Find the slope and the y-intercept of the line y=-2/5x+5

Mathematics
1 answer:
nexus9112 [7]3 years ago
5 0

Answer:

slope is -2/5, y intercept is (0,5)

Step-by-step explanation:

The slope is the number in front of the x, or how steep the line is on the graph. In this case, it is -2/5.

The y intercept happens when x = 0, so if you make x = 0 in this equation, you find that you are left with y = 5. That gives you the point (0,5) as your y intercept.

The speed of the international space station is 27,576 kilometres per hour.
Dmitriy789 [7]
(27576km/hr)(24hr/day)(orbits/42600km)=orbits/day=15.53

So the station makes 15 FULL orbits per day

(27576km/h)(1000m/km)(h/3600s)=7660m/s

A worker at a mill is loading 10-lb bags of flour into boxes to deliver to a local warehouse. Each box holds 4 bags of flour. If
Hunter-Best [27]

Answer: 100 boxes

Step-by-step explanation:

Hi, since 1 ton = 2,000 lbs

We have to divide 10lbs by 2000 to convert the lbs in tons.

1t/2000lb = xt / 10lb

10 /2000=0.005

0.005 ton = 10 lbs (1 bag)

Each box has 4 bags

0.005 ton x 4 = 0.02 ton

So each box weights 0.02 ton

Since we need 2 tons.

Using proportions:

0.02t/1 box= 2 t / x boxes

x = 2 / (0.02/1)

x = 100 boxes  

Feel free to ask for more if needed or if you did not understand something.

Answer:

Step-by-step explanation:

Graph the points and draw an aproximate line of fit that includes two of the points. Then using point-slope form find the linear equation of that line.

10-(-4)=m(-5-4) is 14=m(-9) solve for m and find the slope is aproxx -14/9 or -1.555. Then do some fancy math to find your y intercept and you come out with an aproxx line of fit of y=(-14/9)x+(20/9). Or you could plug these points into excel and have it spit out a trendline of y=(-1.26)x+(0.467)

Which answers are examples of the Law of Detachment? Select each correct answer. If an object is a square, it is a parallelogram
MAXImum [283]

The law of detachment is a set of three sentences, such that:

  • Sentence 1 is a statement of the form If p, then q
  • Sentence 2 is a statement of the form p
  • Sentence 3 is a conclusion of the form q

Let's see which of the options follow the pattern indicated above:

Option A: If an object is a square, it is a parallelogram. The object is a square. The object is a parallelogram. - MATCHES THE ABOVE PATTERN. Hence, is an example of the Law of Detachment.

Option B: If two angles are linear pairs, the angles are supplementary. The two angles are linear pairs. Therefore, the angles are supplementary. - DOES NOT MATCH THE ABOVE PATTERN.

Option C: If it is snowing, the play will be cancelled. If the play is cancelled, the theater will refund the cost of admission. Therefore, if it is snowing, the theater will refund the cost of admission to the play. - DOES NOT MATCH THE ABOVE PATTERN.

Option D: If it is snowing, the play will be cancelled. It is snowing. Therefore, the play is cancelled. - MATCHES THE ABOVE PATTERN. Hence, is an example of the Law of Detachment.

Hence, option A and option D are examples of the Law of Detachment.
