svet-max [94.6K]

Answer:

  8. yes

  9. no

  10. yes

Step-by-step explanation:

8. A horizontal line (y=3) is perpendicular to a vertical line (x=0).

__

9. A horizontal line (y=2) is parallel to a horizontal line (y=-1/2). The lines are not perpendicular.

__

10. A parallelogram is a rectangle if the sides are perpendicular. The slopes of the short sides are rise/run = -1, and the slopes of the long sides are rise/run = +1. These values have a product of -1, so the sides are perpendicular. The figure is a rectangle.

Can anybody help me on this thanks
Kamila [148]

Answer:

a) t=98

b) b=32

Step-by-step explanation:

a)  4t/7  -20=36r

     r=1

     4t/7-20=36

     \frac{4t-140}{7}=36

     4t-140=252

     4y=392

      t=98

b) 2k/5=b/2-12

k=10

20/5=b/2-12

4=\frac{b-24}{2}

8=b-24

b=32

Write an equation in slope-intercept form of the line that passes through (3,8) and (1,-2)
murzikaleks [220]

Step-by-step explanation:

let eqn be y = mx + b.

m = (-2 - 8)/(1 - 3) = 5

sub (3, 8):

8 = 5(3) + b

b = -7

therefore equation of the line is y = 5x - 7
