Are you certain you wrote the question accurately?—because none of the choices is correct.
rearrange 3x+y =-5 to solve for y:
y = -3x-5
substitute -3x-5 for y into the second equation:
12x + 3y = 13
12x + 3(-3x-5) = 13
12x - 9x - 15 = 13
3x = 28
x = 28/3
y = -3x-5 = -33
solution: (28/3, -33)

Answer:
Expected number of matches that occur = 4 matches
Step-by-step explanation:
First of all, let X_i be the event that when we turn over card i if it matches the required cards face.
Thus, for example X_1 is the event that turning over one card results in an ace while X_2 is the event that turning over second card reveals a deuce.
The number of matched cards "N" is given by the sum of this indicator random variable as shown in the attached file;
Answer:
7over9 or -7over9
Step-by-step explanation:
81x power 2 - 8 = 41
(left side) (right side)
first we let the 8 from left side go to the right side,so it will be +8:
81x power 2 = 41+ 8
=49
so now we let the 81 from left side go to right side, so it will be ÷81:
x power 2= 49 over 81
and now we let the power 2 (square) go to the other side so it will become square root:
x = + - √49 over 81
at the end, you will get 2 answers which is 7 over 9 and - 7 over 9
