plz answer fast. Helena has saved $595 to put toward snowboarding equipment and lift tickets at the hill. Each lift ticket costs $35. If she wants to have more than $420 of her savings left to spend on equipment, which inequality represents the number of lift tickets she can buy?

its d! hope i helped :)

add the point, x=-30, y=3:

y=kx

3=k*-30

3=-30k

-1/10=k

so the final answer:

k= -1/10

The zero of the function c=80-3.22n is approximately 25, which means that Jessica's CD would be completely filled after recording approximately 25 songs.

To find the zero of the function c=80-3.22n, we need to set the function to zero and solve for n. 0 = 80 - 3.22n. Solving this gives n = 24.84 (roughly).

In the context of this problem, this zero of the function means that after approximately 25 songs (as we can't have a fraction of a song), Jessica's CD would be completely filled with no remaining recording time.

It's important to note that the actual number of songs Jessica can record depends on the precise length of each song, since this equation assumes each song is the same length, which is unlikely to be strictly true in reality.

Graphs of the same function can look different based on the time frames, horizontal and vertical scalling, data grouping, and the chosen type of graph. However, it's crucial to remember that despite visual differences, the underlying mathematical function remains unchanged.

In the subject of mathematics, graphs depict the relationship between variables. The graphs of the same function can technically appear different based on numerous factors such as the range of data used, horizontal and vertical scaling, and the division of data groups. When the value of y is changing as a function of x, meaning different values of x correspond to different values of y, we can plot a graph using specific (x,y) data pairs.

This graph can appear different based on the frame of reference chosen; for example, certain timeframes might yield a linear graph, while another range could portray a curve. Similarly, the relative size of the vertical and horizontal axes can greatly impact the perception of the graph, and therefore, different scales of measurement can provide different visual perspectives of the same function.

Moreover, the type of graph used (e.g. line, bar, pie graph) also impacts visual understanding. Line graph shows the relationship between two variables, whereas a pie graph could make it easy to understand division of a whole into parts, and a bar graph can depict comparisons among different groups.

Final answer:

To calculate the total amount of ribbon Diane needs, we multiply the number of gifts (7) by the amount of ribbon per gift (2 feet). Diane will need a total of 14 feet of ribbon to decorate 7 gifts.

Explanation:

The question asks how much ribbon Diane needs to decorate 7 gifts if she uses 2 feet of ribbon per gift. To find the total amount of ribbon, we multiply the number of gifts by the amount of ribbon used for each gift. The equation for this calculation is:

Total ribbon needed = Number of gifts times Ribbon per gift

Let's plug in the values:

Total ribbon needed = 7 gifts times 2 feet/gift

Total ribbon needed = 14 feet

Therefore, Diane needs 14 feet of ribbon to decorate her 7 gifts.

To find Jimmy's speed, divide the distance he ran by the time taken. Speed = Distance/Time. which is m/t.

To find Jimmy's speed, we use the formula Speed = Distance/Time.

Therefore, Jimmy's speed, in miles per minute, is m/t.

For example, if Jimmy ran 5 miles in 10 minutes, his speed would be 0.5 miles per minute (5 miles / 10 minutes = 0.5 miles per minute).

Final answer:

To find the number of rows filled by the Springfield fifth graders, divide the total number of students by the number of students in each row.

Explanation:

To find the number of rows filled by the Springfield fifth graders, you need to divide the total number of students by the number of students sitting in each row. In this case, there were 35 students in each row.

To calculate the number of rows, divide the total number of students by the number of students in each row:

Number of rows = Total number of students / Number of students in each row

Since the total number of students is not mentioned in the question, I cannot provide a specific answer. However, if you have that information, you can substitute it into the formula to find the number of rows.

We are given the following data:

total discharge = 9.6 trillion gallons

number of household = 200 million

number of months = 6 months

So the average use of each household per month is:

average use = (9.6 trillion gallons) / (200 million households * 6 months)

average use = 8,000 gallons / household / month

So each household uses 8,000 gallons per month

Final answer:

To convert the inequality 5x - 5y ≥ 70 to slope-intercept form, we solve for y to get y ≤ −x − 14, which is most appropriately represented as option (b.) y ≤ x − 14 after rearranging terms.

Explanation:

To write the inequality 5x − 5y ≥ 70 in slope-intercept form, we need to solve for y. We start by isolating the y-term on one side of the inequality.

First, we subtract 5x from both sides: −5y ≥ 70 − 5x

Next, we divide each term by -5 (remembering to reverse the inequality symbol because we are dividing by a negative number): y ≤ (70/−5) + (5x/−5)

y ≤ −14 − x

Finally, we write x before the constant to follow conventional form:

y ≤ −x − 14

Comparing this result to the multiple-choice options, we can see that none of them exactly match the form we derived. However, we can rewrite our inequality as y ≤ x − 14 by multiplying through by -1 (which will not change the inequality because we are not dividing or multiplying the inequality itself, just rearranging the terms).

Therefore, the correct answer is (b.) y ≤ x − 14.
