-x + 5y = 8....we need to put this in y = mx + b form to find the slope...the slope will be in the m position.
5y = x + 8
y = 1/5x + 8/5.....so the slope is 1/5...a perpendicular line will have a negative reciprocal slope. So the slope we need is -5.
y = mx + b
slope(m) = -5
(7,-1)..x = 7 and y = -1
now we sub and find b, the y int
-1 = -5(7) + b
-1 = -35 + b
-1 + 35 = b
34 = b
so ur perpendicular line is : y = -5x + 34
the original slope was 1/5...a parallel line will have the same slope
y = mx + b
slope(m) = 1/5
(7,-1)...x = 7 and y = -1
now we sub and find b, the y int
-1 = 1/5(7) + b
-1 = 7/5 + b
-1 - 7/5 = b
-5/5 - 7/5 = b
-12/5 = b
so ur parallel line is : y = 1/5x - 12/5
The lowest common multiple of 3, 5, and 7 is 105, so
that's the smallest number that has those prime factors.
Every multiple of 105 is another one:
210, 315, 420, etc.
So is (105) times (any multiple of 3 or 5 or 7):
(x 3, 6, 9) 315, 630, 945, etc.
(x 5, 10, 15) 525, 1050, 1575, etc.
(x 7, 14, 21) 735, 1470, 2205, etc.
The unknown quantities are:
A = The number of adult tickets sold
C = The number of child tickets sold
Your equations could be:
8A + 5C = 550
C - 10 = A
Answer: B
Step-by-step explanation:
9/6 divided by 3/2
you flip 3/2 to 2/3 and multiply
9/6 times 2/3 = 1
