2-Step equations, solve each equation

Mathematics
1 answer:
IRINA_888 [86]3 years ago
4 0

Answer:

1) 14   2) 6   3) 53   4)-2

Step-by-step explanation:

1) 15 - n/7 = 13                                    

  7*15 - 7*n/7 = 7*13

  105 - n = 91

  -n = 91 - 105

  -n = -14

   n = 14

2) 44 = - 4 + 8p

   -8p = - 4 - 44

   -8p = -48

   -p   = - 48/8

   -p  = 6

3) 21 - h= -32

   -h = -32 -21

   -h = -53

   h = 53

4) -19 = 11b + 3

   -11b = 19 + 3

   -11b = 22

     -b = 22/11

    -b = 2

    b = -2

Answer:

  • Slope: -2
  • equation: y = -2x +5

Step-by-step explanation:

The given point is the y-intercept of the line, so the slope-intercept form of the equation of a line can be used:

  y = mx + b . . . . for slope m and y-intercept b

Here, you have the slope given as ...

  m = -2

  y-intercept = 5

so the equation of the line is ...

  y = -2x +5

_____

The y-intercept is the value of y when x=0. The point (x, y) = (0, 5) tells you the y-intercept is 5.

   Looking at the figure, the rectangle has the vertexes (2,1), (3,-3), (-5,-5) and (-6,-1). The parallelogram has the vertexes (2,7), (3,3), (3,-3), and (2,1).

The area of a parallelogram is base times height. We have 2 vertical lines at x=2 and x=3, so the height is 1. And the length of the line from (3,3) to (3,-3) is 6, so the base is 6. Therefore the area of the parallelogram is 1*6 = 6.

  The rectangle is a tad trickier since it's not aligned with either the x or y axis. But we can use the Pythagorean theorem to get the lengths.

 L = sqrt((2 - -6)^2 + (1 - -1)^2)

 L = sqrt(8^2 + 2^2)

 L = sqrt(64 + 4)

 L = sqrt(68) = 2*sqrt(17)

  W = sqrt((2-3)^2 + (1- -3)^2)

 W = sqrt((-1)^2 + 4^2)

 W = sqrt(1 + 16)

 W = sqrt(17)

  And the area is length * width, so:

 2*sqrt(17)*sqrt(17) = 2 * 17 = 34

  And the total area is the sum of the areas, so

 34 + 6 = 40

  So the area of the figure is 40 square units.
