So, the correct answer is (d) 150 mi.

To find out how far Greg drove, you need to multiply the speed of his car (50 mph) by the amount of time he spent driving (212 hours).

Speed = Distance/Time

Distance = Speed * Time

Distance = 50 * 212

Distance = 10600 miles

So, Greg drove 10600 miles.

It's important to note that the question is asking for the answer in miles and not kilometers.

To convert meters to miles, you can use the conversion factor 1 mile = 1609.344 meters.

To convert a measurement in meters to miles, you can multiply the number of meters by the conversion factor.

For example, if you want to convert 1000 meters to miles, you would multiply 1000 by the conversion factor of 1/1609.344 which is approximately 0.000621371.

1000 meters = 0.000621371 miles

So, the correct answer is (d) 150 mi.

Particularly there is no formula for substitution just insert the given values in the equations.

One of the methods to solve a system of linear equations in two data algebraically is the substitution method. In this method, we find the value of any one of the variables by discordant it on one side and taking every other term on the other side of the equation.

This method is a simple way to resolve a system of linear equations algebraically and find the answer to the variables.

As the name suggests, it involves finding the value of the x-variable in terms of the y-variable from the first equation and then substituting or exchanging the value of the x-variable in the second equation.

2. To calculate the average, add the three values together and divide by three.

3. The formula for a triangular method is therefore (x1 + x2 + x3) / 3.

The triangular method is a method used to calculate an average of three different values. This method is most useful when there is not enough information available to calculate a more accurate average. To calculate an average using the triangular method, the three values (x1, x2, and x3) are added together and then divided by three. The formula for a triangular method is (x1 + x2 + x3) / 3. This method is useful for finding an average when a more accurate average cannot be calculated due to a lack of data. It is also used when data points are not necessarily related, as the triangular method is less affected by outliers than other methods of calculating an average. The triangular method is a quick and easy way to find an average when more complex calculations are not possible.

Considering the expression of a line, the equation of the line that passes through the points (-6,1) and (6,7) is y=1/2x +4.

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope can be calculated using:

m= (y₂ - y₁)÷ (x₂ - x₁)

Substituting the value of the slope and the value of one of the points in y= mx + b, the value of the ordinate to the origin b can be calculated.

In this case, being (x₁, y₁)= (-6, 1) and (x₂, y₂)= (6,7), the slope can be calculated as:

m= (7 -1)÷ (6 -(-6))

m= (7 -1)÷ (6 +6)

m= 6÷ 12

m= 1/2

Considering point 2 and the slope m, you obtain:

7= 1/2×6 + b

7= 3 +b

7 -3= b

4= b

The height that Plant A has grown taller, as regards Plant B, is D. 1 / 2 inch

The height of Plant A is 5 / 6 inches while the height of plant B is 1 / 3 inches. To find how much taller Plant A is than Plant B, you need to subtract the height of Plant B from the height of Plant A.

As these fractions have different denominators, you need to find a common denominator of the bases. This common denominator would be the least common multiple of the denominators of 3 and 6.

This least common multiple is 6. Then divide the common denominator by the denominator of the height and multiply it by the numerator to give ;

= ( 5 - 2 ) / 6

Step-by-step explanation:

This is a particularly tough question. It involves polynomial division(a real laborious process) and solving using quadratic formula.

I presume your school has provided you the resources for both.

Anyways, here goes a brief explanation

To find the roots(zeros) of a polynomial, [tex]f(x)[/tex] , set [tex]f(x) = 0[/tex]  and solve for values of [tex]x[/tex]

In general, if [tex]a[/tex] is a zero of [tex]f(x)[/tex], then [tex]f(x) \div(x-a)[/tex]  will leave no remainder. In other words, it is a factor of the polynomial. It also means [tex]x - a = 0[/tex]

The given polynomial is  [tex]4 x^{3} - 15 x^{2} - 31 x + 30[/tex]

We are given that [tex]- 2[/tex]  is a zero of [tex]f(x)[/tex]. This simply means that [tex]f(-2) = 0[/tex]

Plugging [tex]-2[/tex] into the function gives

[tex]f(-2) = 4(-2)^3 -15(-2)^2 - 31x + 30\\\\ = 0 =4\left(-8\right)-15\cdot \:4-31\left(-2\right)+30[/tex]

Which indeed is 0

Here [tex]a = -2[/tex] , so [tex]x - (-2)[/tex] which is [tex]x + 2[/tex] is a factor of[tex]f(x)[/tex]. It also means that
[tex]x-(-2) = 0 \;or\; x + 2 = 0[/tex]

Steps to factor the polynomial [tex]4 x^{3} - 15 x^{2} - 31 x + 30[/tex] :

Multiplying both sides of the above by [tex]4[/tex] gives [tex]4x -3 = 0.[/tex] So [tex]4x-3[/tex] is the third factor, replacing [tex]x - \dfrac{3}{4}[/tex]

The factors of [tex]4 x^{3} - 15 x^{2} - 31 x + 30[/tex]
are:

[tex]x+2, x-5 \;and \;4x-3[/tex]
