Answer:
The scale factor from figure A to figure B is 2.
Step-by-step explanation:
See the attached diagram.
In the diagram shown figure A and figure B are similar and the two quadrilateral have side lengths that are in the same proportion.
If we want to identify the ratio of side lengths of figure B to corresponding side lengths of figure A, then it is constant and
![\frac{44}{22} = \frac{20}{10} = \frac{64}{32} = \frac{80}{40} = 2](https://tex.z-dn.net/?f=%5Cfrac%7B44%7D%7B22%7D%20%3D%20%5Cfrac%7B20%7D%7B10%7D%20%3D%20%5Cfrac%7B64%7D%7B32%7D%20%3D%20%5Cfrac%7B80%7D%7B40%7D%20%3D%202)
Therefore, the scale factor from figure A to figure B is 2. (Answer)
Answer:
y=-2x-94
Step-by-step explanation:
You can do anything with the y-intercept. The line is parallel (same slope) and the y-intercept can be literally any number in the world. I would advise to not use negative or positive infinity though.
Answer:
DF = 57
Step-by-step explanation:
DE + EF = DF
(4x + 10) + (2x - 1) = 9x - 15
Combine like terms on the left side
6x + 9 = 9x - 15
Subtract 6x on both sides
9 = 3x - 15
Add 15 on both sides
24 = 3x
Divide by 3 on both sides
x = 8
DF = 9x - 15 = 9(8) - 15 = 72 - 15 = 57
Checking:
(4(8) + 10) + (2(8) - 1) = 9(8) - 15
(32 + 10) + (16 - 1) = 72 - 15
58 - 1 = 72 - 15
57 = 57
Answer: 250% of 44 is greater than 100 but less than 150.
Why:
250/100 = 2.5
2.5 is 250% in decimal form.
2.5 * 44 = 110
110 is less than 150, but greater then 100.
