Tom has 13 new magazines to read. Let M be the number of magazines he would have left to Read after reading R of them. Write an equation relating to M to R. Then graph your equation using the axis below

Answer:

(1; 8)

Step-by-step explanation:

x = (5 + (-3))/2 = 1

y = (10 + 6) = 8

The slope of the given lines are:

Graph 1 = 1/3

Graph 2 = -1/3

Graph 3 = 3

Graph 4 = -3

To find the slope (m) of a given line on a coordinate plane, choose any two points on the line, (x1, y1) and (x2, y2), then find the slope by plugging in the values of the coordinates into the formula below:

Slope of a line (m) = change in y / change in x = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex].

Find the slope of Graph 1:

Using two points on the line, (0, 0) and (3, 1):

Slope of graph 1 (m) = (1 - 0)/(3 - 0)

Slope of graph 1 (m) = 1/3

Find the slope of Graph 2:

Using two points on the line, (0, 0) and (-3, 1):

Slope of graph 2 (m) = (1 - 0)/(-3 - 0) = 1/-3

Slope of graph 2 (m) = -1/3

Find the slope of Graph 3:

Using two points on the line, (0, 0) and (1, 3):

Slope of graph 3 (m) = (3 - 0)/(1 - 0) = 3/1

Slope of graph 3 (m) = 3

Find the slope of Graph 4:

Using two points on the line, (0, 0) and (-1, 3):

Slope of graph 4 (m) = (3 - 0)/(-1 - 0) = 3/-1

Slope of graph 4 (m) = -3

An inequality to determine the number of levels you can play in 60 minutes is 5 + 7l ≤60

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Here, it is given that :

Time for setting up the game = 5 minutes

Time to play each level = 7 minutes

Let  l represent the number of levels played.

So, Time to play l levels = 7l

So, b = 5+7l

Now we are required to  Write an inequality to determine the number of levels you can play in 60 minutes.

So, the inequality becomes :

5 + 7l ≤60

Hence an inequality to determine the number of levels you can play in 60 minutes is 5 + 7l ≤60

Solution:

LCM of 9 and 19 is the smallest number among all common multiples of 9 and 19.

The first few multiples of 9 and 19 are (9, 18, 27, 36, 45, 54, . . . ) and (19, 38, 57, 76, 95, . . . ) respectively.

There are 3 commonly used methods to find LCM of 9 and 19 - by listing multiples, by division method, and by prime factorization.

To calculate the LCM of 9 and 19 by the division method, we will divide the numbers(9, 19) by their prime factors (preferably common). The product of these divisors gives the LCM of 9 and 19.

In this case, we get:

Then, the LCM would be:

so that, the correct answer is:

The number of miles that is covered is  1458 miles.

The term gas mileage refers to the distance that have been covered by the car using a given volume of gas. It is common that the unit that is used to measure the volume of the gas is the US gallon.

We have been told that;

420 miles could be covered by the use of 20 gallons

1 mile can be covered by the use of 1 mile  * 20 gallons/ 420 miles

= 0.048 gallons

If 1 mile requires  0.048 gallons

x miles requires 70 gallons

x = 1 mile  * 70 gallons/0.048 gallons

Compound interest exists as the interest you gain on interest. The balance in the account after 2 years is $42266.

Compound interest simply refers to the fact that an investment, loan, or bank account's interest accrues exponentially over time as opposed to linearly over time. The word "compound" is crucial here.

'Compound interest' simply indicates earning interest on your savings, and also, eventually, on the interest that those savings earn.

The appropriate formula is

A = P(1 +r/n[tex])^{(nt)[/tex]

where P = 19,000, r = 0.4, n = 365, t = 2.

substitute the values in the above equation, we get

A = 19,000(1 +0.4/365[tex])^{(365 \times2)[/tex]

simplifying the above equation, we get

A = 42266.7592

Variance inflation factor can have a value as low as one (absence of multicollinearity). A VIF number greater than 5 or 10 generally denotes collinearity that is problematic.

The variance of bj is not inflated at all if the VIF is 1, which indicates that there is no association between the jth predictor and the other predictor variables.

VIF equal to 1 signifies that there is no correlation between the variables. A VIF of 1 to 5 indicates a moderate correlation between the variables. Variables are highly linked when the VIF is greater than correlated2.

VIF = 1.0 if all independent variables are orthogonal to one another. VIF = infinity if there is perfect correlation.

Answer: X=6

Step-by-step explanation: you can set AB plus BC to AC because they both are equal to the full line so..

2X-2+3=3X-5

First off add like terms so..

-2+3= 1 and then add 5 to the negative 5 and 1 which now leaves you with

2X+6=3X

Now you see more like terms ( 2X,3X)

Now subtract 2X from 3x which will leave you with

Answer:

(x - 3) (5x + 1)(x + 1).

Step-by-step explanation:

5x^3 - 9x^2 - 17x - 3

As the first coefficient is 5 and the last -3, so product is -15, we could try if (x-3) is a factor:

By the Factor Theorem, if x-3 is a factor then f(3) = 0.

f(3) = 5(3)^3 - 9(3)^2 - 17(3) - 3

= 135 - 81 - 51 - 3 = 0

So, x - 3 is a factor.

Now divide:

x - 3)5x^3 - 9x^2 - 17x - 3(5x^2 + 6x + 1 <------- Quotient

       5x^3 - 15x^2

                    6x^2 - 17x

                    6x^2 - 18x

                                    x - 3

                                    x - 3

                                     .......

Factoring 5x^2 + 6x + 1:

= (5x + 1)(x + 1)

So, the answer is:

(x - 3) (5x + 1)(x + 1).

The percent tip when Jayden's dinner bill is $29 is 18%.

According to the question,

We have the following information:

Bill of Jayden's dinner = $29

After adding the tip, Jayden paid $34.22.

Now, we will find the percent tip.

First, we will find the amount added to the bill.

$(34.22-29)

$5.22

Now, let's take the percent tip to be x%.

x% of 29 = 5.22

29x/100 = 5.22

29x = 522

x = 522/29 (29 was in multiplication on the left hand side. So, it is in the division on the right hand side.)

The operations which must be part of the inverse function g(x) are:

An inverse function can be defined as a type of function that is obtained by reversing or undoing a mathematical operation in a given function (f(x)).

In Mathematics, a given function (f(x)) and its inverse function has the following property f⁻¹(f(x)) = x.

Generally speaking, the inverse of multiplication is division while addition is the inverse of subtraction. In this context, we can reasonably and logically deduce that a "division by 2," followed by an "addition of 3" to the function f(x) are the operations that must be part of the inverse function g(x).

Answer:

Given:

Model : Ship = 3 : 400

The surface area of the model = 7200 cm²

To Find:

The surface area of the actual ship in m²

Let's start with the map scale given:

Model : Ship = 3 : 400

We start by adding in a unit. Usually, we choose the units associated with the model:

Model : Ship = 3 cm : 400 cm

Now, according to tot the question, we know that the actual ship is in m:

Model : Ship = 3 cm : 400 ÷ 100 m

Model : Ship = 3 cm : 4 m

The question asked for surface area, so the units have to be in squares:

Model : Ship = (3 cm)² : (4 m)

Model : Ship = 9 cm² : 16 m²

Now, that we have the units set correctly according to the question requirement, we will find 1 branch of the model:

Model : Ship = 9 cm² : 16 m²

Model : Ship = 9÷9 cm² : 16÷9 m²

Model : Ship = 1 cm² : 16/9 m²

Finally, we can find the required units by multiplying both sides with the required units:

Model : Ship = 1 cm² : 16/9 m²

Model : Ship = 1 x 7200 cm² : 16/9 x 7200 m²

Model : Ship = 7200 cm² : 12800 m²

Answer: The surface area of the ship is 12800 m²
