Step-by-step explanation:

Step 1: Define

3x - y = 18

y = 27

Step 2: Solve for x

Substitute in y:                     3x - 27 = 18Isolate x term:                      3x = 45Isolate x:                               x = 15

Answer:

15

Step-by-step explanation:

3x - y = 18

Insert the value of y in the equation.

3x - 27 = 18

Shift -27 to the other side of the equation.

3x = 18 + 27

3x = 45

x = 45 ÷ 3

x = 15

So please check if your options and the equation are correct.

Do the rates charged for life insurance remain the same throughout your life? Give some reasons why they may fluctuate or why they may remain the same.

Answers

Answer:

Yes

Step-by-step explanation:

Yes, when you purchase a life insurance policy you will be charged a certain rate but this can change if there are sudden changes in your health or as you get older. In some cases, you may purchase an insurance policy for a certain amount of years in which the rate is guaranteed to remain the same during that time. This type of policy's rate depends on the period of time you choose to be insured but once the time period is over the rate can increase a lot depending on your age and health at that time.

for the equation 2(4x+10)=8x+k what value of k will create infineltly many solutions please help

Answers

Answer:

The value of k = 20 for equation 2(4x+10)=8x+k to have infinitely many solutions.

Step-by-step explanation:

Given the expression

[tex]2(4x+10)=8x+k[/tex]

solving

[tex]2(4x+10)=8x+k[/tex]

[tex]8x+20 = 8x+k[/tex]

We know that the equations with infinitely many solutions have the same expressions on both sides

It means the value of k can be determined by further simplifying such as

[tex]8x+20 = 8x+k[/tex]

8x+20-8x = k

20 = k

Therefore, the value of k = 20 for equation 2(4x+10)=8x+k to have infinitely many solutions.

VERIFICATION:

Given

[tex]2(4x+10)=8x+k[/tex]

[tex]8x+20 = 8x+k[/tex]

Put k = 20 in the equation

[tex]8x+20 = 8x+20[/tex]

[tex]8x+20 - 8x+20 = 0[/tex]

[tex]0 = 0[/tex]

equations with infinitely many solutions have the same expressions on both sides.

This means the statement is always true.

Consider the polynomial function g(x)=10x^9-50x^6-500x^2
What is the end behavior of the graph of g?

Answers

Answer:

It falls to the left and rises to the right.

Step-by-step explanation:

The polynomial function is given as;

g(x) =10x^(9) - 50x^(6) - 500x²

In this polynomial, the leading coefficient is 10. This is positive and also an even number and thus it means the graph will rise to the right.

Also, the degree of the polynomial is 9 since that's the highest degree of x. This degree is odd and it means the graph will point in the opposite direction to that of the leading coefficient. Thus, we can say it falls to the left.

So in summary, the end behavior of the graph of g is that it falls to the left and rises to the right.

The end behavior of the polynomial is:

When x ⇒ ∞, g(x) ⇒ ∞When x ⇒ -∞, g(x) ⇒ -∞What is the end behavior of the graph of g(x)?

The first thing you need to notice is that the degree of the polynomial is odd. This means that the function will have two opposite end behaviors.

Also, the leading coefficient is positive (is 10). So, when x tends to positive infinity, the end behavior of the function will tend to positive infinity.

When x tends to negative infinity, because the exponent is odd, the outcome will also be negative. Then here the end behavior of the function will tend to negative infinity.

Concluding, we can write:

When x ⇒ ∞, g(x) ⇒ ∞When x ⇒ -∞, g(x) ⇒ -∞

4 (1a + b – 6)

Answers

Answer:

4a + 4b - 24

Step-by-step explanation:

You first start off by giving (multiplying) 4 to everything that's in the parenthesis.

Second you multiply:

4 x 1a = 4a

4 x b = 4b (also remember that a variable by its self is just 1)

4 x -6 = -24

Lastly you put it together:

4a + 4b - 24

For the -24 you can either do it the way I did or this way -> (-24) but teachers will look mostly for -24 way. But use whichever one is easier for you :)
