Which equation shows a proportional relationship? *

y= -2x +5
y= 3+ 5x
y= -3x

Answers

Answer 1

Answer:

y= -3x

Step-by-step explanation:

The graph of a line with a proportional relationship would have the line go through the origin.

Since the 'y=-3x' equation only shows the slope of the line, it goes through (0,0), or the origin, as it's y-intercept.

y= -3x should be the correct answer.

Hope this helps.

A figure with 4 sets of parallel sides is graphed on a grid. The figure is then rotated 90 degrees clockwise. How many pairs of parallel sides does the figure have after the rotation?

Answers

Answer:

Step-by-step explanation:

After being rotated by 90 degrees, the figure has 4 pairs of parallel sides.

What is 90° rotation of an object?

The transformation P(x, y) P' can be used to represent a 90° rotation for any point in the plane (x, y) (-y, x). This transition can be produced by applying two reflections.Transformation involves moving a shape from one position to another  

Given data ,

A figure with 4 sets of parallel sides is graphed on a grid

The figures with 4 sets parallel sides are : Rhombus, Square , Rectangle

The figure is then rotated 90° clockwise

Now ,

90 degrees clockwise transformation carries the square , rhombus as well as the rectangle onto itself that is after rotation there will be 4 pairs of parallel sides

Hence , after being rotated by 90 degrees, the figure has 4 pairs of parallel sides.

In a neighborhood of 72 families. 18 families on one or more cats. Write the number of families who own one or more cat as a fraction. Then write the fraction as a decimal.

Answers

Answer:

0.25

Step-by-step explanation:

The fraction is 18/72. The decimal is different. If you divide 72 by 18, you get 4. That tells you how it is in a quarter, aka four pieces. Divide 100 by 4, you get 25. That’s why the  answer is 0.25

as below

Step-by-step explanation:

6= x^2 + 19

x^2=6-19

x^2 = - 9

sqrt ( x^2) = sqrt (-9)   :o   sqrt of a negative?  yes.. use i for the negative.. this is a complex number  .. hope you've been studying those

x = i* sqrt (9)

+- x = i3  so there are technically two answers

A pizza restaurant charges a flat fee for a plain cheese pizza. There is an extra charge for any additional toppings. The cost of a pizza can be determined from the equation c=0.5m+5, where M is the number of additional toppings and see is the cost of the pizza ordered. What are the interpretations of slope and Y intercept in the equation?

Answers

Answer:

The y-intercept is the flat fee for the pizza - $5. The slope is the charge for each additional topping - $.50

Step-by-step explanation:

c=.5m+5

y=mx+b - slope intercept formula

In the slope-intercept formula, the 'b' is the y-intercept. We know that would be the flat fee because there is no variable attached to it.

In that formala, m is the slope and is attached to a variable, x. This problem uses the variable m instead of x, but we can see that the slope for .5m would be .5. Thus, that's the charge for the toppings. Hope that helps!

Andrew participated in a bicycle race. The total distance covered was 56
miles. If he cycled at a constant rate of 14 miles per hour, how much time
did Andrew take to complete the race?
O A) 1 hr.
B) 4 hr.
C) 7 hr.
OD 9 hr.

Answers

(B) 4 hr is the correct answer.

Explanation :

★ Speed of body is defined as the ratio of distance travelled to the time taken[tex].[/tex]

speed = distance/time

Given that,

distance = 56 miles

speed = 14 miles per hour

By substituting the values, we get

⭆ time = distance/speed

⭆ time = 56/14

Solve 3kx + 24 = 9 kx for x.

Answers

Answer:

Step-by-step explanation:

3kx + 24 = 9kx

First subtract 3kx to both sides.

24 = 9kx  - 3kx

24 = 6kx

Divide both sides by 6

24/6 = kx

4 = kx

Divide both sides by k.

4/k = x

A Sand dune stands 5 feet above sea level. the hill is eroding at a rate of 1 foot per 20 years. let y represent the height of the sand dune after x years. which equation represents the situation

Answers

Answer:

5 - (1 + 20) = yx

Step-by-step explanation:

So if 5ft is the original height, we would need to distribute that to decrease in the following years. That is where the 5 - comes from. Next we know that is it is eroding 1 foot in 20 years so that is 5- (1+20) You HAVE to distribute that and not add. Then it equals y the height of the dune in x, the years. Honestly 5 feet above sea level is kinda puny for a sand dune ;P.

Q.1) Read this short passage and answer the question below:Excerpt from The Little MermaidBy Hans Christian Andersen"Come, little sister," said the other princesses; then they entwined their arms and rose up in a long row to the surface of the water, close by the spot where they knew the prince's palace stood. It was built of bright yellow shining stone, with long flights of marble steps, one of which reached quite down to the sea. Splendid gilded cupolas rose over the roof, and between the pillars that surrounded the whole building stood life-like statues of marble. Through the clear crystal of the lofty windows could be seennoble rooms, with costly silk curtains and hangings of tapestry; while the walls were covered with beautiful paintings which were a pleasure to look at. In the center of the largest saloon a fountain threw its sparkling jets high up into the glass cupola of the ceiling, through which the sun shone down upon the water and upon the beautiful plants growing round the basin of the fountain. Now that she knew where he lived, she spent many an evening and many a night on the water near the palace. She would swim much nearer the shore than any of the others ventured to do; indeed once she went quite up the narrow channel under the marble balcony, which threw a broad shadow on the water. Here she would sit and watch the young prince, who thought himself quite alone in the bright moonlight. She saw him many times of an evening sailing in a pleasant boat, with music playing and flags waving. She peeped out from among the green rushes, and if the wind caught her long silvery-white veil, those who saw it believed it to be a swan, spreading out its wings.Based on details in the story, the reader can conclude that the little mermaid A) cares more about humans than her sisters do B) loves the beauty of the princes palace more than her home C) is unhappy with her life below the sea D) is too shy to try and talk to the prince Q.2) Which sentence shows that the little mermaid has been affected by the Prince? A) It was built of bright yellow shining stone, with long flights of marble steps, one of which reached quite down to the sea. B) Here she would sit and watch the young prince, who thought himself quite alone In the bright moonlight. C) Through the clear crystal of the lofty windows could be seennoble rooms, with costly silk curtains and hangings of tapestry; while the walls were covered with beautiful paintings which were a pleasure to look at.
