D should be the correct answer
Y=3x+5
Gradient=3
y-y1=m(x-x1)
If the points are (7,1)
y-1=3(x-7)
y-1=3x-21
y=3x-20 as your equation
Note: when lines are parallel they have equal gradient
Answer:
c = 6
Step-by-step explanation:
2(4 + cy) = 12y + 8
8 + 2cy = 12y + 8
12y + 8 = 8 + 2cy
12y - 2cy = 8 - 8
2y (6 - c) = 0
Divide through by 2y
(6 - c) = 0
c = 6
<h2>
Rewriting Words as Equations</h2>
To rewrite a word equation as a numerical equation, we can recognize certain keywords and change them into numbers or operations.
- <em>twice</em> = multiply by 2
- <em>difference</em> = subtract
- <em>'a number'</em> = let this be <em>x</em>
- <em>is</em> = equals
<h2>Solving the Question</h2>
We're given:
- Twice the difference of a number and 6 is 5
⇒ twice = (2 ×)
⇒ difference of a number and 6 = (x - 6)
⇒ is 5 = ( = 5)
To solve for <em>x</em>, isolate the variable:
2(x-6) = 5
2x-12 = 5
2x = 17
x =
