Answer:
D
Step-by-step explanation:
Domain & Range is just x and y.
the function includes x values between & including -2 and 2, while y includes 3, and -3
The expression which can be used to determine the algebraic sum of the given polynomials as in the task content is; -11x² +4x +14.
<h3>Which expression can be used to find the sum of the given polynomials?</h3>
It follows from the task content that the polynomials whose sum are to be determined are; (9 - 3x2) + (-8x2 + 4x + 5).
Hence, the sum can be evaluated as follows;
= 9 - 3x² + -8x² + 4x + 5
= -11x² +4x +14.
Consequently, the required expression is; -11x² +4x +14.

Answer:
2 hours
Step-by-step explanation:
first tap= 3hours
therefore work done is = 1/3
second tap= 6hours
therefore work done = 1/6
so, 1/3+ 1/6
=2/6 + 1/6
=3/6
=1/2
=2/1 hours
=2 hours
Answer:
KM = 4 units
Step-by-step explanation:
mathematically;
since l is on line segment KM
KM = KL + LM
substituting values;
5x + 4 = 5x + 1 + 3x + 3
5x + 4 = 8x + 4
8x-5x = 4-4
3x = 0
x = 0
KM = 5x + 4 = 5(0) + 4 = 4 units
Well, let's first square 3.5x10^4 which is 1,225,000,000
Scientific notation is when you put a decimal place after the first digit and then say the answer is that multiplied by 10 to a power. This power is the number of digits that come after the first. In this case, the power should be 9 (if you count the 225 and all the 0's, you'll count 9 numbers).
Thus the answer is 1.225x10^9
