Answer:
what did the duck say to your mother?
Step-by-step explanation:
change in y/change in x
y2-y1/x2-x1
-1--5/0-2
-1+5/-2
4/-2
-2
slope is -2
now take one ordered pair and plug it into the equation (for this example i will use the SECOND ordered pair
y = -2x +b
-1 = -2(0)+b
-1 = b
the equation is
<h2>
y = -2x - 1</h2>
A is the correct answer because it is the only one that shows the angles that add up to 180 degrees on a line since a supplementary angle is on the line and will add up to 180. D would be correct if angles 6,4,and7 were placed together as those angles together wake a line but no, this means A is the correct answer
Answer:
The percentage of fat in the mixture is 8%
Step-by-step explanation:
Let
x -----> the percentage of fat in the mixture
we know that
The volume of milk multiplied by its percentage of fat plus the volume of cream multiplied by its percentage of fat must be equal to the total volume of he mixture multiplied by the percentage of fat in the mixture
Remember that
15%=15/100=0.15
3%=3/100=0.03
so
Solve for x
Convert to percentage
4.85 is the answer because if you subtract 51.2 from 56.05 you get your answer
