system of equations with the solution (4, -3).

Between (5,10) and (15,70), a line runs. As a result, the slope of the line through the supplied locations is 3.

A line's steepness and direction are measured by the line's slope.

Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

Any two different points on a line can be used to calculate the slope of any line.

A line's slope is determine by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.

Two locations located on a straight line can be used to determine a line's slope. We can use the slope of line formula if we know the two spots' coordinates. These two points' coordinates should be-

P1 = (x1, y1) and P2 = (x2, y2)

Hence, Between (5,10) and (15,70), a line runs. As a result, the slope of the line through the supplied locations is 3.

The explicit formula for the geometric sequence 6, -24, 96, ... is

Every term in a geometric series is obtained by multiplying the term before it by the same number called the common ratio

The common ratio is denoted by the number r. It can be calculated by dividing any term in the sequence by the term before it.

For the given sequence the first term is a = 6

The common ratio is solved as follows

a * r  = second term

6 * r = -24

r = -24/6

r = -4

check

-24 * -4 = 96 correct

The nth term of a geometric sequence

= ar^(n - 1)

= a * -4^(n - 1)

checking for the third term

= a * -4^(n - 1)

= 6 * -4^(3 - 1)

= 6 * -4^(2)

= 6 * 16

The bags of chips sold are 111.

The percentage is the term use to tell the hundredth part of something.

Given that, The snack bar sold 75% of its inventory of bags of chips, and the snack bar still has 37 bags of chips,

Let the original number of bags of the chips be x,

Since, 75% is already sold, so left number of bags are = 100%-75% = 25%

Therefore,

25% of x = 37

x = 37x4

x = 148

The number of bags sold = 75% of 148

= 75x148/100

= 111

The correct long division is shown below.

This means [tex]\frac{15}{8} = 1.875[/tex] in which you can use your calculator to verify this.

Answer:

  see attached

Step-by-step explanation:

Given the equation for a line, y +3 = (x -6), you want to identify the slope and a point on the line, then graph it.

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)

Comparing this to the given equation, you can see ...

This tells you the slope is 1 and a point on the line is (6, -3).

You graph this equation by plotting point (6, -3) and drawing a line through it that goes up 1 unit for each 1 unit to the right. A graph is attached.

__

Additional comment

If you like, you can rearrange the equation to slope-intercept form by subtracting 3:

  y +3 -3 = (x -6) -3

  y = x -9

This tells you another point is -9 on the y-axis.

The relation is:

(1, 2), (-3, 5), (6, 6), (-2, 0), (1, 2)

Is a function, because each element in the domain is mapped to a single element in the range.

A relation maps elements from one set, called the domain, into another set, called the range.

For example, the element x mapped into element y is written as (x, y).

Particularly, a relation is a function if each element from the domain is mapped into only one element of the range.

So, if we had two points like (2, 4) and (2, 5), then the relation is not a function (because the element 2 is mapped into two different elements of the range).

Here the relation is:

(1, 2), (-3, 5), (6, 6), (-2, 0), (1, 2)

So the input x = 1 appears twice, but both times is mapped to the same element, so this relation is a function.

The number of liters in the tank after 109 seconds is 60.5 liters.

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

2.5 liters = 1 minute

2.5 liters = 60 seconds

Multiply 109/60 on both sides.

109/60 x 2.5 liters = 109 seconds

4.5 liters = 109 seconds

This means,

4.5 liters is drained after 109 seconds

In 11.56 years the given amount of $ 900 will be double.

The interest charged on a loan or deposit is known as compound interest which depends on both the principal amount and rate of interest.

The formula  used for

where P = Principal amount

r = Rate of interest in decimal

n = Number of compounds per year  

t = Time period  

Here from the given data,

Principal amount, p = $ 900

Rate of interest, r = 6% = 6/100 = 0.06

Number of compounds, n = 12    [ ∵ compounded mothly ]

Here we need to find the time period

Assume that after 'n' years the amount will be doubled i.e $ 1800

From the given problem,

Amount, A = 900(1+0.06/12)¹²ⁿ        

= 900(1+0.06/12)¹²ⁿ

= 900(1 + 0.005)¹²ⁿ

= 900 (1.005)¹²ⁿ  

As we assumed after 'n' years the amount is $ 1800

=> 900 (1.005)¹²ⁿ = 1800  

=> (1.005)¹²ⁿ = 2    

Apply to log on both sides

=> log (1.005)¹²ⁿ = log 2

=> 12n log(1.005) = log 2

=> 12n = log 2/log(1.005)

[ use calculator for log (1.005) and log 2]

=> 12n = 0.301029996/ 0.00216606176  

=> 12n = 138.975722

=>  n =  11.5813102

=>   n = 11.56

In 11.56 years the given amount of $ 900 will be double.

By setting up the equation, we get the system of linear equations are

9x + 7y = 77

3x + 5y = 49

solving these equation Cost to rent a chair = $1.75

cost to rent a table = $8.75

A system of linear equations is a collection of one or more linear equations involving the same variables.

There are several methods for solving systems of linear equations, including:

Graphing: One way to solve a system of linear equations is to graph each equation on the same set of axes and look for the point of intersection. This method is useful when you want to visualize the solution, but it can be time-consuming if you have a large system of equations.

Substitution: The substitution method involves solving one of the equations for one of the variables and substituting this expression into the other equation. This will result in an equation with only one variable, which you can then solve.

Elimination: The elimination method involves adding or subtracting the equations in such a way that one of the variables is eliminated. This will result in an equation with only one variable, which you can then solve.

etc.

To solve the system of equations 9x + 7y = 77 and 3x + 5y = 49, you can use the substitution method.

First, solve the first equation for y:

9x + 7y = 77

7y = -9x + 77

y = (-9/7)x + 11

Now substitute this expression for y into the second equation:

3x + 5((-9/7)x + 5(11) = 49

3x - (45/7)x + 55 = 49

solving for x :

x = 1.75

Now substitute this value for x back into the first equation to find y:

y = 8.75

Answer:

C

Step-by-step explanation:

Because it says -8 x 7, the * is negative and the 7 is positive.

The units digit of the double factorial notation is the units digit of the product of all the even integers from 2 to 8, which is 8! The units digit of 8! is 8, so the answer is 8.

Factorials are mathematical operations symbolized by an exclamation point following a number. To find the factorial of a number, such as 5, write it down as 5! then multiply it by all the positive integers less than 5, including 1. Therefore, 5! is equivalent to 5 x 4 x 3 x 2 x 1, or 120. Factorials are frequently employed in mathematical equations and computations, especially in probability and statistics, where they are used to calculate the number of combinations or permutations that may be made from a given collection of numbers or variables.

Compute the Euclidean distance between the following points:

p_1 = (-2, 3) and p_2 = (5, -1)

The Euclidean distance between points (x_1, y_1) and (x_2, y_2) is:

sqrt((x_1 - x_2)^2 + (y_1 - y_2)^2)

Substitute (x_1, y_1) = (-2, 3) and (x_2, y_2) = (5, -1):

= sqrt((-2 - 5)^2 + (--1 + 3)^2)

(-1)^2 = 1:

= sqrt((-2 - 5)^2 + (1 + 3)^2)

-2 - 5 = -(2 + 5):

= sqrt((-(2 + 5))^2 + (3 + 1)^2)

2 + 5 = 7:

= sqrt((-7)^2 + (3 + 1)^2)

Multiply each exponent in -7 by 2:

= sqrt((-1)^2×7^2 + (3 + 1)^2)

7^2 = 49:

that means for an exponential distribution we have

P(X < x) = 1 - e^(-Lx)

L = 1/mean = 1/12500

and we need to find x, so that P(X <x) = 0.0425 (that is 4.25% converted into a probability).

so, we get
