Answer:

Let s be the distance to Grandma’s and v the speed they went to get to Grandma’s.

So s=8v, because it took them 8 hours to get there.

Coming back they travelled s+20 miles. Since s=8v we can write this as 8v+20 miles.

Their speed was reduced by 10mph so that’s v-10. It took them 10 hours to return so:

8v+20=10(v-10); 8v+20=10v-100; 120=2v

so v=60mph. This is their average speed going to Grandma’s.

Please see below for answers and explanation and attachments

Step-by-step explanation:

These models are best figured out using regression analysis which is a rather complicated computation but luckily there are calculators that can solve

1. The best way to approach this problem is to plot the values and see whether the model is a linear equation or a higher degree equation.

For all three cases it appears that the equations are not linear which would have suggested a model of the form y = mx + b where y = profit in $, x = hours, m is the slope (rate of increase in profit) and b a constant, the y-intercept

For example if you look at the data for the dog walker table, the increase in $ for every additional hour of service is not constant eliminating a linear model. For the first hour, the increase is $7, the second hour it is $11, the third it is $27

So i assumed a quadratic model of the form y = ax² + bx + c where y = profit in $ and x is the number of hours of service for all three businesses

There are plenty of online calculators out there which can rapidly compute the quadratic regression model parameters fitting the data and provide a level of goodness of fit of the equation through a statistic known as the correlation coefficient, r

I entered the data for all 3 rows and came up with the following results
In all the equations, y represents the profit in $ and x the hours

Step-by-step explanation:

The given fraction means to divide -3/8 by -7/54.

You are dividing a fraction, -3/8, by another fraction, -7/54.

To divide a fraction by a fraction, multiply the first fraction by the reciprocal of the second fraction.

-3/8 / -7/54 = -3/8 • (-54/7)

The LCM of both the factors x⁴+x³-x²-x, x⁴-x and 4x²-4 is discovered to be x(x+1)²(x-1).

The LCM of any two numbers is the value that is evenly divisible by the two given numbers. Least Common Multiple is an abbreviation for Least Common Multiples. It's also known as the Least Common Divisor (LCD).

The smallest integer that is a multiple of two or more numbers is known as the LCM. For instance, the LCM of 4 and 6 is 12, and the LCM of 10 and 15 is 30.

The two given expressions are:

x⁴+x³-x²-x, x⁴-x and 4x²-4

Let us simplify both these factors.

x⁴+x³-x²-x = x(x³ + x² -x -1)

                = x(x+1)(x+1)(x-1)

                = x(x+1)²(x-1)

4x²- 4 = 2²(x+1)(x-1)

Multiplying each factor with the highest power,

4x²- 4  = 2²x(x+1)²(x-1)

           = 4x(x+1)²(x-1)

Thus x(x+1)²(x-1) is the least common factor of both factors.

As a result, it is discovered that the LCM of  x⁴+x³-x²-x, x⁴-x and 4x²-4. is x(x+1)²(x-1).

If the diameter of the circle is 56cm² then the circumference of the circle is 176cm and the area of the circle is  2464cm².

A circle's area is equal to pi times the radius squared (A = πr). Discover how to apply this formula to determine a circle's area given its diameter.

The length of a circle's outline is referred to as its circumference, while the length of a form with straight sides is referred to as its perimeter. Circle circumference equals 2πr.

Diameter of the circle =56cm

Radius of circle =56/2  =28cm

Therefore,

Circumference of circle

=2πr

=2*22/7*28

The point (1, 18), in the proportional relationship, means 18 cookies will require 1 cup of flour.

In a proportional relationship graph that models the relationship between two variables, x and y, a point on the graph means the value of x that will give a corresponding value of y. It is expressed as, (x, y).

(x, y) means the quantity of x that will give a corresponding quantity of y considering the proportional relationship between variables x and y.

Thus, the graph shows a proportional relationship between the number of cups of flour (y) that was used to make different numbers of cookies.

Thus, the point (1, 18) means that for 18 cookies to be made, 1 cup of flour is to be used.

The expression that represents the situation is (5/2)x = y and the family uses 350 gallons of water for each week.

First, we convert the given fractions into improper fractions as follows;

2 1/2 = 5/2

2 1/3 = 7/3

As the showerhead uses 5/2 gallons of water per minute an expression for this situation can be given as;

(5/2)x = y

Here x is the amount of time in minutes and y represents the gallons of water used by the family each week

As the family uses the showerhead for 7/3 hours per week, we first convert the hours into minutes as follows;

(7/3) × 60 = 140 minutes

Now substituting this value in the equation (5/2)x = y;

(5/2)x = y

(5/2)140 = y

y = 350 gallons

Therefore, 350 gallons of water is used by the family per week.

y = -2x - 4

Step-by-step explanation:

First, substitute the known values into the slope-intercept form, y = mx + b, where m represents the slope of the line and b represents the y-coordinate of the point of intersection of the line and the y-intercept. We are given that the graph has a y-intercept of -4, so substitute -4 for b. The graph contains the point (-6, 8), so substitute -6 for x and 8 for y.

8 = -6m - 4

12 = -6m

m = -2

Finally, substitute -2 for m and -4 for b to write the equation of the line in the form, y = mx + b.
