Step-by-step explanation:
since his salary is increasing by 12% you take 12% of his current salary and add that to his current salary. hope this helped ya out kid :)
This is a rule for right triangle pythagorean triples, so it is B
Substitute -2 in for x and get (9)^-2
Flip the equation so that the exponent is positive and get 1/9^2
Work it out 1/(9*9) = 1/81
The answer would be 20,670
The solution is (5, 15)
Multiply the second equation by 2 and then add through.
3x + 2y = 45
8x - 2y = 10
-----------------
11x = 55
x = 5
Then plug in to get the y value
3(5) + 2y = 45
15 + 2y = 45
2y = 30
y = 15
