First notice that f(x) is negative, so entire graph will be below x-axis.
Next find domain by setting what is inside sqrt greater than 0.
You can't take sqrt of neg number.
Finally plot some points, start at x = 1, y=0.
Then try x = 0, y = -1.
x = -3, y = -2.
Connect the points, done.
Answer:
The scale factor is 1.5
Step-by-step explanation:
Given
Required
Determine the scale factor
From the question, we have that:
1. DEF is the original triangle and ABC is only its scale factor
2. AB and DE are the longest sides in both triangles
(2) implies that, AB is a translation of DE
The scale factor is calculated as follows
Where k is the scale factor;
Substitute values for AB and De
Hence:
<em>The scale factor is 1.5</em>
Answer:
28/3 , - 11/3
Step-by-step explanation:
let the first number be x and second be y.
here,
1st case
x + 2y = 2
x= 2 - 2y ............(i)
2nd case
2x + y = 13
x = 13 - y / 2 .............(ii)
from equation i and ii
we get,
(2 - 2y ) 2 = 13-y
4 - 4y = 13 - y
4 - 13 = 4y - y
- 11 = 3y
y = - 11 / 3
now,
putting the value of y in equation( i )we get,
x = 2 - 2 * -11 / 3
=6 + 22/ 3
=28 / 3
Answer: always
Step-by-step explanation:
Divide the length of the wall by 2 to find the middle:
73 1/2 / 2 = 36 3/4 inches.
