Answer:

  12x -y = -87

Step-by-step explanation:

You can start with the 2-point form of the equation of a line and manipulate it to give you the standard form.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (-9 -3)/(-8 -(-7))(x -(-7)) +3

  y = (-12/-1)(x +7) +3

  y = 12x +84 +3

  -12x +y = 87 . . . . . subtract the x-term

  12x -y = -87 . . . . . . make the leading coefficient positive (per standard form)

Please help due by 10:10!!!!!!!!!!

Answer:

yes

Step-by-step explanation:

distributing gets you 8x+ 12= 2x-2 +6x+14

8x+12=8x+12

when both sides are simplified, they are equal to each other. This means that there IS a value of x that would make the perimeters equal

not sure what the drop down answers are so hope this helps

The product of two rational numbers is 2/5 , if one of them is -8/25, find the other.
Sergio [31]

Answer:

x=-5/4

Step-by-step explanation:

Let the number be  x and y

     x.y=2/5    (The product of two rational numbers is 2/5)

if  one of the number is  -8/25

x.(-8/25)=2/5

(Here Substituted the value of one of the number yoy may substitute the value -8/25 in place of x

x=(2/5) *(-25/8)    

x=-5/4

Answer:

58°

Step-by-step explanation:

<MQR = <XQL (vertically opposite angles)

28 + 5b = 70 - 2b

28 - 70 = -2b - 5b

-42 = -7b

-42/-7 = b

6 = b

<MQR = 28 + 5b

= 28 + 5(6)

= 28 + 30

= 58°

Whats 4(d+2)-2d=3(2+d)
Dmitry [639]

Simplify:

4(d + 2) - 2d = 3(2 + d)\\4d + 8 - 2d = 6 + 3d\\d + 8 - 2d = 6\\-d + 8 = 6\\-d = -2\\d = 2

d is equal to 2.
