Help please! Thanks in advance
svetoff [14.1K]
So line b is (0,0) and (4, -3/2)

slope = m = y2-y1/ x2-x1

= -3/2 - 0 / (4-0 )= -3/8

now using point slope y-y1=m(x-x1)

m=-3/8 and point is (0,0) to make it easier
y-0 = -3/8 (x-0)
y=-3/8x

so we have the first line done, now another line is parallel to line b which means they have the same slope

line 2 has slope = m = -3/8
and point (0,-7)

using point slope again y-y1=m(x-x1)

y- (-7) = (-3/8) (x-0)

y=(-3/8)x -7

hope that helps and is right

The diameter of the wheel of a cart is 856 m, it will cover 2690.28 m in 56 complete revolutions.
Anvisha [2.4K]
It looks like the question you are asking is how far will the cart travel after 56 complete revolutions.

To answer this you will use the distance it will travel in 1 revolution (2690.28 m) and multiply it by 56.

2690.28 x 56 = 15655.68 meters or about 15.66 km.

If rs=2x-1 and st=4x+7 then x=<br>rt=60
kirill [66]

Answer:

9

Step-by-step explanation:

<h3>Given</h3>
  • RS = 2x - 1
  • ST = 4x + 7
  • RT = 60
  • x= ?
<h3>Solution</h3>

Since S is the point on the line segment RT,

RT = RS + ST, and

  • 60 = 2x - 1 + 4x + 7
  • 60 = 6x + 6
  • 10 = x + 1
  • x = 10 - 1
  • x = 9
