What is the equation of the line of reflection that - 1

Answers

Answer 1
Answer:

Triangle ABC was reflected along the y axis, to produce triangle A'B'C'

Transformation

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

If a point A(x, y) is reflected along the y axis, the new point is A'(-x, y).

The vertex of triangle ABC is at A(-1, -1). B(-2, -1) and C(-2, -4). If triangle ABC is reflected along the y axis, the new point is at A'(1, -1). B'(2, -1) and C'(2, -4)

What is 5.5 as an improper fraction?

Answers

 Three ways 
5.5 = 5 + .5 = 5 5/10 = 5 1/2 

5.5 = 55/10 = 11/2 = 5 1/2 

5.5 = 5 1/2 <---- at some point you'll need to know that 0.5 = 1/2

The data represent the number of phone calls received over a 70day period.Day 1 2 3 4 5 6 7
Calls Received 5 2 9 8 3 1 0

What is the mean number of phone calls received?

Answers

Are you talking about 7-day period instead? Or is that really 70? 

Anyway, the mean number of phone calls received over the period of time given would be 4 calls. I got to this answer through adding all of the calls and dividing them by the number of days. 

Four employees can wash 20 service vehicles in 5 hours. how long would it tke 5 employees to wash the same number of vehicles?

Answers

So the employee rate for washing cars turns out to be 4*5 = 20 man hours to wash 20 vehicles which is 1 vehicle per hour per employee. 
5 employees will wash 5 vehicles in 1 hour 
5 employees will wash 20 vehicles in 1*4 = 4 hours.

For the quadratic trinomial ax^2+bx+c the following formula

ax^2+bx+c=a(x-x_1)(x-x_2), where x_1, x_2 are trinomial roots, holds.

1. For trinomial 6x^2 - 13x - 5 find the roots:

.

2. The factoring form is

6x^2-13x-5=6\left(x+(1)/(3)\right)\left(x-(5)/(2)\right) =(3x+1)(2x-5)

Answer: correct option is B.
to FL and add
multiply first terms and multiply last terms and add and see if we get the middle term
example
(x+2)(2x-3)=2x^2+x-6x
2*2x+x*-3=4x-3x=x=middle term so



a. (2x+5)(3x-1)
2x*-1+5*3x=-2x+15x=13x, no we want -13x

b. (2x-5)(3x+1)
2x*1+-5*3x=2x-15x=-13x correct



answer is B
