Answer:
A
and
D
Step-by-step explanation:
Because if you simplify the equation theb you get 8x+4 therefore D is equivalent to it. A is also equal to D which make it equivalent to the equation as well.
Answer:
-7r^2+12r-8
Step-by-step explanation:
So the first thing you do is distrubute.
8(R+6) - 2R = 8R+48-2R = 6R + 48
Answer is 6R + 48.
We have been given a system of equations. and . We are asked to find the solution of our given system of equations.
The solution of our given system of equations will be the point, where both lines will intersect.
To find intersection point, we will equate both equations as:
Now we will substitute in equation and solve for y.
Therefore, the point is the solution of our given system of equations.
We can verify our answer by graphing both equations.
First leave y by itself. first subtract 4x by both sides. 5y=10-4x. then divide 5 by both sides y= 10-4x/5. y=5-4x/5. when graphing in sert the x into the equation to give you y.
