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)

If you are going somewhere that is 60 miles away and you're going 40 miles per hour the whole time how long will it take you to
Masja [62]
Velocity * time = distance

40 (miles / hour) * t (hours) = 60 (miles)

Take note how the units work. miles/hour * hours = miles. This is an indication that a formula we picked is correct.

Now, looking at our formula (and neglecting units at this point)

40t = 60
t = 60/40
<span>t = 1.5 hours</span>

How can the distributive property be used to find 4x875?draw an array.
ICE Princess25 [194]
Break apart the 875.
8 becomes 800 the 7 becomes 70 and 5 is just 5. Now x it by the 4
800x4=3200
70x4=. 280
5x4=. 20
-------
3500
Not sure how to show the array on here

Which of the following functions illustrates a change in amplitude?
Pachacha [2.7K]

Hey there! :)

Answer:

C.

Step-by-step explanation:

For a graph to have a change in amplitude, there must be a coefficient in front of the equation, or the 'a' value.

Recall that the transformation form of a trigonometric graph is:

y = ±a(cos(b(x-h))+k

Where 'a' is the amplitude

'b' changes the period

'h' is a horizontal shift

'k' is a vertical shift

We can look at each choice and eliminate:

A. There is only a coefficient of -1 in front of the equation, which simply results in a reflection over the x-axis. This is incorrect.

B. This equation contains a b value of 2. This changes the period of the graph, not the amplitude. This is incorrect.

C. This equation contains a coefficient, or 'a' value of -2. The amplitude is changed by a factor of 2. This is correct.

D. This graph only contains a vertical shift of 1 unit up. This is incorrect.

Therefore, C is the correct answer.
