Which equation can be solved by using this expression?

Marat540 [252]

Answer:

The correct answer option is B. 2 = 3x + 10x^2

Step-by-step explanation:

We are to determine whether which of the given equations in the answer options can be solved using the following expression:

$x=\frac{-3 \pm\sqrt{(3)^2+4(10)(2)} }{2(10)}$

Here, $a = 10, b = 3$ and $c=-2$ .

These requirements are fulfilled by the equation 4 which is:

$12=3x+10x^2$

Rearranging it to get:

$10x^2+3x-2=0$

Substituting these values of $a,b,c$ in the quadratic formula:

$x= \frac{-b \pm \sqrt{b^2-4ac} }{2a}$

$x= \frac{-3 \pm\sqrt{(3)^2-4(10)(-2)} }{y}$

The lines graphed below are parallel. The slope of the red line is -4/3. What is the slope of the green line?

miss Akunina [59]

I believe the correct answer from the choices listed above is option C. The slope of the green line would be -4/3. Parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point. These lines should have equal slopes. Hope this answers the question.
