Y = x² - 3x - 18

When y = 0,

x² - 3x - 18 = 0

<span>(x + 3)(x - 6) = 0
</span>
x = -3 or x = 6

Find the value of x. I WILL GIVE YOU BRAINLIEST!!!!

Elan Coil [88]

Hi there!

$\large\boxed{x = 40}$

We can solve for x knowing that the sum of interior angles in a triangle is 180°.

The square at the bottom indicates a right angle, or 90°. Therefore:

180 = 90 + x + (x + 10)

Combine like terms:

180 = 100 + 2x

Subtract 100 from both sides:

180 - 100 = 2x

80 = 2x

Divide both sides by 2:

x = 40.

Of the 30 people in Miss Hall’s class, 65% are walking home after school. Which of the following is equivalent to 65%? A. 65 B.

AlekseyPX

65% means 65/100, or 65 100ths.

Converting a number from a ratio/fraction, such as 65/100, just involves dividing the numerator by the denominator.

65 ÷ 100 = 0.65

Answer is 0.65

Prove: The segments joining the midpoints of the opposite sides of a quadrilateral bisect each other.

zhuklara [117]

Answer:

$R=(\dfrac{b}{2},0)$

$S=(\dfrac{b+c}{2},\dfrac{d}{2})$

$T=(\dfrac{c+e}{2},\dfrac{d+f}{2})$

$U=(\dfrac{e}{2},\dfrac{f}{2})$

$M=(\dfrac{b+c+e}{4},\dfrac{d+f}{4})$

$M=(\dfrac{c+b+e}{4},\dfrac{d+f}{4})$

Step-by-step explanation:

We are given coordinates as:

$A(0,0)\ ,\ B=(b,0)\ ,\ C=(c,d)\ ,\ D=(e,f)\\\\R=(\dfrac{b}{2},0)\ ,\ S=(\dfrac{b+c}{2},\dfrac{d}{2})\ ,\ U=(\dfrac{e}{2},\dfrac{f}{2})\ ,\ T=(\dfrac{c+e}{2},\dfrac{d+f}{2})$

Now, it is given that M is the mid-point of the line segment RT and of US.

Hence, the coordinates of M is given as:

By taking the mid-point of side RT.

$M=(\dfrac{\dfrac{b}{2}+\dfrac{c+e}{2}}{2},\dfrac{0+\dfrac{d+f}{2}}{2}})\\\\\\i.e.\\\\\\M=(\dfrac{b+c+e}{4},\dfrac{d+f}{4})$

By taking the mid-point of side US.

$M=(\dfrac{\dfrac{e}{2}+\dfrac{b+c}{2}}{2},\dfrac{\dfrac{f}{2}+\dfrac{d}{2}}{2})\\\\\\i.e.\\\\\\M=(\dfrac{b+c+e}{4},\dfrac{d+f}{4})$
