1. How do you define quadratic equations?

oksian1 [2.3K]

Answer:

$ax^{2} +bx+c^{2}=0$

Step-by-step explanation:

A quadratic equation is a equation that takes the form: $ax^{2} +bx+c^{2} = 0$

Ex. Using our definition of quadratic equations, $ax^{2} +bx+c^{2}=0$ ,

We can set a = 2, b = 1, c = 6:

$2x^{2} +x+6^{2}=0$

$2x^{2} +x+36=0$

Which can then be solved (if you are trying to solve it) as:

$(2x+9)(x-8)=0$

$x=\frac{9}{2}, 8$

Write -5x-12y=12 in slope intercept form

TiliK225 [7]

Answer:

y = (-5/12)x - 1

Step-by-step explanation:

The fastest way in which to express -5x-12y=12 in slope-intercept form is to solve -5x-12y=12 for y:

Add 5x to both sides, obtaining -12y = 12 + 5x.

Next, divide both sides by -12, obtaining y = -1 - (5/12)x, or y = (-5/12)x - 1.

In pentagon $MATHS$, $\angle M \cong \angle T \cong \angle H$ and $\angle A$ is supplementary to $\angle S$. How many degrees ar

gavmur [86]

Answer:

H = 120°

Step-by-step explanation:

The sum of the internal angles of a polygon with n sides is given by the formula:

S = (n-2)*180

So, for a pentagon, we have n = 5, then:

S = (5-2)*180 = 540°

So we have that:

M + A + T + H + S = 540° (eq1)

M = T = H (eq2)

A + S = 180° (eq3)

Using the second and third equation in the first one, we have:

H + H + H + 180 = 540

3H = 360

H = 120°
