Answer:
it is C. i think but idk sry:(
Step-by-step explanation:
Perhaps you meant <span>(a^3+14a^2+33a-20) / (a+4), for division by (a+4).
Do you know synthetic division? If so, that'd be a great way to accomplish this division. Assume that (a+4) is a factor of </span>a^3+14a^2+33a-20; then assume that -4 is the corresponding root of a^3+14a^2+33a-20.
Perform synth. div. If there is no remainder, then you'll know that (a+4) is a factor and will also have the quoitient.
-4 / 1 14 33 -20
___ -4_-40 28___________
1 10 -7 8
Here the remainder is not zero; it's 8. However, we now know that the quotient is 1a^2 + 10a - 7 with a remainder of 8.
35.0: the answer to the question
Answer:
it is a linear function
Step-by-step explanation:
Using a system of equations, the prices are given as follows:
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For this problem, the variables are given as follows:
- Variable x: Cost of a reference book.
- Variable y: Cost of an exercise book.
3 reference and 2 exercise cost RM63, hence:
3x + 2y = 63.
5 reference and 3 exercise cost RM102, hence:
5x + 3y = 102.
Multiplying the first equation by 3 and the second by -2, we have that:
Adding them:
-x = -15 -> x = 15.
Hence:
3(15) + 2y = 63
2y = 18.
y = 9.
Hence the costs are:
