Answer:
A, B, C and D. are solutions.
Step-by-step explanation:
x^2 + y^2 = 13
x^2 - y^2 = 5
Check which roots fit the original equations:
If x = 3, A gives
9 + y^2 = 13 giving y = +/- √4 = 2 or -2.
Now plug in x = 3 and y = 2 in the second equation:
9 - (2)^2 = 5
Therefore (3,2) is a solution of the 2 equations.
Following the same procedure for B, C and D:
B. Substituting x = 3 and x = -2 fits both equations so (3, -2) is a solution.
The same is true for C and D.
The answer to your question is b 3 to the 6power. The reason why is there are 6 3 so instead writing 3*3*3*3*3*3 you can just do 3 to the 6 power.
Hope this helps:)
so who is this about? no persomn no answer my guy and without vontext its ahrd to understand
Answer:
$1.40
Step-by-step explanation:
First, 8% of $45
45*0.08=3.6
45+3.6=48.6
50-48.6=1.4
