Answer:
9x⁻² is not a polynomial
Step-by-step explanation:
A polynomial function is a function that involves non-negative integer powers of x such as a quadratic, cubic etc.
A polynomial is a function written in the form of ;
f{x} =aₙxⁿ+aₙ₋₁xⁿ⁻¹+-------+a₂x²+a₁x+a₀
The degree of a polynomial is the highest power of x in the expression
9x⁻² ----in this case, the power is negative thus this is not a polynomial.
Answer and Step-by-step explanation:
[] means to take the absolute version of the number. That means if the number is negative or positive, the outcome is always positive.

Answer:
(-4,-2)
x=-4
y=-2
Step-by-step explanation:
-3x-4y=20
3(x-10y=16)=3x-30y=48
The reason I multiplied 3 to the second equation is for when we add the equations together the x will cancel out.
-3x-4y=20
+ <u>3x-30y=48</u>
-34y=68
Divide -34 from both sides.
y=-2
To find x you need to plug in -2 for y into one of the equations.
x-10y=16
x-10(-2)=16
Remember a negative times a negative equals a positive.
x+20=16
Subtract 20 from both sides.
x=-4
Hope this helps!
If not, I am sorry.
Answer:
I am pretty sure it's A and I am very sorry if I'm wrong
Step-by-step explanation:
The way I would think about this question is this: because Jordan only wants to work a maximum of 40 hours, he can work 40 hours or less. Which is described as an equation in the top equation of letter A. And because he also wants to make $250 or more, the bottom equation in A would work as well.
I hope that makes sense! Please ask me in the comments if you want more explanation on it
