Answer:

The x-intercept tells the number of fish in the tank before any are sold.

Coordinates (20, 80) tell how many fish must be sold to have 80 fish remaining in the tank.

Step-by-step explanation:

You should know here that, the graph models a decreasing function. Also, the average rate of the change of the function, and which is the slope is -1 as it has a negative slope. And hence the correct option for this question are not these two. The correct options are the ones mentioned above. As the x-intercept tells the number of fish in the tank before any of them are sold. And the coordinates (20, 80) tells the number of fish that must be sold for having the 80 fish remaining in the tank.

Answer:

I believe the answer is 40%

Step-by-step explanation:

The reasoning is 12+18=30 then you divide the amount of soldiers there is by the amount on toys in totality which is 12÷30 which is .4 convert to a percent which is 40%

Hence the answer is 40%

Step-by-step explanation:

Question 1)

We want a parabola that has the vertex (-8, -7) and also passes through the point (-7, -4).

So, we can use the vertex form. Remember that the vertex form is:

$y=a(x-h)^2+k$

Where a is our leading co-efficient and (h, k) is our vertex.

We know that our vertex is (-8, -7). So, substitute this into the equation:

$y=a(x-(-8))^2+(-7)$

Simplify:

$y=a(x+8)^2-7$

Now, we need to determine the value of our a. To do so, we can use the point the problem had given us. We know that the graph passes through (-7, -4).

So, when x is -7, y is -4. Substitute -7 for x and -4 for y:

$(-4)=a((-7)+8)^2-7$
