We use the following reflection rule:
(x, y) = (x + 1, y)
We have then:
M (-3, 1) ---> M '(- 2, 1)
O (1, 4) ---> O '(2, 4)
P (3, -1) ----> P '(4, -1)
Answer:
The new vertices are
M '(- 2, 1)
O '(2, 4)
P '(4, -1)
Graph five (last from left to right) is the correct one.

A triangle has vertices at (-9,2), (-9,-6), (-3,-6). What is the perimiter of the triangle in units?

vladimir2022 [97]

Answer:

The perimeter is 24 units

Step-by-step explanation:

Given

$A = (-9,2)$ --- $(x_1,y_1)$

$B = (-9,-6)$ --- $(x_2,y_2)$

$C = (-3,-6)$ --- $(x_3,y_3)$

Required

Determine the perimeter

To do this, we calculate the distance AB, BC and AC.

Distance is calculated as:

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2$

So, we have:

$AB = \sqrt{(-9 - -9)^2 + (2 - -6)^2$

$AB = \sqrt{64$

$AB = 8$

$BC = \sqrt{(-9 - -3)^2 + (-6 - -6)^2$

$BC = \sqrt{36$

$BC = 6$

$AC = \sqrt{(-9 --3)^2 + (2 --6)^2$

$AC = \sqrt{100$

$AC = 10$

So, the perimeter (P) is:

$P = AB + BC + AC$

$P =8 + 6 + 10$

$P =24$

If alpha beta are the roots of the equation

Vikki [24]

Answer:

Step-by-step explanation:

Hello, I believe that we can consider a different from 0.

By definition of the roots we can write.

$ax^2+bx+c=a(x-\alpha)(x-\beta)=a(x^2-(\alpha + \beta)x+\alpha \cdot \beta)\\\\\text{So we can say that:}\\\\\alpha + \beta = \dfrac{-b}{a}\\\\\alpha \cdot \beta=\dfrac{c}{a}\\\\\text{So the expected quadratic equation is}\\\\(x+\dfrac{b}{a})(x-\dfrac{c}{a})=0\\\\ \Large \boxed{\sf \bf \ (ax+b)(ax-c)=0 \ }$

Thank you

A bag contains 7 red marbles, 8 blue marbles, and 9 green marbles. What is the probability of choosing a blue marble when one ma

lana66690 [7]

So to find probability you would have to add together all of the marbles in the bag (7+8+9=24) and then find the fractional probability of drawing blue marbles out of all the marbles in the bag. So 9/24

Write an equation that represents the tile pattern in the table below

natima [27]

Answer:

y=3x+2

Step-by-step explanation:

First find the slope or m in the line of equation y=mx+b

to find slope you need two points, plug in to y2-y1 / x2-x1

so lets use points (0,2) (1,5)

5-2 / 1-0 = 3

m=3

we have y=3x + b

now we find b by pugging in a point, let's use (0,2)

2 = 3(0) + b

b= 2

y=3x+2
