Answer:

The given line segment has a midpoint at (−1, −2).

On a coordinate plane, a line goes through (negative 5, negative 3), (negative 1, negative 2), and (3, negative 1).

What is the equation, in slope-intercept form, of the perpendicular bisector of the given line segment?

y = −4x − 4

y = −4x − 6

y = One-fourthx – 4

y = One-fourthx – 6

y = Three-halvesx + 1

(X+9)(x-2)-9x-6 is equivalent to?

Allushta [10]

Answer:

$x^{2}$ - 2x - 24

Step-by-step explanation:

(x + 9)(x - 2) - 9x - 6

$x^{2}$ - 2x + 9x - 18 - 9x - 6 Multiply.

$x^{2}$ - 2x - 24 Combine the like terms.

Calculate the side lengths a and b to two decimal places.

Zinaida [17]

Answer:

$a=10.92 units$

$b=14.51 units$

Step-by-step explanation:

We are given that c=6 units

$\angle A=43^{\circ}$

$\angle B=115^{\circ}$

We have to find the side length a and b.

We know that sum of angles of a triangle =180 degrees

$\angle A+\angle B+\angle C=180$

Substitute the values then we get

$43+115+\angle C=180$

$158+\angle C=180$

$\angle C=180-158=22^{\circ}$

sine law: $\frac{a}{sin A}=\frac{b}{sin B}=\frac{c}{sin C}$

$\frac{a}{sin 43^{\circ}}=\frac{6}{sin 22^{\circ}}$

$a=\frac{6}{sin 22^{\circ}}\times sin 43^{\circ}$

$a=10.92 units$

$\frac{b}{sin 115^{\circ}}=\frac{6}{sin 22^{\circ}}$

$b=\frac{6}{sin 22^{\circ}}\times sin 115^{\circ}=14.51$

$b=14.51 units$

A square has an area of 9yd^2. What is the length of each side?

BlackZzzverrR [31]

Answer: The side length is 3 yards.

Step-by-step explanation:

To find the area of a square, you have to square one of it's side lengths since they all share the same length. Since we know the area, and we need to find the side length so we just need to find the square root of the area.

$\sqrt{9}$ = 3

The side length is 3 yards.

You survey 200 people about the electronics they own. The results show that 33/40 people own a cell phone. Of these people, 10/1

guajiro [1.7K]

200 * 33/40 = 165 owns phones
165 * 10/11 = 150 owns phones and MP3 player

Therefore 3/4 owns both and
165 owns only phones
