Here is my work for the problem. Hope this helps!
When you estimate, you round each number, the add.
We round them to
700+620, which is 1320
So our non estimated answer is 1323
But our estimated answer is 1320
By applying the definition of continuity and knowing piecewise functions, we know that the solution to this system of linear equations is c = 10 and d = -8.
<h3>How to make a piecewise function continuous</h3>
According to the <em>functional</em> theory, functions are continuous for a given interval if and only if the function has an only value for each element of the interval. In the case of the <em>piecewise</em> function, we must observe these two conditions:
2 · x = c · x² + d, for x = 1 (1)
4 · x³ = c · x² + d, for x = 2 (2)
Then, we have the following system of linear equations:
c + d = 2 (1b)
4 · c + d = 32 (2b)
The solution to this system of linear equations is c = 10 and d = -8.

-6
You would divide -4.3 on both sides. Since -4.3 divided by itself equals 1 the g will be isolated. So the answer would be -6 because 25.8 divided by -4.3 is -6.
White paint = 2/3 * 17 = 11.33 liters , 11.33*2.10 = $23.8
blue paint = 1/3 * 17 = 5.66 liters, 5.66*1.50 = $8.5
Total cost = 23.8+8.5 = 32.30 euros
