I need help with slope (8th grade)

Mathematics
1 answer:
Triss [41]3 years ago
5 0

Answer:

(y1-y2)/(x1-x2)

Step-by-step explanation:

if you have two points from the graph then you can use them to find the slope, for example:

(2,3) and (0,5)

you would take the first point and put it in a fraction (and the second point) but the x goes on the bottom and the y goes on the top:

3/2 and 5/0

Next you put them together minusing one of the equations, but make sure that the two coordinates line up (it doesn't matter which one, in the order):

3-5/2-0

Then you solve:

-2/2

-1

which means that -1 is the slope for this

(the "/" is a fraction bar, in case you didn't already know that)

Half x s for s equals 3/10

1/2 x s, where s equals 3/10 means,

(1/2) x (3/10) which will give (3/20)

You simply multiply the numerators to get 3 and the denominators to get 20.

[SOLVED] The following data values are amperage outputs from electrical testing.
valkas [14]

The median of the data is 64, the value of Q1 is 61.5, the value of Q2 is 71, and the value of Q3-Q1 is 9.5

<h3>What is the median?</h3>

A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.

We have data:

60, 60, 61, 62, 63, 63, 65, 65, 70, 72, 73, 98

The median = (63+65)/2 = 64

Q1 = (61+62)/2 = 61.5

Q2 = (70+72)/2= 71

Q3 - Q1 = 71 - 61.5 = 9.5

Thus, the median of the data is 64, the value of Q1 is 61.5, the value of Q2 is 71, and the value of Q3-Q1 is 9.5

What is ninety nine percent of two hundred?
Yuri [45]
200 x 0.99. Or you can do 200/100 which is 2. then multiply that by 99 which gets you 99 which is 198.

Oksana_A [137]

Answer:

The correct answer is 31x + 0.5

Step-by-step explanation:

∵ 13x + 5 + 17x - 4.5 + x

To solve this correctly you must to add the coefficients of the like terms (terms who has same variables or constant terms)

∵ 13x , 17x , x are like terms ⇒ terms with same variable

  (same letters and same power)

∵ 5 , 4.5 are like terms ⇒ constant terms (numbers only)

∴ (13x + 17x + x) + (5 - 4.5) = 31x + 0.5

* <u>The error of first answer:</u>

- 18x + 17x - 4.5 + x

- She add 13x + 5 = 18x ⇒ she add unlike terms

* <u>The error of second answer:</u>

- 35x - 4.5 + x

- She add 13x + 5 + 17x  = 35x ⇒ she add 2 like terms with 1 unlike term

* <u>The error of third answer:</u>

- 30.5x + x

- She add 13x + 5 + 17x - 4.5 = (13x + 17x) + (5 - 4.5) =

  30x + 0.5 ⇒ she add 2 like terms and 2 constant terms

  and then add the 2 unlike answers

* <u>The error of fourth answer:</u>

- 31.5x

- She add 13x + 5 + 17x - 4.5 + x = (13x + 17x + x) + (5 - 4.5) =

  31x + 0.5 ⇒ she add 3 like terms and 2 constant terms

  and then add the 2 unlike answers
