Answer:
1/3
Step-by-step explanation:
The scale factor is the ratio of image lengths to original lengths. For this pair of figures, the scale factor is ...
A'B'/AB = 2/6 = 1/3
The scale factor is 1/3.
Answer:
B) y = x + 2 and y = -x - 4
Step-by-step explanation:
Let the equation of a straight line with x-intercept 'a' and y-intercept 'b' be
![\frac{x}{a} + \frac{y}{b} = 1](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7Ba%7D%20%20%2B%20%20%5Cfrac%7By%7D%7Bb%7D%20%20%3D%201)
The line with positive slope has x-intercept a=-2 and y-intercept b=2.
Its equation is:
![\frac{x}{ - 2} + \frac{y}{2} = 1](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B%20-%202%7D%20%20%2B%20%20%5Cfrac%7By%7D%7B2%7D%20%20%3D%201)
Multiply through by 2
![- x + y = 2](https://tex.z-dn.net/?f=%20-%20x%20%2B%20y%20%3D%202)
Solve for y,
![\boxed {y = x + 2}](https://tex.z-dn.net/?f=%20%5Cboxed%20%7By%20%3D%20x%20%2B%202%7D)
For the line with a negative slope,
the x-intercept is a=-4 and the y-intercept is b=-4
Its equation is
![\frac{x}{ - 4} + \frac{y}{ - 4} = 1](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B%20-%204%7D%20%20%2B%20%20%5Cfrac%7By%7D%7B%20-%204%7D%20%20%3D%201)
Multiply through by -4
![x + y = - 4](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%20%20-%204)
Solve for y
![\boxed {y = - x - 4}](https://tex.z-dn.net/?f=%20%5Cboxed%20%7By%20%3D%20%20-%20x%20-%204%7D)
Answer:
a number that is divisible only by itself and 1 (e.g. 2, 3, 5, 7, 11).
Step-by-step explanation:
Each person gets 1 1/4 bars.
You divide the 5 bars by 4 people: 5/4 = 1 1/4
