Answer:
There are 15 koi
Step-by-step explanation:
koi: goldfish : total
3 11 14
There are 70 fish total
70/14 = 5
Multiply each term by 5
koi: goldfish : total
3*5 11*5 14*5
15 55 70
There are 15 koi
Answer:
7 x - y = 48 is the required line equation.
Step-by-step explanation:
Here,the two given points are A(6,-6) and B(8,8).
Now, the slope of the line with points (x1,y1) and (x2,y2) is given as:
![m = \frac{y_2 -y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-y_1%7D%7Bx_2-x_1%7D)
So, here the slope of the given line is ![m = \frac{(8-(-6))}{8-6} = \frac{8+6}{2} = 7](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B%288-%28-6%29%29%7D%7B8-6%7D%20%20%3D%20%5Cfrac%7B8%2B6%7D%7B2%7D%20%20%20%3D%207)
or , m = 7
Now, by POINT SLOPE FORMULA:
The equation of a line with point (x0,y0) and slope m is given as:
(y- y0) = m (x -x0)
⇒ Here, the equation of line with (8,8) is y - 8 = 7 (x -8)
or, y - 8 = 7 x - 56
or, 7 x - y = 48 is the required line equation.
