Answer:
I am assuming that you are talking about problem 2. so I will answer that.
Step-by-step explanation:
-2x + 6 ≥ 3x - 34
+2x +2x
6 ≥ 5x - 34
+34 + 34
40 ≥ 5x
÷5 ÷5
8 ≥ x
So, x can be anything equal to or less than 8.
5,10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85,90,95,100 etc.
Answer:
a)12 b)12 c)36
Step-by-step explanation:
a)find least common multiple. the number of marbles is that number * n (where n is an integer)
b) the least common multiple. it is 4*3=...
c)12*3 =?
then just divide by 2,3,4 to get answer
We know that the parabola opens downwards because it has a negative leading coefficient.

Why the parabola opens downwards?</h3>
For any polynomial, the leading coefficient is the coefficient in the term where is the large exponent of the polynomial.
The sign of that coefficient will determine the end behavior of the graph of the polynomial.
For the case of the parabola, a positive leading coefficient means that the parabola opens upwards, while a negative leading coefficient will mean that the parabola opens downwards.
Now, if you look at our parabola:
g(x) = -(x + 1)^2 - 3
You can see that there is a negative sign, thus when we expand the parenthesis, we will end up with a negative leading coefficient:
g(x) = -x^2 - 2x + 1 - 3 = -x^2 -2x - 2
So we know that the parabola opens downwards.
