<1=90=3y-6
3y=96
y=96:3
y=32
9x=6z=90
x=10
z=90:6
z=15

44. BD=AC
     2x-1+3y+5=4x-y+1
     2x+3y+4=4x-y+1
      3y+y+4-1=4x-2x
       4y+3=2x
       3y+5=2x-1
        3y+5=(4y+3)-1
         3y+5=4y+2
          5-2=4y-3y
          y=3
2x=4y+3=4*3+3=15
   x=15:2
x=7,5

Answer:

m∡D=108°

Step-by-step explanation:

When a triangle has two congruent sides then their angles are equal; therefore m∡C=m∡B

And the sum of angles in a triangle is 180; therefore

m∡D=180-m∡C-m∡B=180-36-36=108

Factor completely 8x2 − 4x − 84. 4(2x − 3)(x 7) 4(2x 3)(x − 7) 4(x − 3)(2x 7) 4(x 3)(2x − 7).
gizmo_the_mogwai [7]

The factor of the given equation  8x^{2} -4x-84 will be  4(x+3)(2x-7)

<h3>What will be the factor of the given equation?</h3>

Given equation is 8x^{2} -4x-84

Now taking 2 commons from the equation

4(2x^{2} -x-21)

now splitting the equation we get

4(2x^{2} +6x-7x-21)

4(2x(x+3)-7(x+3))

4(x+3)(2x-7)

Thus the factor of the given equation  8x^{2} -4x-84 will be  

4(x+3)(2x-7)

Answer:

7. a) slope = 5

7. b) slope = 1/2

8. slope = 1

Step-by-step explanation:

slope = rise/run

rise is the vertical change, run is the horizontal change

7. a)

Pick any two points on your line. (0,0) and (1,5) are easy to work with.

The vertical change between the two points is 5

The horizontal change between those points is 1

so slope = 5/1 = 5

7. b)

Again, you can use (0,0) as one of your points. The point (2,4) is good as the second.

slope = 4/2 = 1/2

8. We don't have a graph, but we are given two points to work with, (1,4) and (5,8). Use the formula given...

m = slope = (y2-y1) / (x2-x1)

= (8 - 4) / (5 - 1)

= 4/4

= 1

I hope that helped!
