Answer:
3.5
Step-by-step explanation:
you want to add all of the balls together and then divide by 4 because that's how many color balls there are

To find the gradient of the tangent, we must first differentiate the function.

The gradient at x = 0 is given by evaluating f'(0).

The derivative of the function at this point is negative, which tells us <em>the function is decreasing at that point</em>.
The tangent to the line is a straight line, so we will have a linear equation of the form y = mx + c. We know the gradient, m, is equal to -1, so

Now we need to substitute a point on the tangent into this equation to find c. We know a point when x = 0 lies on here. To find the y-coordinate of this point we need to evaluate f(0).

So the point (0, -1) lies on the tangent. Substituting into the tangent equation:
<u>Answer:</u>
Yes, I believe so.
<u>Step-by-step explanation:</u>
When you look at this equation on a graphing table, it is a straight line that goes directly through the 0,0 cords.
I hope this helped!
If it's wrong I'm very sorry!
Answer:
6x - 3
Step-by-step explanation:
2(x-3) + 4x + 3
= 2x - 6 + 4x + 3 (Multiply out)
= 2x + 4x - 6 + 3 (Rearrange)
= 6x - 3
Answer:
4
Step-by-step explanation:
20×25 = 500
20 guest
25 dollars per guest
75s+200= 500
75s = 300
S = 4
