**Answer 1**

**Answer:**

The equation of a line is y = ax + b, where a is the slope and b is the y-intercept.

Since we have the y-intercept, all we need to do is find the slope. To find the slope, you need 2 coordinates.

The y-intercept is where the line crosses the y axis, so it is where x is 0. Since the y intercept is -2, that means the first coordinate is (0, -2)

The x-intercept is where the line crosses the x axis, so it is where y is 0. Since the x intercept is 4, that means the second coordinate is (4, 0)

Since we already have the y-intercept, all we do is put the slope in the equation: y = 1/2x - 2.

Two sisters, Crystal and Alexa, are going to a strange birthday party. Instead of birthday cake,

pairs of party guests are each served a large chewy fruit worm to share according to their ages.

Since the sisters are not the same age, they do not share their fruit worm equally.

Crystal is 12 years old and Alexa is 6 years old. Their chewy fruit worm has 18 segments.

According to their ages, Crystal gets 12 segments and Alexa gets 6 segments. The ratio of the

girls' shares of the worm, 12 to 6, is equivalent to the ratio of their ages, 12 to 6.

• According to the rule, how would the girls share a 9-segment chewy fruit worm?

Since Crystal's age is two times Alexa's age, Crystal gets twice as many segments as Alexa.

The ratio of Crystal's segments to Alexa's segments is 12 to 6 or 2 to 1.

. The ratio 2 to 1 is a unit rate. What do the numbers 2 and 1 mean for the sisters?

12 to 6

In this Problem you will explore situations that involve fractions and ratios.

An account with an initial deposit of 3,500 earns 7.25% annual interest, compounded continuously. How much will the account be worth after 30 years? Round to the nearest cent.

### Answers

Answer: $28,575.05

Step-by-step explanation:

Formula: FV = (1+r/n)^nt

FV = future value of the deposit

P = principal or amount of money deposited

r = annual interest rate (in decimal form)

n = number of times compounded per year

t = time in years.

3,500(1+7.25%)^30=28,575.05468

**Answer:**

blue point value is -10

**Step-by-step explanation:**

First lets find the difference between each point on the line,

The gap between 10 and 2 has 2 points

So 10 - 2 = 8 is the difference in value between point A(10) and point C(2), but we need to find difference between each point,

So 8/2 = 4 is the difference between each point from top to bottom.

There is 3 points after 2 to reach blue,

So 4 x 3 = 12, is the difference in value between point C(2) and point blue,

So, subtracting 12 from 2 will get us the value of blue, 2 - 12 = -10

Therefore the value of blue point is -10

### Answers

Answer:. sum of interior angles:

Heptagon: 900°

14gon 2160°

Step-by-step explanation: Divide 360 by the number of sides to get the measure of the average or regular central angle (same as an exterior angle)

360/7 = 51.43 360/14 = 25.7.

Subtract from 180 to find the interior angle.

180 - 51.43 = 128.57

180 - 25.7 = 154.3

Multiply the measure of the interior angle by the number of sides to find the sum of the interior angles.

128.57× 7 = 900

154.3 × 14 = 2160

L is the

length of one side of the pasture

Given

L = 2x³

Area of the pasture = (2x³)²

Area of the pasture =2x³•2x³

Area of the pasture = 4x^{3+3}

Area of the pasture = 4x^6

Which of the following is a counterexample for the hypothesis "All parallelograms are rectangles"?

### Answers

**Answer:**

The answer would be B

**Step-by-step explanation:**

A non-square rhombus. A non-square rhombus (also known as a rhombus) is different from a square with respect to its internal angles. Unlike a square, a non-square rhombus does not have all its internal angles equal to 90°. The number of lines of symmetry in a non-square rhombus is 2, whereas, a square has 4 lines of symmetry.

The required **counterexample **is **rhombus **for the given **hypothesis **"All **parallelograms **are **rectangles**" which is the correct **answer **would be **option **(**B**).

What is the hypothesis?

In statistics, hypothesis testing is the process by which an **analyst **tests an assumption about a population's parameter. Using sample **data, hypothesis **testing is performed to examine the plausibility of a theory.

A rhombus that isn't **square**. In terms of **internal angles**, a non-square rhombus (also known as a **rhombus**) differs from a square. A non-square rhombus, unlike a square, does not have all of its internal angles equal to 90°. A non-square rhombus has two lines of **symmetry**, whereas a square has four **lines **of symmetry.

Therefore, the required **counterexample **is **rhombus **for the given **hypothesis **"All **parallelograms **are **rectangles**"

A hospital employs a total of 77 nurses and doctors. The ration if nurses to doctors is 9:2. How many nurses are employed at the hospital? How many doctors are employed at the hospital?

### Answers

**Answer: 63 nurses and 14 doctors**

so you know the ratio is 9:2. that means for every 9 nurses there are 2 doctors. i didn't make an equation but i counted it.

if theres 9 (9***1**) nurses theres 2 (2***1**) doctors

if theres 18 (9***2**) nurses theres 4 (2***2**) doctors

if theres 27 (9***3**) nurses theres 6 (2***3**) doctors

you get the point so i multiplied **7** to 9 and **7** to 2, which means:

if theres 63 (9***7**) nurses theres 14 (2***7**) doctors

Can someone tell me the slope ?

### Answers

**Answer:**

slope = 4

**Step-by-step explanation:**

We can find the slope of a line when knowing 2 points by using the slope formula, [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of the first point, respectively. [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of the second point, respectively.

The two points we have are (2,8) and (0,0). So, in this case, [tex]x_1[/tex] = 2, [tex]y_1[/tex] = 8, [tex]x_2[/tex] = 0, and [tex]y_2[/tex] = 0. Let's substitute those values into the formula and solve to get the slope:

[tex]m =[/tex] [tex]\frac{0-8}{0-2}[/tex]

[tex]\frac{-8}{-2}[/tex]

[tex]4[/tex]

So, the slope is 4.

### Answers

**Answer:**

y = 3x + 11

**Step-by-step explanation:**

Substitute the information into the point-slope form equation.

Point-slope form: y - y₁ = m(x - x₁)

y - 2 = 3(x - (-3))

y - 2 = 3(x + 3)

y - 2 = 3x + 9

y = 3x + 11
