Answer:
I am pretty sure it is A
Step-by-step explanation:
Answer: 1/16
Step-by-step explanation:
Answer:
85.2
Step-by-step explanation:
first divide 53.25 by 5 to get the per hour amount.
Then times that number by 8.
3x - 2y = 13
-2y = -3x + 13
y = 3/2x - 13/2...slope is 3/2, y int is -13/2
2x + 3y = -16
3y = -2x - 16
y = -2/3x - 16/3...slope = -2/3, y int is -16/3
perpendicular lines will have negative reciprocal slopes. To find the negative reciprocal of a number, flip the number and change the sign.
On the 1st equation, the slope was 3/2....find its negative reciprocal.....flip it, making it 2/3....change the sign...making it -2/3. So the negative reciprocal of 3/2 is -2/3.
So if one equation has a slope of 3/2 and another equation has a slope of -2/3, then these lines are perpendicular <==
sqrt (7/8) = sqrt(7)/sqrt(8) = sqrt(7)/ (sqrt(4*2)
sqrt(7)/(2sqrt(2))
no sqrt in the denominator
sqrt(7) * sqrt(2) sqrt (14) sqrt(14)
------------------- = ----------- =-------
2 sqrt(2) *sqrt(2) 2 (2) 4
Answer: sqrt(14)/4
