The slope of the line formula:
Next, you would have to plug in the coordinates.
Now, all you would have to do is solve and simplify it.
=
=
The slope would be .
I hope this helps!
Answer:
Gordon gets £72
Step-by-step explanation:
£240....together
Sara.....2*(3x)
Gordon.....3x
Makachy......x
2*(3x)+3x+x=240
6x+3x+x= 240
10x=240/10
x=24
Gordon 3*24= 72
-2z - xy = z + 7
You are solving for x. Note the equal sign. What you do to one side, you do to the other. Isolate the x.
First, add 2z to both sides
-2z (+2z) - xy = z + 7 (+2z)
Simplify. Combine like terms
-xy = z + 2z + 7
-xy = 3z + 7
Completely isolate the x. Divide -y from both sides
(-xy)/-y = (3z + 7)/-y
x = (3z + 7)/-y
Simplify
z = (3z + 7)/(-y) is your answer
hope this helps
Get n to one side
-1/5=-2/5n
divide both sides by -2/5
n=1/2
