<h3>Answer: Choice C)   x^4 - 2</h3>

Explanation:

If the exponent is negative, then that means we apply the reciprocal. So something like x^(-2) becomes 1/(x^2). A polynomial cannot have a variable in the denominator like this. So we can rule out choices A, B, and D. Choice C is the only thing left. It is a polynomial because the exponent is a positive whole number.

Solve the following system.
rusak2 [61]
Y = x + 3 . . . (1)
4x + y = 18 . . . (2)

Putting (1) into (2) gives
4x + x + 3 = 18
5x = 18 - 3 = 15
x = 15/5 = 3
x = 3
y = x + 3 = 3 + 3 = 6

Solution = (3, 6)

Answer:

Step-by-step explanation:

Y = x² - 2x + 5

x = -2

y = -2² -2(-2) + 5

y = 4 + 4 + 5 = 13

x = -1

y = -1² -2(-1) + 5

y = 1 + 2 + 5 = 8

x = 1

y = 1² -2(1) + 5

y = 1 - 2 + 5 = 4

x = 3

y = 3² -2(3) + 5

y = 9 - 6 + 5 = 8

x = 6

y = 6² -2(6) + 5

y = 36 - 12 + 5 = 29
