Because X and Y are directly proportional, this means what ever happens to one, the same thing happens to the other one.
The correct answer would be: it depends on the starting value of x.
Answer:
3
Step-by-step explanation:
$1.75 (ice cream) + $0.35 (topping) * x (some toppings) = $2.80, so I can rewrite it like that: 1.75+0.35x=2.80
1) Move the constant to the right side and change its sign: 0.35x=2.8-1.75
2) Substract the numbers: 0.35x=1.05
3) Divide the both sides of the equation by 0.35
4) x=3
Well if your equation is 9=-2/3x-y, you’ll have to make it into y=Mx+b form first so subtract 9 from both sides and add y from both sides. your equation should be y=-2/3x-9. therefore you’re answer is 4.

The polynomials can´t contain:
-Variables in the exponents of the terms.
-Variables in the denominator.
- Negative exponents.
-Fractionals exponents.
-The variables cant be as radicals.
Therefore:
a) It is a polynomial (The variable is under a radical)
b) It is not a polynomial.
c) It is a polynomial.
d) It is not a polynomial. (It has a variable in the denominator).
e) It is a polynomial.
f) It is not a polynomial. <span> (It has a </span><span>variable in the denominator).</span>
