What is the solution to the equation x − 15 = − 5?

75

20

− 20

− 75

Answer:

36

Step-by-step explanation:

[tex]2(2x - 5) = 2 x+ {2}^{3} \\ 4x - 10 = 2 x + {2}^{3} \\ 4x = 2x + 8 + 10 \\ 4x = 2x + 18 \\ 4x - 2x = 18 \\ 2x = 18 \\ x = \frac{18}{2} \\ x = 9 \\ \\ 4x = 4 \times 9 = 36[/tex]

Answer:

1. Median is 79 (in)

(78+80/2 => gives halfway point)

2. 7 (in)

(IQR is UQ - LQ => that is 82 - 75)

3. LQ is 75 (in)

4. Maximum height is 84 (in)

(the largest value or the tallest you could be)

Answer:

 1. $7.60  2. $3.70     3. $7.20    4. $9.20

Step-by-step explanation:

Using the given equation, it is found that it lands on the ground after 0.875 seconds.

It is given by:

[tex]h(t) = -16t^2 + vt + h[/tex]

In which:

In this problem, considering that the projectile jumps straight into the air with an initial vertical velocity of 14 ft/s, the parameters are v = 14 and h = 0, hence:

[tex]h(t) = -16t^2 + 14t[/tex]

It lands on the ground when h(t) = 0, hence:

[tex]-16t^2 + 14t = 0[/tex]

[tex]t(-16t + 14) = 0[/tex]

Then:

[tex]16t = 14[/tex]

[tex]t = \frac{14}{16}[/tex]

[tex]t = 0.875[/tex]

It lands on the ground after 0.875 seconds.

First month's profit of the company = $2,400.

After the first month, the profit is modeled by the function

J(t) = 2.5t + 1,250, t is the number of months after the first month the shop opened.

Now, P(t) describes the total profit earned by the company.

So, P(t) = (Profit earned from first month) + (Profit earned from remaining 11 months of the year)

= 2400 + (2.5t + 1250)

= 2.5t + 3650

Hence, total profit earned for the year = 2.5t + 3650.

Step-by-step explanation:

The graph that represents the equation y = -1/2x -3 is B

A graph is a series of points, discrete or continuous, forming a curve or a straight line, each of which represents a value of a given function.

Graphs could be positive, or negative.

When the increase in y results to an increase, in x then the graph is said to be positive graph while and increase in y leads to a decrease in x is called negative graph.

From the equation, y = -x/2 -3

If x = 0, then the y-intercept is  -3 which is below the x -axis.

Also, if x = 2, y will be -4, if x = 4, y = -5

These shows that as x increases y- decrease, making it a negative graph which slopes from left to right passing through the y-axis at x = -3 which is graph B

In conclusion the graph that represents the given equation is B

Answer:

2/15

Step-by-step explanation:

slow heart rate and blue eyes (2) over total (15)

2/15 doesn't simplify

Answer:

13/100 is my final answer

Step-by-step explanation:

First, in order to get blue eyes, you need to be part of 40% thats not much but not little either. Then in order to get A fast heart rate out of that, you need to be part of the 26% out of 40% and that leaves you with 13 to 14 %.

I say 13 to 14 because both the 13 and 26 % came from a decimal that went on forever but due to rounding it can be 27 gets fast heart rate with 13 percent gets slow heart rate and blue eyes or 14 gets it and 26 gets faster

Expression has numbers, variables, and mathematical operations. The expression 5(2n+1) is equivalent to 10n+5.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

As the expression is given to us, therefore, if we expand the expression it can be written as,

[tex]5(2n+1)\\\\=(5 \times 2n)+(5 \times 1)\\\\=10n+5[/tex]

Hence, the expression 5(2n+1) is equivalent to 10n+5.

Answer:

b 1.383

Step-by-step explanation:

it is a positive number

Answer:

Slope is undefined

Step-by-step explanation:

To find the slope, subtract the y's and put that on top of a fraction. Then subtract the x's and put that on the bottom of the fraction.

This works all the time for any two points.

Here, though, we find the top

4 - -6

= 4 + 6

= 10

10 would go on top.

But then, on the bottom we get

-8 - -8

= 0

We get zero. As you know, you CANNOT have zero on the bottom of a fraction.

For the slope calculation we get 10/0

The slope is undefined.

Also, if you graph these two points, it's a verticsl line. Vertical lines (up and down) have an undefined slope.

Answer:

B) 243 km^3

Step-by-step explanation:

The formula for volume is Length x width x height, so we must find those values. By looking at the shape, the length is 9 km, width is 9 km, and height is 3 km, and after substituting these values in the equation, we get 9 km x 9 km x 3 km. When multiplied, it equals to 243 km^3, so the answer for the volume of the solid is B) 243 km^3.

Answer:

The answer is 1.2

Step-by-step explanation:

It takes Rita 22.75 on average, and it take Erika 21.55 to walk the mile on average.

21.55 + 1.2 = 22.75

therefore, it takes Erika 1.2 minutes per mile less than Rita.

On average, Erika is much slower than Rita by 1 minute.

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Since, There are two sets of data: Erika's and Rita's.

Now, we have to find the average values for each of both and compare them.

We would assume that the order of the presentation of data points is alternating,

first for Erika followed by Rita.

Hence, To illustrate what I mean, let's say

in Day 1, Erika's time is 20 and Rita's time is 21.25.

In Day 2, Erika's time is 21.5 and Rita's is 24.75.

And so on and so forth.

So, We get;

Erika's average is,

= (20+21.5+22.75+23.25+20.25)/5

= 21.55

Rita's average is,

= (21.25+24.75+23+23+20.75)/5

= 22.55

Hence, On average, Erika is much slower than Rita by 1 minute.
