Answer:
Kalpana = 49
Abhilasha = 77
Gouri = 16
Step-by-step explanation:
You can write this as an equation, where Kalpana is x, to make it easier to understand.
Gouri + 33 = x
Gouri = x - 33
Abhilasha - 28 = x
Abhilasha = x + 28
Now just plug in 49.
49 - 33 = 16
49 + 28 = 77
A) x = 3
b) x = -1
c) x = -9
d) x = 25
e) x = 8
f) x = -29
g) x = -1
h) x = 4/6
Answer:
Step-by-step explanation:
To find the slope, use 2 coordinates from your table and plug them into the slope equation, which is
![m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
Let's use the first 2 coordinates (-1, -2) and (0, -4). Plugging into the slope formula:
![m=\frac{-4-(-2)}{0-(-1)}=\frac{-4+2}{0+1}=\frac{-2}{1}=-2](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-4-%28-2%29%7D%7B0-%28-1%29%7D%3D%5Cfrac%7B-4%2B2%7D%7B0%2B1%7D%3D%5Cfrac%7B-2%7D%7B1%7D%3D-2)
Therefore, we know that the slope is -2.
The y-intercept exists where x = 0. We see from our table that when x = 0, y = -4. So the y-intercept is -4.
To write our equation, we will use the slope-intercept form of a line, which is
y = mx + b, where m is the slope and b is the y-intercept. Plugging in both our values for slope and the y-intercept:
y = -2x - 4
C because it is 1/7 because that is the best answer good luck :)
