Answer:

See attached image

Step-by-step explanation:

In order to graph, find about three different points that belong to the line, and join them with a straight line.

The points I suggest are using easy values of "x" that will make the calculation of the y-value simple. For example the x-values: 0, 5, -5

When x = 0 , y becomes: y = -(2/5) (0) + 5 = 5

When x = 5,  y becomes : y = -(2/5) (5) + 5 = - 2 + 5 = 3

When x = -5,  y becomes: y = -(2/5) (-5) + 5 = 2 + 5 = 7

Then plot the points (0, 5), (5, 3) and (-5, 7) on the plane, and join them with a line as shown in the attached image.

Answer:  The slope is 2/3

Step-by-step explanation:

The difference in the rise (y-values) 2,  divided by the difference in the run (x-values) 3,  is 2/3.

You can see this by looking at the places where the graphed line crosses the grid, and counting the squares in each direction between those points, or you can use the formula (y - y₁) ÷ (x - x₁)  

Using the values of coordinates (3,1) and (0, -1)

1 -(-1) ÷ 3 - 0

2 ÷ 3

2/3

The slope of the given line is 2/3.

From the given figure, the coordinates of the points on line are (3, 1) and (-3, -3).

The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of that line.

The slope of a line is m=(y2-y1)/(x2-x1)

Using the coordinates (x1, y1) = (3, 1) and (x2, (y2) = (-3, -3)

Slope(m) = (-3-1)/(-3-3)

= -4/(-6)

= 2/3

Therefore, the slope of the given line is 2/3.

The amount of money invested in growth fund was $2000, $2000 was invested in income fund and $1000 was invested in money market fund.

An equation is an expression that shows the relationship between two or more numbers and variables.

A variable can either be independent or dependent. A dependent variable depends on other variable while an independent variable does not depend on other variable.

Let x represent the money invested in growth fund, y represent that of income fund and z represent that of money market fund.

$5000 was invested, hence:

x + y + z = 5000     (1)

Also:

0.12x + 0.08y + 0.05z = 5450 - 5000       (2)

Your teacher invested twice as much in the income fund as in the money market fund:

To divide 30 into five parts such that the first and last parts are in the ratio of 2:3, we can follow these steps:

1. Determine the ratio between the first and last parts. In this case, it is 2:3.

2. Add the ratio values together to find the total number of parts: 2 + 3 = 5.

3. Divide the total value (30) by the total number of parts (5) to find the value of each part: 30 / 5 = 6.

4. Multiply the value of each part by the respective ratio values to obtain the individual parts:

- First part: 2 * 6 = 12

- Second part: 6

- Third part: 6

- Fourth part: 6

- Last part: 3 * 6 = 18

Therefore, the five parts of 30, with the first and last parts in the ratio of 2:3, are 12, 6, 6, 6, and 18.

Answer:

Angle 1 = 99

Angle 2=81

Angle 3=99

Angle 4=81

Step-by-step explanation:

Angle one is given with this we can conclude angle 3 as they are vertical of each other.

Angle two can be seen as the sum of Angles 1 and 2 equal 180 as angle 1 is 99 we may assume angle two is 81.

Angle four is the vertical of angle two so it is 81 as well.

The total amount that Portfolio 2 earns is approximately $567.75.

To calculate the earnings for Portfolio 2, we need to calculate the return on each investment and then sum them up.

Return on Savings Account:

= $1,450 * 2.80%

= $40.60

Return on Government Bond:

= $2,200 * (-1.55%)

= -$34.10

Return on Preferred Stock:

= $3,700 * 11.70%

= $432.90

Return on Common Stock:

= $1,500 * 8.49%

= $127.35

Total earnings for Portfolio 2 is:

= $40.60 + (-$34.10) + $432.90 + $127.35

= $567.75.

d. The result is 6.

a. -15 × (-3 + 5) - 15 + ?(-3)

Let's simplify the expression step by step:

-15 × (-3 + 5) - 15 + ?(-3)

First, we can simplify the expression within the parentheses:

-15 × 2 - 15 + ?(-3)

Next, we perform the multiplication and addition:

-30 - 15 + ?(-3)

Now, let's address the "?(-3)" part. Since we don't have a specific value for the missing factor, we'll leave it as it is for now.

-30 - 15 + ?(-3)

Finally, we can simplify the expression by performing the subtraction:

The final result is -45 + ?(-3).

b. √(-125 - 5) × 3²

Let's simplify this expression step by step:

√(-125 - 5) × 3²

First, we evaluate the expression within the square root:

√(-130) × 3²

Since we have a negative value inside the square root, this expression is not defined in the real number system. If you're working with complex numbers, we can proceed by evaluating the square root of -130.

c. (-5) - (-8) - (-7)

Let's simplify this expression step by step:

(-5) - (-8) - (-7)

To simplify double negatives, we can rewrite the expression as addition:

589.43 m is the approximate length of AB from the given triangle

The given diagram is a triangle. From the given triangle, the equivalent expression that will be used is given as:

Substitute the given parameters

482² = 358² + AB² - 2(358)(AB) cos 54.8

482² - 358² =  AB² - 716(AB) cos 54.8

Answer:

[tex] y = 8x + 16 [/tex]

[tex] x = 12 [/tex]

Step-by-step explanation:

Given two points on the line (0, 16) and (3, 40), an equation for the line can be written using the slope-intercept line equation which takes the format [tex] y = mx + b [/tex].

Where,

[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

b = y-intercept or the point at which the line cuts the y-axis.

Let's find slope (m) using the slope formula:

Let,

[tex] (0, 16) = (x_1, y_1) [/tex]

[tex] (3, 40) = (x_2, y_2) [/tex]

[tex] slope (m) = \frac{40 - 16}{3 - 0} [/tex]

[tex] slope (m) = \frac{24}{3} [/tex]

[tex] slope (m) = 8 [/tex]

Find b. Substitute the values of x = 0, y = 16, and m = 8 in the slope-intercept formula to find b.

[tex] y = mx + b [/tex]

[tex] 16 = 8(0) + b [/tex]

[tex] 16 = 0 + b [/tex]

[tex] 16 = b [/tex]

[tex] b = 16 [/tex]

Plug in the values of m and b into the slope-intercept formula to get the equation of the line.

[tex] y = mx + b [/tex]

[tex] y = 8x + 16 [/tex]

Let's use the equation to find x when y = 112.

[tex] y = 8x + 16 [/tex]

Substitute y = 112 in the equation

[tex] 112 = 8x + 16 [/tex]

[tex] 112 - 16 = 8x [/tex]

[tex] 96 = 8x [/tex]

Divide both sides by 8

[tex] 12 = x [/tex]

[tex] x = 12 [/tex]

The Probability that a randomly selected senior is both in the band and on the honor roll is 8/25.

To find the probability that a randomly selected senior is both in the band and on the honor roll, we need to divide the number of seniors who are in both categories by the total number of seniors.

Given:

Total number of seniors = 200

Number of seniors in the band = 32

Number of seniors in the band or on the honor roll = 64

Let's calculate the probability using these values:

Probability = Number of seniors in both categories / Total number of seniors

Probability = 64 / 200

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 8:

Probability = (64 ÷ 8) / (200 ÷ 8)

Probability = 8 / 25

Therefore, the probability that a randomly selected senior is both in the band and on the honor roll is 8/25.

53 years for the Population of the United States to reach 300 million people according to this model.

The recursive formula of the population of the United States is given by ao = an1.015a - 1

Let's solve this to get a formula that is not recursive.a0 = a0 givena1 = 1.015a0 - 1a2 = 1.015a1 - 1 = 1.015 (1.015a0 - 1) - 1 = 1.0152 a0 - 1.015 - 1a3 = 1.015a2 - 1 = 1.015(1.015²a0 - 1.015 - 1) - 1 = 1.015³ a0 - 1.015² - 1.015 - 1a4 = 1.015a3 - 1 = 1.015(1.015³a0 - 1.015² - 1.015 - 1) - 1 = 1.015⁴ a0 - 1.015³ - 1.015² - 1.015 - 1an = 1.015na0 - 1.015n-1 - 1.015n-2 - ... - 1.015 - 1We can rewrite this asan = a0(1.015)

where a0 is the population of the United States in 1910 (92.2 million people) .

Now, we need to write an exponential function to find the population of the United States as a function of time in years since 1910.P(t) = 92.2(1.015)

To find the number of years it takes for the population to reach 300 million people, we need to solve the equation92.2(1.015)t = 300

Dividing both sides by 92.2, we get1.015t = 3.2596

Taking the natural logarithm of both sides, we get ln(1.015) = ln(3.2596)t = ln(3.2596)/ln(1.015) ≈ 53.2

Therefore,  approximately 53 years for the population of the United States to reach 300 million people according to this model.
