Answer:
(3, -7) and (1, 2) are solutions to the equation
Step-by-step explanation:
Simply replace the (x, y ) pair of values in the equation and see if the equality holds:
Pair (0, -8) :
9 (0) + 2 (-8) = -16 therefore this pair is NOT a solution of the equation
Pair (3, -7):
9 (3) + 2 (-7) = 27-14 = 13 therefore this pair IS a solution of the equation
Pair (1, 2):
9 (1) + 2 (2) = 9 + 4 = 13 therefore this pair IS a solution of the equation
Pair (4, -5):
9 (4) + 2 (-5) = 36 - 10 - 26 therefore this pair is NOT a solution of the equation
The answer is 4, it's a four Dallor difference
50 employees work 40 hours/week at $20/hour.
Their combined regular hours salary is 50 * 40 * $20 = $40,000.
15 employees worked 4 hours at $30/hour.
Their combined overtime salary is 15 * 4 * $30 = $1,800.
The total payroll is the regular hours plus the overtime:
$40,000 + $1,800 = $41,800
The overtime is the following percentage of the total payroll:
$1,800/$41,800 * 100% = 4.3%
Answer: 4.3%
ABC is an isosceles triangle so AB = AC
Plug in
8x - 4 = 5x + 11
3x = 15
x = 5
BC = 4x - 2 = 4(5) - 2 = 20 - 2 = 18
Answer
BC = 18 units
Your answer would be -20 ft per sec/5 = -4 ft/sec
