blsea [12.9K]

Hi.

First, I am going to give you some definitions.This will help you do the problems.

-Complementary angles have a combined sum of 90.

- Supplementary angles have a combined sum of 180.

10. 40+50=90- so YES.

12. 159+20= 179.-so NO.

Make sure you learn the definitions properly next time!

The perimeter of the rectangle below is 65 inches.
Tems11 [23]

Answer:

A :-) Given -

perimeter = 65 inches

Side ‘a’ = 2x

Side ‘b’ = 3 1 by 4x + 1

Solution -

Perimeter = 65

= a + b = 65

= 2x + 3 1 by 4x + 1 = 65

( 3 1 by 4 = 4 x 3 + 1 = 12 + 1 by 4

= 13 by 4 )

= 2x + 13 by 4x + 1 = 65

= 2x + 13 by 4x = 65 - 1

= 2x + 13 by 4x = 64

= 15 by 4 x = 64

= x = 64 x 4 by 15

= x = 256 by 15

= x = 17.06

.:. The value of x = 17.06.

write the equation if the line in slope- intercept form that passes through (7,-4) with a slope of -1.
QveST [7]

9514 1404 393

Answer:

  y = -x +3

Step-by-step explanation:

The point-slope form can be a useful place to start.

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

You require the line ...

  y -(-4) = -1(x -7)

  y = -x +7 -4 . . . . . . . . eliminate parentheses, add -4

  y = -x +3 . . . . . . . . . slope-intercept form
