x-9 = 0$

$b^2 - 4ac$

$-7^2 - 4(2)(-9) = 121$

2 Solutions

---------------------------------------------------------------

$x^2-4x+4 = 0$

$b^2 - 4ac$

$-4^2 - 4(1)(4) = 0$

1 Solution

---------------------------------------------------------------

$4x^2-3x-1 = 0$

$b^2 - 4ac$

$-3^2 - 4(4)(-1) = 25$

2 Solutions

---------------------------------------------------------------

$x^2-2x-8 = 0$

$b^2 - 4ac$

$-2^2 - 4(1)(-8) = 36$

2 Solutions

---------------------------------------------------------------

$3x^2+5x+3 = 0$

$b^2 - 4ac$

$5^2 - 4(3)(3) = -11$

No Solutions

Write the equation of the line that is parallel to the line 7 − 4 x = 7 y 7−4x=7y through the point (2,0).

lisov135 [29]

7 - 4x = 7y
1 - 4/7x = y....y = -4/7x + 1...slope here is -4/7.
A parallel line will have the same slope

y = mx + b
slope(m) = -4/7
(2,0)...x = 2 and y = 0
now sub and find b, the y int
0 = -4/7(2) + b
0 = -8/7 + b
8/7 = b

so ur parallel equation is : y = -4/7x + 8/7 <=
