Answer:
X=14
Step-by-step explanation:
Well 3/8 is .375 but times 100 is 37.5%
Then 37.5% of 800 is 300
Answer:
x=13
Step-by-step explanation:
6x-15-4x=11
2x-15=11
2x=26
x=13
Answer:
Option (1) will be the answer.
Step-by-step explanation:
Coordinates of the points A and B lying on the line f are (0, 2) and (2, 0) respectively.
Slope of the line f,
![m_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=m_%7B1%7D%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
![m_{1}=\frac{2-0}{0-2}](https://tex.z-dn.net/?f=m_%7B1%7D%3D%5Cfrac%7B2-0%7D%7B0-2%7D)
After dilation of line f by a scale factor of 2, coordinates of A' and B' will be,
Rule for dilation,
(x, y) → (kx, ky)
Where k = scale factor
A(0, 2) → A'(0, 4)
B(2, 0) → B'(4, 0)
Slope of line f',
![m_{2}=\frac{0-4}{4-0}](https://tex.z-dn.net/?f=m_%7B2%7D%3D%5Cfrac%7B0-4%7D%7B4-0%7D)
![m_{2}=-1](https://tex.z-dn.net/?f=m_%7B2%7D%3D-1)
Since, ![m_{1}=m_{2}=-1](https://tex.z-dn.net/?f=m_%7B1%7D%3Dm_%7B2%7D%3D-1)
Therefore, both the lines f and f' will be parallel.
Option (1) will be the answer.
