Equivalent systems of equations review
Step-by-step explanation:
We're given two systems of equations and asked if they're equivalent.
x + 4y = 8 (1)
4x + y = 2 (2)
Interestingly, if we sum the equations in System A, we get:


Replacing the first equation in System A with this new equation, we get a system that's equivalent to System A:


This is System B, which means that System A is equivalent to System B.
Answer:
{Rounded to the nearest Hundredths place}
1) Mercury= 170.55
2) Venus= 277.86
3) Earth= 389.62
4) Mars= 401.29
Explanation:
Mercury: 3.3022 x 10^19= 170.549894825 which rounds to 170.55
Earth: 5.9722 x 10^24= 389.618945662 which rounds to 389.62
Venus: 4.8675 x 10^21= 277.855972801 which rounds to 277.86
Mars: 6.4185 x 10^23= 401.287714067 which rounds to 401.29
•So smallest to largest would be• 170.55, 277.86, 389.62, and 401.29
[I hope this helps][Sorry if it doesn’t make sense]
(-2,2) and (-2,-3) are the bottom vertices, since (3,-3) is the top you can tell that it is the upper left vertex since it lines up with (2,-3), so the fourth vortex would line up with (-2,2) and would therefore be C. (3,2)
