so equation
y = -2/3(x) - 2

answer
B. f(x) = -2/3(x) - 2
Answer 2
Let's find the slope-intercept equation of this line.  You can read off the y-intercept immediately; it's the place where x= 0 and the line crosses the y-axis.  Here that intercept is b=-2.

The coordinates of that point are (0,-2).

Now let's find the slope of the line.  Starting at (0,-2) move to the left 3 units (because -3 is the x-coordinate of the intersection of the line with the x-axis).  From (0,-2), how far UP along the y-axis to the x-axis is it?

slope = rise / run.  In this case, starting from (0,-2), and moving 3 units to the left, we get "run" = -3.  Starting from (0,-2) and moving straight up to the x-axis, we get "rise" = 2.

The slope is then m = rise / run   =  2/-3, or    m = -2/3.

Thus, the equation of this line is y = mx + b, or   y = (-2/3)x - 2.

Which is the MOST reasonable estimate of the y-intercept for this linear graph?
A) -1.7
B) -0.6
C) 0.6
D) 1.7

Answers

D. This is because the y-intercept is the point at which the x coordinate is 0. C is wrong because it's the X intercept.

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

For Q1, we can start out by turning it into a plain fraction. 16*2=32, and 32+1=33, so 16+1/2=33/2. Similarly, for 2 3/4, 2*4=8 and 8+3=11, so 2 3/4=11/4 as the size of each piece of wood. To divide them, we have the numbers 33/2 and 11/4. We first find the reciprocal of the size of a piece (switch the numerator and denominator) and then multiply the 2 fractions - 33/2*4/11=132/22=6 pieces.

Sarah buys 2 gallons of milk. There are approximately 3.875 liters in a gallon. How many milliliters of milk did Sarah buy?

Answers

3,875l= 3 875 000 milliliters
3875000×2= 7 750 000 milliliters
So she bought 7 750 000 mililiters of milk.
Final answer:

To calculate the volume in milliliters, we first convert gallons to liters (2 gallons * 3.875 liters/gallon = 7.75 liters), then convert liters to milliliters (7.75 liters * 1000 ml/liter = 7750 milliliters). So, Sarah purchased 7750 milliliters of milk.

Explanation:

Sarah purchased 2 gallons of milk, with each gallon approximately 3.875 liters. To convert liters to milliliters (ml), we should remember that 1 liter equals 1000 milliliters. So, to find the total amount in milliliters, we first convert gallons to liters (2 gallons * 3.875 liters/gallon = 7.75 liters), then convert liters to milliliters (7.75 liters * 1000 ml/liter = 7750 milliliters). Therefore, Sarah bought 7750 milliliters of milk.

Jeremy’s sister Susie, borrowed money from their mom to pay her order. Their mother has agreed to deduct an equal amount of money from Susie’s allowance each week for the next five weeks to repay the loan. What is the weekly change in Susie’s allowance?

Answers

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.

Graph of a vertical line with an x intercept of 3

Answers

I believe the slope of any vertical line is "undefined" because slope= rise(change in y values)/ run(change in x values).

Therefore, the slope for a horizontal line is
m= 0/(x2-x1).

However, for a vertical line the x-values are the values that are not changing. So, m= (y2-y1)/0. It is not possible to divide anything by zero. So, the slope of a vertical line is reported as m= undefined.

how many time more respondents chose either black or silver than red round to the nearest tenth if necessary

Silver = 0.2
Black = 0.14
Red = 0.09

Answers

In this question you are asked to compare "either black or silver" with "red" and allowed to round up to the nearest tenth. Silver is already rounded to tenth. If you round the black and red then
Silver= 0.2
Black = 0.1  ---> round down because the 0.04 value is 4, which was lower than 5
Red= 0.1 -->round up because the 0.09 value is 9, which was higher than 5

The word 'either black or silver" mean that combination of the frequency. Then the equation should be: black + silver= 0.1 + 0.2= 0.3
If you compare it with red, then: 0.3/ red= 0.3 / 0.1 = 3 times more

The floor of a canyon has an elevation of −14.5−14.5 feet. Erosion causes the elevation to change by −1.5−1.5 feet per year. How many years will it take for the canyon floor to have an elevation of −31−31 feet?

Answers

The canyon starts at an elevation of (-14.5). After each year, the elevation drops by (-1.5). The equation that could be written for this, then, would be (-14.5 - 1.5x = -31). First, we could add 14.5 to both sides of the equation to isolate the unknown. This would leave -1.5x = -16.5. Next, we can remove the negative signs so both sides of the equation are positive and easier to work with. This leaves 1.5x = 16.5. Finally, dividing both sides by 1.5 gives us "x = 11", which means that after 11 years, the canyon floor will be at -31 feet.

sometimes, people have a pet house mouse. If a mouse could travel at top speed, running 20.25 miles in 2.5 hours, how far could it travel in an hour

Answers

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:

Total Distance = 20.25 milesTotal Time = 2.5 hoursSpeed = Total Distance ÷ Total Time = 20.25 miles ÷ 2.5 hours

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.

How is interest similar to sales tax and markups? How is it different?

Answers

They are similar because they are all based on percents. They are different because interest can be added over time or multiple times. Discount is a percent that is removed and mark up is a percent that is added on. 
Final answer:

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.

Explanation:

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.
