Write an equation in slope-intercept form for the line with slope 7 and y-intercept -8.

Answers

Answer:

y = 7x - 8

Step-by-step explanation:

The equation of a line in slope-intercept form is: y = mx + b, where m is the slope and b is the y-intercept.

The problem already gives us both of these values:

m = 7

b = -8

All we have to do is plug them in:

y = mx + b

y = 7x + -8

y = 7x - 8

Thus, the answer is y = 7x - 8.

A group of 5 friends went out to dinner. The total bill including the tax and tip came to $83.95. If they split the bill evenly, how much money does each person owe?

Mary is going to have an outdoor party in 10 days. She wants to have her backyard pond covered in water lilies before the party, so she goes to the nursery to buy some water lilies. Mary gives the clerk the dimensions of her pond, and the clerk, knowing the growth rate of the water lilies that he stocks, calculates that if she purchases a single water lily, it will produce a population of ten thousand lilies that will completely cover the surface of the pond in 20 days. Mary reasons that if she buys two water lilies instead of one, she can meet her goal of having the pond surface covered in 10 days. Is there anything wrong with Mary's reasoning? How many water lilies will Mary need to buy to meet her goal?

Answers

Answer:

a. There is nothing wrong with Mary's reasoning b. 2 water lilies.

Step-by-step explanation:

a. This is because, she reasons that if she doubles the amount of water lilies she buys, it would take half the time it takes to produce 10,000 lilies. So, there is nothing wrong with Mary's reasoning.

b. Since it takes 1 water lily to produce 10000 lilies in 20 days, 1 water lily will produce x lilies in 10 days.

So, x = 10000 × 10/20 = 5000 lilies

So, 1 water lily produces 5000 lilies in 10 days.

So, x water lilies will produces 10000 lilies in 10 days.

So x = 10000 × 1/5000 = 2 water lilies

So, 2 water lilies will produce 10000 lilies in 10 days.

So, Mary needs 2 water lilies so she can meet her goal of having the pond surface covered in 10 days.

To find the area of a rectangle, multiply the length and the width.
The length of a rectangle is (X - 6) and the width of the rectangle is (x - 10). What is the area of the rectangle?

Answers

Answer:

Step-by-step explanation:

area = length * width

area = (x - 6) (x - 10)

area = x (x - 10) - 6 (x - 10)

area = x^2 -10x -6x -10

area = x^2 -16x -10

The dimensions of a rectangular prism are 24 ft x 20 ft x 15 ft. What is the surface area

Answers

Answer:

2280 ft^2

Step-by-step explanation:

A rectangular prism has 6 faces. Each pair of opposite faces is congruent.

surface area = 2LW + 2LH + 2WH

surface area = 2(24 ft)(20 ft) + 2(24 ft)(15 ft) + 2(20 ft)(15 ft)

surface area = 960 ft^2 + 720 ft^2 + 600 ft^2

surface area = 2280 ft^2

If a gun fires 88 rounds per minute, how many rounds would it fire in 45 minutes?

Answers

Answer:

3960

Step-by-step explanation:

1minute = 88rounds

45minutes = xrounds

1/45 = 88/x

45(88)= 3960

3960/1 = 3960

x = 3960

The gun fires 3960 rounds in 45 minutes.

What is the proportion?

A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.

Let x rounds would it fire in 45 minutes

As per the situation, we can write the proportion would be as:

1 minute : 88 rounds = 45minutes : x rounds

⇒ 1/88 = 45/x

Apply the cross-multiplication, and we get

⇒ x = 45(88)

⇒ x = 3960

This means a gun fires 3960 rounds in 45 minutes.

Let x be the number of readers of the newspaper

It can be written as:

A: No. The graph is not reflected across x-axis. For this to happen, there should be a negative sign: g(x) = -x, for example

B: No, the graph doesn't translate. The graph only translates if there is: g(x) = a(x-c)+b, where b defines the vertical translation, and c the horizontal one.

C: No. This would happen for g(x)=x/2, for example.

How do you know whether two quantities x and y are proportional?

1. Every ratio yx for related pairs of x and y is equivalent.
2. Every sum x + y is the same for related pairs of x and y.
3. Every x term is a multiple of the previous term.
4. Every difference x – y is the same for related pairs of x and y please help me​

Answers

Answer:

The correct answer is:

1. Every ratio yx for related pairs of x and y is equivalent.

Step-by-step explanation:

Proportion is defined as the relationship between two quantities. When one quantity changes the other is also changes.

For two quantities y and x when we say that both are proportional then t can be written as:

y∝x

Removing the proportionality symbol introduces a constant which is the ratio of y and x.

[tex]\frac{y}{x} = k[/tex]

This ratio of y and x, i.e. k is equivalent for all related pairs of x and y.

Hence,

The correct answer is:

1. Every ratio yx for related pairs of x and y is equivalent.

What Is a Random Variable?

A random variable is a variable whose value is unknown or a function that assigns values to each of an experiment's outcomes. Random variables are often designated by letters and can be classified as discrete, which are variables that have specific values, or continuous, which are variables that can have any values within a continuous range.

Given here: The distribution of X is geometric and has an expected value of approximately 2.86. And  35 percent of the customers order the daily special each day. Thus clearly the correct and precise interpretation of the statement is  Over many days,  It takes about 2.86 orders, on average, to be placed until the first daily special is ordered.

Hence, Option C is the correct answer.
