The **equation** that shows **Silas's** **age**, S, in terms of Mark's age is

S = (M - 6)/2.

Option D is the correct answer.

What is an expression?An **expression** is a way of writing a statement with more than two variables or numbers with **operations** such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

**Silas's** age = S

Mark's age = M

Hailey's age = H

Now,

H = 2S + 4

H = M - 2

This means,

2S + 4 = M - 2

2S = M - 2 - 4

2S = M - 6

S = (M - 6)/2

Thus,

**Silas's** age is (M - 6)/2.

If the cubic function P(x) includes the points (−4, 0), (0, 0), and (2, 0), which of the following represents this function?

**Answer:**

See below

**Step-by-step explanation:**

(-4,0) is the solution to x+4=0

(0,0) is the solution to x=0

(2,0) is the solution to x-2=0

Therefore, (x+4)(x-2)(x) = (x²-2x+4x-8)(x) = (x²+2x-8)(x) = x³+2x²-8x is the function that has the given zeroes

Howie wants to get a car loan with 4% simple interest rate. If the car costs $25,000, how much would Howie need to pay back at the end of one year, including the interest?

The **amount **Howie will pay back at the **end **of **one year** is $26000.00

The given parameters are:

[tex]P =25000[/tex] -- the **principal amount**

[tex]R = 4\%[/tex] -- the **interest rate**

[tex]T=1[/tex] --- the **duration**

The **amount **to pay back in this **duration **is then calculated using:

[tex]A = P(1 + RT)[/tex]

So, we have:

[tex]A = 25000(1 + 4\% \times 1)[/tex]

[tex]A = 25000(1 + 4\% )[/tex]

Express percentage as decimal

[tex]A = 25000(1 + 0.04)[/tex]

[tex]A = 25000(1 .04)\\[/tex]

Multiply

[tex]A = 26000[/tex]

**Step-by-step explanation:**

1. A boat is marked up 20% on the original price. The original price was $50. What is the sale price of the boat before sales tax?

$50(1+0.20) = **$60**

2. Fred buys a video game disk for $4. There was a discount of 20%. What is the sales price?

$4(1-0.2) = **$3.20**

3. A painting is on sale at 50% off. The sale price is $320. What was the original price?

X*(1-0.5) = $320

14. A triangle has vertices at A(4,2), B(-4,-2), and

origin using a scale factor of 172, what will the

coordinates for the new vertices be?

A A' (2.1). B' (-2,-1), and C (1.-2)

B. A (8.4), B (-8,-4). and C (4. - 8)

C. A' (1,2), B (-1,-2), and C (-2. - 1)

D. A (-2,-1), B' (-2,-1), and C° (-1,2)

**Answer:**

A

**Step-by-step explanation:**

Each coordinate of the triangle will have to dilate by 1/2 in order for the triangle to be fully dilated. Let's check each option to see which one has the correctly dilated points.

First, we'll look at A. A(4, 2) goes to A'(2, 1)... which is looking good so far! Half of 4 is 2, and half of 2 is 1, so the right dilation was applied. Next, let's check out B. B(-4, -2) goes to B'(-2, -1), which is still looking okay. Half of -4 is -2, and half of -2 is -1. Finally, we'll check the point C. If this one is correctly dilated, option A is the right option. C(2, -4) goes to C'(1, -2), and we can now be sure that option A is correct. Half of 2 is 1, and half of -4 is -2.

So, **option A** is the one to select. Hopefully that's helpful! :)

What is the vertical shift for the absolute value function below f(x) =9 |x+1|+2

Answer:

Slide UP 2

Step-by-step explanation:

In the equation,

f(x) = 9|x+1| + 2

There are three transformations of the parent function f(x)=|x| (this is the simplest form of this function, it's a v-shaped graph)

The 9 in front will vertically stretch the graph and make it look like a "skinny" v-shaped graph.

The +1 in close to the x inside the absolute value bars |x+1| will shift (slide) the graph to the left (it's the opposite of what you might think-- 'plus' shifts the graph left and 'minus' shifts the graph right)

The +2 at the end is the transformation you're looking for. It slides the graph as you would expect UP 2 units. If it was a minus it would shift the graph down instead.

if you roll a fair 6-sided die 9 times, what is the probability that at least 2 of the rolls come up as a 3 or a 4?

Using the **binomial distribution**, it is found that there is a **0.857 = 85.7% probability** that at least 2 of the rolls come up as a 3 or a 4.

For each die, there are only **two possible outcomes**, either a 3 or a 4 is rolled, or it is not. The result of a roll is **independent **of any other roll, hence, the *binomial distribution* is used to solve this question.

**Binomial **probability distribution

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The **parameters **are:

In this problem:

There areThe desired **probability **is:

[tex]P(X \geq 2) = 1 - P(X < 2)[/tex]

In which:

[tex]P(X < 2) = P(X = 0) + P(X = 1)[/tex]

Then

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{9,0}.(0.3333)^{0}.(0.6667)^{9} = 0.026[/tex]

[tex]P(X = 1) = C_{9,1}.(0.3333)^{1}.(0.6667)^{8} = 0.117[/tex]

Then:

[tex]P(X < 2) = P(X = 0) + P(X = 1) = 0.026 + 0.117 = 0.143[/tex]

[tex]P(X \geq 2) = 1 - P(X < 2) = 1 - 0.143 = 0.857[/tex]

**0.857 = 85.7% probability** that at least 2 of the rolls come up as a 3 or a 4.
