The MOST reasonable estimate of the y-intercept for this linear graph is 0.6

Option C

The y-intercept of a linear graph is the point where the line intersects the graph on the y-axis

The slope-intercept form of the equation of a line is:

y  =  mx  +   c

where m is the slope

and c is the y-intercept

Considering the graph shown, the line intersects the y-axis on the point y = 0.6

Since the line intersects the y-axis on the point y = 0.6, the most reasonable estimate of the y-intercept of the linear graph is 0.6

Final answer:

By dividing the total distance (20.25 miles) by the total time (2.5 hours), we find that the mouse has a top speed of 8.1 mph and could therefore travel 8.1 miles in one hour if it maintained this speed.

Explanation:

To find out how far a mouse can travel in an hour at its top speed, we can use the information provided that the mouse ran 20.25 miles in 2.5 hours. This question is essentially asking us to calculate the speed of the mouse in miles per hour (mph), which is a common way to express speed. We'll use a simple division to solve this problem.

First, we divide the total distance traveled by the total time taken to find the speed:

Performing the division:

Speed = 8.1 mph

Therefore, if the mouse continued to run at its top speed, it would be able to travel 8.1 miles in one hour.

Interest, sales tax, and markups are all additional charges added to the original amount, but they differ in how they are calculated and when they are charged.

Interest is similar to sales tax and markups in that they all involve additional charges or fees that are added to the original amount.

Interest is the extra amount paid for borrowing money, while sales tax is the extra amount paid on the purchase of goods or services, and markups are the extra amount added to the cost price to determine the selling price. They all increase the total cost or price of the transaction.

The main difference is that interest and markups are calculated as a percentage of the original amount, while sales tax is calculated as a percentage of the purchase price. Additionally, interest and markups are typically charged over a period of time or for a specific duration, while sales tax is a one-time charge at the point of sale.

A unit rate means a rate for one of something.

The distance of the state park from their house is 42 miles.

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. 

We have,

Time taken to reach state park from house = 4 hours

First two hours, speed = 12 miles per hour

This can be written as:

1 hour = 12 miles

2 hours = 2 x 12 miles = 24 miles. ______(1)

The last two hours = 9 miles per hour

This can be written as:

1 hour = 9 miles

2 hours = 2 x 9 miles

2 hours = 18 miles ______(2)

From (1) and (2) we get,

24 + 18 = 42 miles

Final answer:

The question requires dividing the total amount borrowed by Susie by the number of weeks to obtain the weekly change in her allowance.

Explanation:

The question pertains to a simple mathematical calculation of equal division of a loan amount across a specified number of weeks to determine the weekly change in Susie's allowance. Although the exact loan amount isn't provided, the process would involve dividing the total sum borrowed by the number of weeks (5 weeks, as mentioned) to find out how much Susie's allowance will reduce each week.

For instance, if Susie borrowed $100, her weekly allowance would be reduced by $100 / 5 = $20 per week.

Final answer:

The weekly change in Susie's allowance is $20.

Explanation:

The weekly change in Susie's allowance can be calculated by dividing the total amount borrowed by the number of weeks she has to repay the loan. In this case, if Susie borrowed $100 and has five weeks to repay it, the weekly change in her allowance would be $100/5 = $20. Therefore, her allowance would decrease by $20 every week for the next five weeks.

If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees. If you know the measure of one angle in a pair of vertical angles, you can find the measure of the other because they are congruent.

When two lines intersect, they create angles. The properties of linear pairs and vertical angles can be used to determine these angles' measures. Linear pairs are two adjacent angles totaling 180 degrees, and vertical angles are opposite each other and are always equal.

When

two lines intersect

, they create four angles. In this formation, a couple of properties can help to determine the angle measures. The first is the concept of a

linear pair

. This is when two angles formed by intersecting lines add up to 180 degrees and are adjacent to each other. This can help when calculating one of the angle's measure if the other is known. Then, there's the principle of

vertical angles

, which are the angles across from each other when two lines intersect. Vertical angles are always equal. So if you know the measurement of one angle, you know the measurement of the angle directly across from it.

The indicated degree of likelihood as a probability value. "It will definitely get dark tonight." is:

                                    1

We know that in general the indicated degree of likelihood as a probability value lie between 0 and 1.

( For example-- The event of getting 7 when rolling a six-number cube.

As we know that the possible outcome on rolling a six-sided die is:

{1,2,3,4,5,6}

Hence P(getting 7)=0

( as none of the outcome is 7)  )

( i.e. P( getting a head or a tail on tossing a coin)=1

( since there are just two outcomes on tossing a coin i.e. head and tail will come up )

Here we have a outcome as:

"It will definitely get dark tonight."

It is a obvious event that it gets dark at night there is no other possibility.

               Hence, the answer is:

                          1

Answer:

Part A: The solution area is to the left of x=-2, over the right line y=2x+3 and below the right line y=-(3/2)x-4.

Part B: No, the point (-4,6) is not included in the solution area for the system.

Step-by-step explanation:

System of inequalities:

(1) y > 2x + 3

(2) y < -(3/2)x - 4

Part A

1) The first inequality represents the region over the line:

y=2x+3

This is a linear equation and its graph is a right line. We must graph the right line, and then shadow the area above this right line. To graph this right line we need two points, because through two points only goes one right line. Giving two arbitrary values to x, for example:

x=0→y=2(0)+3→y=0+3→y=3; Point=(x,y)→Point=(0,3)

x=1→y=2(1)+3→y=2+3→y=5; Point=(x,y)→Point=(1,5)

1) The second inequality represents the region below the line:

y= -(3/2)x - 4

This is a linear equation and its graph isaright line. We must graph the right line, and then shadow the area below this right line. To graph this right line we need two points, because through two points only goes one right line. Giving two arbitrary values to x, for example:

x=0→y=-(3/2)(0)-4→y=0-4→y=-4; Point=(x,y)→Point=(0,-4)

x=2→y=-(3/2)(2)-4→y=-3-4→y=-7; Point=(x,y)→Point=(2,-7)

The two lines intersect at the point (-2,-1). The solution area is to the left of x=-2, over the right line y=2x+3 and below the right line y=-(3/2)x-4.

Part B

No, the point (-4,6) is not included in the solution area for the system, because this point is not below the right line y=-(3/2)x-4

Part A: The purple region in the graph attached below is the solution to the given inequalities.

Part B: (-1,-1) is not included in the solution area for the system of inequalities.

In mathematics, inequalities specify the connection between two non-equal expressions.

Given the following information:

1) y > −4x − 1

2) y is less than 3 over 2 times x minus 1, this can be expressed in inequality as follows:

[tex]y < \dfrac{3}{2}x-1[/tex]

Part A:

Attaching image to describe the graph of the system with shaded area.

The red colored region corresponds to the solution of inequality of line 1)

The blue colored region corresponds to the solution of inequality of line 2)

Thus, purple colored region corresponds to the common region due to the 2 lines.

Part B:

To check whether (-1,-1) is included in the solution area for the system:

Mathematical justification:

Substituting (-1,-1) in eq1)

-1>-4(-1)-1

-1>3

This is false as -1 is less than 3.

Substituting (-1,-1) in eq2)

-1<3(-1)/2-1

-1<-3/2-1

-1<-5/2

-1<-2.5

This is also false as -1 is greater than -2.5

Thus, it is justified that (-1,-1) is not included in the solution.
