1 vinegar to 1/2 of oil is equivalent to 2 parts of vinegar to 1 part of oil
equation is y = 2x
the second option is the correct one.
3z-4=6z-17
-3z-4=-17 (subtracted the 6z from both sides)
-3z=-13 (added the 4 to both sides)
z=
(divided both sides by -3z)
z=
Answer:
y= -1/2x+5
Step-by-step explanation:
The formula you need to use is (y-y1)=m(x-x1)
x1=the x point provided
y1=the y point provided
m=the slope
Simply plug the numbers into the equation to start.
(y-3)= -1/2(x-4) Now we need to distribute the slope to both terms inside the parenthesis.
-1/2(x)= -1/2x
-1/2(-4)= 2 Now you put them back into the equation.
(y-3)= -1/2x+2
At this point you can get rid to the parenthesis around y-3 because it is basically saying to take it times 1.
y-3= -1/2x+2 Finally to get y alone you would add 3 to both sides.
+3 +3
y= -1/2x+5
100 - 17.01 - 5 - 2 - 3 + 5 + 2 =
100 - 17.01 - 3 =
100 - 20.01 =
