Answer:

X =5y

Step-by-step explanation:

1 Subtract yy from both sides.

6x=4x+11y-y

6x=4x+11y−y

2 Simplify 4x+11y-y4x+11y−y to 4x+10y4x+10y.

6x=4x+10y

3 Subtract 4x4x from both sides.

6x-4x=10y

6x−4x=10y

4 Simplify 6x-4x6x−4x to 2x2x.

2x=10y

5 Divide both sides by 22.

x=\frac{10y}{2}

10y

6 Simplify \frac{10y}{2}

10y

to 5y5y.

In the 1st generation, there are 8 raccoons in a forest.

Talja [164]

Answer:

$a(n)=8.3^{n-1}$

Choice D is correct

Step-by-step explanation:

The sequence representing the number of raccoons;

8, 24, 72

is simply but a geometric sequence with first term 8 and common ratio 3.

The formula for the n-th term of a geometric sequence with first term x and common ration r is;

$a(n)=xr^{n-1}$

In the given case, x = 8 and r = 3

We substitute these values in the above formula;

$a(n)=8.3^{n-1}$

Choose the table that represents g(x) = −2⋅f(x) when f(x) = x + 4.

grigory [225]

Answer: THIRD OPTION.

Step-by-step explanation:

Since $g(x) = -2f(x)$ , then $g(x)$ is:

$g(x)=-2( x + 4)\\\\g(x)=-2x-8$

In order to find which table represents $g(x) = -2f(x)$ when $f(x) = x + 4$ , you can follow these steps:

1. Substitute $x=1$ into the function $g(x)=-2x-8$ :

$g(1)=-2(1)-8\\\\g(1)=-10$

2. Substitute $x=2$ into the function $g(x)=-2x-8$ :

$g(2)=-2(2)-8\\\\g(2)=-12$

3. Substitute $x=3$ into the function $g(x)=-2x-8$ :

$g(3)=-2(3)-8\\\\g(3)=-14$

Notice that those ouput values (for $x=1,\ x=2$ and $x=3$ ) matches with the table provided in the third option. That table represents $g(x) = -2f(x)$ when $f(x) = x + 4$ :

Find an explicit rule for the nth term of the sequence.

Paladinen [302]

Find the difference between the existing terms:

-8 / -4 = 2

-16/-8 = 2

This means the next term is the previous term multiplied by 2:

The first term is given as -4

You would start with the first term ( -4) then multiply it by the difference of terms ( 2) raised to the nth term (n) minus 1.

An = -4 * 2^n-1

The answer is A
