Answer:
Option A: Madison, (1.2,-1.6) is the correct answer.
Step-by-step explanation:
Observing Madison's solution it can be seen that he has used elimination method to solve the system. If elimination method has to be used the first equation has to be multiplied by 4
While Madison has made mistake with sign of one term in equation 1 (he has written -8x instead of 8x)
So <u>Madison's solution is wrong. </u>
Tyler has used the substitution method to solve the system of equations and has done it correctly (Calculated value of y in terms of x from equation 1 and substituted in equation 2)
The value of x=1.2 is correct, we have to find the value of y
So,
Putting the value of x=1.2 we get,
![y=2x-4\\y = 2(1.2)-4\\y = 2.4-4\\y= -1.6](https://tex.z-dn.net/?f=y%3D2x-4%5C%5Cy%20%3D%202%281.2%29-4%5C%5Cy%20%3D%202.4-4%5C%5Cy%3D%20-1.6)
The solution of given system of equations is (1.2,-1.6)
Hence,
Option A: Madison, (1.2,-1.6) is the correct answer.
6.25 quarts. this should be correct and i hope it helps
Pythagorean thereom . figure what it is and then you will know what to do
Yes it would be proportional because it goes through the origin
Answer:
The four angles are;
30 degrees, 85 degrees, 95 degrees , and 150 degrees
Step-by-step explanation:
Call the four angles of this quadrilateral A, B, C, and X (being X the smallest angle)
Then angle A is 55 degrees larger than X , therefore we can write it as X+55
Angle B is 65 degrees larger than X , therefore we can write it as X+65
Angle C is 120 degrees larger than X , therefore we can write it as X+120
Then we know that the addition of all four angles of a quadrilateral must give 360 degrees , so we have:
X + X + 55 +X + 65 + X + 120 = 360
that is:
4 X + 240 = 360
4 X = 360 -240
4 X = 120
X = 120/4
X = 30 degrees
and the other angles are:
30 + 55 = 85 degrees
30 + 65 = 95 degrees
30 + 120 = 150 degrees
