Answer:
1 ans 6
2 ans 4
3 ans 8
because if x equals zero then its basic arithmetic
for the 0 u put zero the for 5 u put 40 then for 10 u put 80 then for 15 u put 120 then for 20 u put 160
Y=-2x+0 reason: rise over run as you can see in the graph -2 rise (drop) and -1 run and b=0 y intercept
There are 10 fish in the tank
<em><u>Solution:</u></em>
Given that, volume of a tank is 50 cubic feet
Density is 0.2 fish over feet cubed
<em><u>To find: Number of fish in the tank</u></em>
Number of fish in the tank is found by multiplying the volume of tank and density
<em><u>The formula is given by:</u></em>
![\text{Number of fish} = \tex{\text{volume of tank}} \times {\text{density of fish over feet cubed}}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20fish%7D%20%3D%20%5Ctex%7B%5Ctext%7Bvolume%20of%20tank%7D%7D%20%5Ctimes%20%7B%5Ctext%7Bdensity%20of%20fish%20over%20feet%20cubed%7D%7D)
<em><u>Substituting the given values, we get</u></em>
![\text{Number of fish} = 50 ft^3 \times \frac{\text{ 0.2 fish}}{ft^3}\\\\ \text{Number of fish} = 50 \times 0.2 \text{ fish }\\\\ \text{Number of fish} = 10 \text{ fish }](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20fish%7D%20%3D%2050%20ft%5E3%20%5Ctimes%20%5Cfrac%7B%5Ctext%7B%200.2%20fish%7D%7D%7Bft%5E3%7D%5C%5C%5C%5C%20%5Ctext%7BNumber%20of%20fish%7D%20%3D%20%2050%20%5Ctimes%200.2%20%5Ctext%7B%20fish%20%7D%5C%5C%5C%5C%20%5Ctext%7BNumber%20of%20fish%7D%20%3D%2010%20%5Ctext%7B%20fish%20%7D)
Thus there are 10 fish in the tank
