How to graph 14x+18y=126

Mathematics
1 answer:
Burka [1]2 years ago
4 0

  • We need to rearrange this into y=my+c
  • Subtract 14x from both sides
  • 18y=-14x+126
  • Divide both sides by 2
  • 9y=-7x+63
  • Divide both sides by 9
  • y=\frac{-7x+63}{9}=\frac{-7x}{9} +\frac{63}{9}
  • Plot the point (0, 63/9)
  • Then pick some x values and put them into the equation to find the respective y values
  • Then plot those points
  • Finally join up those points

Solve for D <br><br><br><br><br><br> Thanks!!
Verizon [17]

Answer:

The answer is d = C/pi.

Step-by-step explanation:

To solve this equation for the variable d, we must isolate it on the right side of the equation.  It is currently being multiplied by pi, so to reverse this action, we should divide both sides of the equation by pi.

c = (pi) * d

c/pi = pi/pi * d

c/pi = d

d = c/pi

Therefore, the answer is d = C/pi.

Hope this helps!
