Indicate the equation of the given line in standard form. The line with slope and containing the midpoint of the segment whose e

Tems11 [23]

Answer:

x + y = -1

Step-by-step explanation:

To write the equation of a line, find the slope and use it with a point in the point slope form.

You can find the slope using the slope formula.

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{5--3}{-6-2} = \frac{8}{-8}=-1$

Substitute m = -1 and the point (2,-3) into the point slope form.

$y - y_1 = m(x-x_1)\\y --3 = -1(x-2)\\y+3=-1(x-2)$

Convert to standard form by applying the distributive property and rearranging the terms.

y+3 = -1(x-2)

y + 3 = -x + 2

x + y + 3 = 2

x + y = -1

What is the sum of 10 cubed and 25 squared?

White raven [17]

The sum is 1625.

Answer in Words: One thousand and six hundred twenty-five.

The cube of 10 is 1000.

10 X 10 = 100 (square of ten)
100 x 10 = 1000 (cube of ten)

The square of 25 is 625.

25 x 25 = 625 (square of 25)

Therefore, 1000 + 625 = 1625

the sum is 1625
