Which system of equations is satisfied by the solution shown in the graph?

A. x + 2y = 6 and x − y = 10
B. x + y = 6 and x − 2y = 10
C. x + 2y = 10 and x − y = 6
D. x + y = 6 and x − y = -10

Answers

In order to find correct system for the given graph, we need to find the slopes and y-intercepts of the lines in shown graph.

For red line we have y-intercept = 10 because it is cutting y-axis at 10.

And slope of the red line is rise/run = 1/1 that is 1.

Using slope-intercept form y=mx+b

The equation of red line is y=1x +10 or x-y =-10.

For black line we have y-intercept = 6 and slope is rise/run = -1/1 = -1.

The equation of black line is y = -1x + 6  or x+y=6.

Therefore, correct option is D. x + y = 6 and x − y = -10.

The solution shown in the graph satisfies the system of equations x + y = 6 and x - y = -10. The correct option is D.

The correct system of equations satisfied by the solution shown in the graph is x + y = 6 and x - y = -10.

To verify this, we can substitute the x and y values from any point on the graph into these equations.

If the values satisfy both equations, then the system is correct.

For example, let's take the point (2, 4) on the graph. If we substitute x = 2 and y = 4 into the equations, we get:

x + y = 6: 2 + 4 = 6, which is true

x - y = -10: 2 - 4 = -10, which is also true

Since both equations are satisfied by the point (2, 4), the correct system of equations is x + y = 6 and x - y = -10.

Therefor the correct option is D.

The pattern of values as the exponents increase is

1/3, 1, 3, 9

Comparing 1/3 to 1, we either add 2/3 or multiply by 3.

Comparing 1 to 3, we either add 2 or multiply by 3.

Comparing 3 to 9, we either add 6 or multiply by 3.

Jerry walked a dog from 6:40 am to 7:30 pm one day. If he was paid at the rate of 6$ per hour, how much did he earn that day?

Answers

Answer:

$5

Explanation:

Since Jerry walked the dog from 6:40am to 7:30am, the total minutes that he walked the dog was 50 minutes. Also a note, an hour is 60 minutes.


Since he is paid at a rate of $6 per 60 minutes, we can make a proportion.

   660=x50


From here, you have to solve for x. So cross multiply, and then simplify.

   60x=50⋅6

   60x60=50⋅6/60

   60x60=50⋅6/60

   x=5⋅6/6

   x=5

So the answer is $5.

Jerry earned about $76.98 for the day.

Jerry walked a dog from 6:40 am to 7:30 pm. To calculate how much he earned, we need to determine the total number of hours he worked.

First, we convert the end time into military time, which is 19:30.

Subtract the start time, 6:40, from the end time, 19:30.

Calculation:

From 6:40 am to 6:40 pm is 12 hours.From 6:40 pm to 7:30 pm is an additional 50 minutes, which is  [tex]\frac{50}{60}[/tex] hours or approximately 0.83 hours.Total hours worked: 12 + 0.83 = 12.83 hours.

Now, we use the rate of $6 per hour to calculate his earnings:

Earnings = Total hours * Rate per hour

Earnings = 12.83 hours * $6/hour = $76.98

Since Jerry worked a fraction of an hour, we included the approximate earnings up to two decimal places.

So, Jerry earned about $76.98 for the day.

Mario's Fine Dining charges $60.22 for its prix fixe meal plus $37.69 for every drink, d, you purchase. The equation that models the total cost (T) isT(d)=37.69d+60.22. Which value in the equation represents the rate of change?

Answers

Answer:

The value of rate of change in the equation [tex]T(d)=37.69d+60.22[/tex] is 37.69.

Step-by-step explanation:

Given the equation that models the total cost(T) is:

[tex]T(d)=37.69d+60.22[/tex]  where d is the drink you purchase.

To determine the rate of change:

1. An equation must be into the Slope-intercept form (y=mx+b).

2. m is the slope (rate of change) of the linear function.

3. b is the y-intercept of the linear function (y- intercept is where the line crosses the y-axis).

Since, the given equation is in the linear form i.e, [tex]T(d)=37.69d+60.22[/tex]

The rate of change(m) of the given equation is, 37.69.

Find the Distributive Property
8X46=8X(40+

Answers

Hey There!

8x^46=8x(40+

We move all terms to the left:

8x^46-(8x(40+)=0


Final answer:

The Distributive Property of multiplication, a fundamental concept in mathematics, was used to show that 8 x 46 = 8 x (40 + 6), which simplifies to 320 + 48 = 368.

Explanation:

The question is asking you to use the Distributive Property of multiplication, a rule in arithmetic that states that the product of a number and a sum, i.e., a(b + c), is equal to the sum of the products of that number and each term in the sum, i.e., ab + ac.

In this case,

8. x 46 = 8 x (40 + 6)

Using the Distributive Property, you would multiply the 8 by each term in the parentheses:

8 x 40 + 8 x 6.

This equals 320 + 48, which simplifies to 368. Hence 8 x 46 indeed equals 368, demonstrating the Distributive Property.

round to the place value of the underlined digit 12,387 and 2 is underlined

Answers

To round 12,387 with the thousands place underlined, we look at the digit to the right (3) and, since it is less than 5, we round down by keeping the 2 unchanged and turning all the digits to its right to zeros, which gives us 12,000.

Since the next digit (3) is less than 5, we do not increase the value of the underlined digit. Thus, we keep the 2 as it is and change all the digits to the right of it to zeros, resulting in the rounded number 12,000.

This concept is similar to the general principle applied when rounding numbers, which involves looking at the digit immediately to the right of the target place value. If it's 5 or greater, we round up. Otherwise, we round down. Examples of rounding numbers in different situations include:

Significant figures: Rounding an answer like 2,085.5688 to five significant figures would result in 2,085.6 because the first digit to be dropped is greater than 5.

Limiting the final answer to a certain place value: When adding 6527.23 and 2, the answer must be reported as 6528 because the digit 2 has no decimal places that would be significant, so we can only report to the ones place.

When working with calculations such as 119.902, if we need to limit our answer to tenths based on significant figures, we round down to 119.9.

What is Proportion?

Two or more ratios setting to be equal to each other is termed as proportion.

If two quantities are directly proportional, if one increases. other also increases and if one decreases, other also decreases.

If two quantities are inversely proportional, if one increases other decreases and if one decreases, other increases.

Solve this problem using proportional concept.

Jannelle can drive an average of 295 miles on one tank of gas. We have to find the miles she can drive on 16 tanks of gas.

Miles Jannelle can drive on one tank of gas = 295 miles

Miles Jannelle can drive on 16 tanks of gas = 16 × 295

                                                                        = 4720 miles

hope this helps!


Final answer:

The question is a math problem involving the sum of fractions reflecting food choices at a wedding. By considering fractions and its equivalent counts, we find that the total number of guests at the wedding was 96.

Explanation:

The subject of this question is mathematics, specifically a problem dealing with fractions. To determine the total number of guests at the wedding, we need to consider all the meal choices and their counts. 1/3 of the guests chose pasta and 5/12 of them chose chicken. The rest, as given, were 24 guests who chose beef. To find the total, we need to convert fractions to a common denominator. In this case, 12 is a convenient choice:

Pasta: 1/3 = 4/12

Chicken: 5/12

So, 4/12 + 5/12 = 9/12 of the guests chose either pasta or chicken. Since the remaining guests chose beef, that means 24 guests represent the remaining 3/12 of the total guests. Therefore, if 3/12 of the guests is 24, one 'part' (1/12) is equal to 24/3, which is 8. That means the total number of guests (12 parts) is 12 * 8, which equals 96. Therefore, there were 96 guests at the wedding.
