Let a, b, c, and d be non-zero real numbers. If the quadratic equation ax(cx + d) = -b(cx+d) is solved for x, which of the follo

LiRa [457]

Answer:

Option d

Step-by-step explanation:

given that a, b, c, and d be non-zero real numbers.

$ax(cx + d) = -b(cx+d) \\acx^2+x(ad+bc)+bd =0$

we can factorise this equation by grouping

$(acx^2+xad)+)xbc+bd) =0\\ax(cx+d) +b(cx+d) =0\\(ax+b)(cx+d) =0$

Equate each factor to 0 to get

$x=\frac{-b}{a} , \frac{-d}{c}$

Ratio of one solution to another would be

$\frac{-b}{a} / \frac{-d}{c} \\=\frac{ad}{bc}$

So ratio would be ad/bc

Out of the four options given, option d is equal to this

So option d is right

Write an equation for the parabola who’s vertex is at (3,6) and which passes through (4,4)

Gekata [30.6K]

Problem

Solution

For this case we know that the vertex is given by (3,6) and the genera equation for a parabola is given by:

y= a(x-h)^2 +k

Where h = 3, k=6 and replacing we have:

y= a(x-3)^2 +6

And we can find the value of a with the point given x= 4, y=4

4= a(4-3)^2 +6

4= a +6

a= 4-6=-2

And the correct equation would be:

d. y= -2(x-3)^2 +6
