What is the slope and y-intercept? 20 points!!

Mathematics

Masja [62]2 years ago

Answer:

Slope = 2

Y-intercept = -4

Step-by-step explanation:

The slope of a function is found by finding the change in the y-values and dividing it in the change in x-values.

The change in y-values is 2 because that is the difference between each given data point. The change in x-values is 1 for the same reason.

The slope would be 2/1 which is just 2.

The y-intercept can be found by setting up the function in slope-intercept form (y=mx+b) and using the given data to solve for b. The point I chose to do this with was (2,0)

y=mx+b

y=2x+b

0=(2*2)+b

0=4+b

b=-4

So the slope is 2 and the y-intercept is -4.

In triangle ACD, what is the value of X:<br> who ever show works gets brainly.
Keith_Richards [23]

Answer:

x = 7.5

Step-by-step explanation:

Given that BE is parallel to CD and intersects the 2 other sides, then it divides the 2 sides in proportion, that is

\frac{AB}{BC} = \frac{AE}{ED}, substitute values

\frac{x}{6} = \frac{10}{8} ( cross- multiply )

8x = 60 ( divide both sides by 8 )

x = 7.5

What is the median of the following numbers? 1, 2, 2, 8, 9, 14
sesenic [268]

Answer: 5

Step-by-step explanation: The median is the middle number in the data set when the data set is written from least to greatest.

Notice that our data set is already written from least to greatest.

1, 2, 2, 8, 9, 14

Notice that in this data set, there is no middle number directly because 2 and 8 fall directly in the middle. In this situation, we take the average of these two middle numbers and divide their sum by 2.

Since 2 and 8 are the numbers that appear in the middle, we add them.

2 + 8 gives us 10.

Now we divide 10 by 2 to get 5.

So the median of this data set is 5.

A cube made out of lead has mass 12 grams. A side of the cube has length 1 cm. What would be the mass of a lead cube whose sides
lana66690 [7]

Answer:

I think it is 40.5

Step-by-step explanation:

If each 1cm cube is 12 grams, I figure the other cubes would be proportional and a 1.5cm cube comes up to be 3.375cm^3, not 1 cm^3, thus we multiply the rate to 3.375 to get 40.5 as the mass of the 1.5 cm cube
