it's not a function unless it's something different
Answer:
&
Step-by-step explanation:
12.) If one ticket is $9.50, and 879,575 tickets were sold, the two need to be multiplied. 9.5 * 879,575 = 8355962.50
So the total profit was $8,355,962.50
If each theater made an equal profit of that total, then just divide it by 755, but if that's not the case, then don't do that.
13.) If the boat can carry 582 passengers, and 13,105 people had ridden the first boat, then you have to divide the number of people riding the boat by the passenger count to determine the amount of trips made.
13,105 / 582 is 22.5, but you can round it to 23, because half of a trip isn't going to be made. I'm not entirely sure when the second question means, so... sorry, can't answer that one.
Hope this helps somewhat!
To find the slope, you can either use the slope equation:
(y2-y1) / (x2-x1)
{I would recommend you remember this because you'll need to know this in the future}
or,
Just count. A slope is rise over run, so you see how far up the slope goes from one point to the other, (1), and then you see how far sideways the slope goes (2).
Going right, the slope is naturally declining downwards, so it's a negative.
The answer is B. -1/2.
Answer:
y = -1/3x + 8
Step-by-step explanation:
If two lines are perpendicular, the signs of the slope must be opposite and the slopes are reciprocals.
(basically if one is say -2/3, the other is 3/2. just flip it upside down)
So this slope is 3, so the new slope should be -1/3
The equation is now y = -1/3x + b
To find b, substitute (-9,5) in the equation
y = -1/3x + b
5 = -1/3(9) + b
5 = -3 + b
8 = b
So the equation is y = -1/3x + b
Answer:
C. x^5/2 + 6x^3/2 + 1.
Step-by-step explanation:
(x^3 + 6x^2 + x^1/2) / x^1/2
= x^(3 - 1/2) + 6 x(2-1/2) + 1
= x^5/2 + 6x^3/2 + 1.
