PLEASE HELP

1. A. y and 1.2y are like terms. c they both contain the same term (y) and can therefore be combined.

2. B. 12x+11 (you have to combine the like terms)

3. 15y+18-4
C. 15y+14 (you must distribute the 3 to inside the parentheses, so 3×5y and 3×6)

4. 9(9-3p) (you have to find a common factor between the terms, in this case 9, and you place it on the outside of the parentheses, while dividing that factor from those terms, which are placed in parentheses.

WILL MARK BRAINLIEST IF CORRECT!

Answer:

\lim_{x \to -\infty} f(x)= - \infty \\  \lim_{x \to \infty} f(x)= -\infty

Step-by-step explanation:

f(x)=-x^4-x^3+3x^2+1

The question wants you to determine the end behavior of this polynomial function.

In order to determine the end behavior of polynomial functions, you want to look at the polynomial in its general form. This means that the variables have powers that are in descending order.

Look at the leading term of the polynomial in general form. Here, the function f(x)=-x^4-x^3+3x^2+1 is in general form, so we can look at the first term (term with the highest power).

The leading term for this polynomial function is -x^4. The leading term has the highest power; therefore, its behavior will dominate the graph shape.

When graphed, this function will behave similarly to an upside down parabola.

Based on the leading term, we can see that the leading coefficient is -1 and the degree is 4.

Look to see if the degree is <u>even/odd</u>, and if the leading coefficient is <u>negative/positive</u>.

The degree of 4 is even, and the leading coefficient of -1 is negative.

When the degree is even and the LC is negative, the graph of the polynomial function falls to the left and falls to the right.

Therefore, if the end behavior falls to the left and falls to the right, that means that as x approaches negative infinity and positive infinity, the y-values will approach negative infinity and negative infinity on either side of the graph.

The answer is the rightmost option:

\lim_{x \to -\infty} f(x)= - \infty \\  \lim_{x \to \infty} f(x)= -\infty

kicyunya [14]
Almons:walnuts:rasins=1:2:3


x=pounds of walnuts
y=pounds of almonds
z=pounds or rasins
2x=y
3x=z
subsitute


12x+9y+5z=15
12x+9(2x)+5(3x)=15
12x+18x+15x=15
45x=15
divide by 45
x=1/3
so
1/3 pound of walnuts
2x=y
2(1/3)=y=2/3
2/3 pounds of almonds
3x=z
3(1/3)=z
1=z
1 pound of rasins




1/3 pound walnuts
2/3 pound almonds
1 pound rasins
