in the equation x+3y=6, suppose the x-intercept was at (m,0) and the y- intercept was at the ordered pair (0,n). what is the val

VMariaS [17]

Answer:

8

Step-by-step explanation:

The x intercept is when y = 0

x + 3(0) = 6

x = 6

So (6,0) and m = 6

the y intercept is when x = 0

0 + 3y = 6 Divide by 3

y = 6/3

y = 2

the y intercept is (0,2) and n = 2

Answer

m + n = 6 + 2 = 8

The mean radius of Earth is 6,371.0 kilometres and the mean radius of Earth’s Moon is 1,737.5 kilometres.

OLEGan [10]

Answer: 29,113.2 km

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Circumference = 2 x π x radius

Replacing with the values given:

Earth's mean circumference = 2 π 6,371.0 = 40,030.2 km

Earth's moon mean circumference = 2 π 1,737,5= 10,917 km

Now, we have to subtract Earth's moon mean circumference to Earth's mean circumference:

40,030.2- 10,917 =29,113.2 km

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

The triangle has side lengths 10cm, 24cm, and 28cm, is it a right triangle? Explain please i dont understand

Nitella [24]

In every right triangle, if you add up the squares of the two
shorter sides, you get the square of the longest side. If you
don't then it's not a right triangle.

10² = 100
24² = 576

100 + 576 = 676

676 is the square of 26.
It's NOT the square of 28.

So 10 - 24 - 28 is not a right triangle.

What is the solution of -(x + 1) - 5 > 10

Pie

<span> -(x + 1) - 5 > 10
-x - 1 - 5 > 10
- x - 6 > 10
Add 6 to the both sides,
-x - 6 + 6 > 10 + 6
-x > 16
x < -16 [ changed sign 'cause changed -sign ]

In short, Your Answer would be x < -16

Hope this helps!</span>
