Answer:
1, because you can subtract both equations to eliminate y , and you will be left with only x.
Step-by-step explanation:
Answer: 5/x3-1/x2+8/x-40 is not polynomial. The rest are polynomial.
Step-by-step explanation:
Polynomials cannot have a number divided by a variable so 5/x3-1/x2+8/x-40 can't be a polynomial.
We are given that there are a total of 78 students. If we set the following variables:
Then, the sum of all of these must be 78, that is:
Since there are 15 in chemistry and physics and 47 in chemistry, we may replace that into the equation and we get:
Simplifying:
Now we solve for P by subtracting 62 on both sides:
Therefore, there are 16 students in physics
Answer:
(c) For p = 15, leaves a remainder of -2 when divided by (x-3).
Step-by-step explanation:
Here, The dividend expression is = E(x)
The Divisor = (x-3)
Remainder = -2
Now, by <u>REMAINDER THEOREM</u>:
Dividend = (Divisor x Quotient) + Remainder
If ( x -3 ) divides the given polynomial with a remainder -2.
⇒ x = 3 is a solution of given polynomial E(x) - (-2) =
= S(x)
Now, S(3) = 0
⇒
or, p =1 5
Hence, for p = 15, leaves a remainder of -2 when divided by (x-3).
Answer: 60 divided by 4 = 15
