It’s a straight line increasing
Does that answer your question?
Answer:
senior tickets sold: 12
child tickets sold:8
Step-by-step explanation:
Let
x= amount of senior tickets sold
y= amount of child tickets sold
For the first equation, it should look like:
200=14x+4y
For the second equation, it should look like:
92=7x+y
So this is a systems of equations problem. So I will use substitution as it is easier:
1.) Take one of the equations (in this case ill take 92=7x+y) and make one variable have a value, in this case ill isolate the y.


2.) Take the value of y and plug it into "y" into the other equation to solve "x"

<u><em>(editor's note:instead of dividing it by 14, I multiply by 1/14 as it would look complicated in the equation solving steps)</em></u>
3.) Then plug the value of "x" to one of the equations to solve for "y" (which I'll use the 92=7x+y)

Answer:
B
Step-by-step explanation:
just multiply 8.50 times 4 and all the numbers in the problem
Answer:
3
Step-by-step explanation:
The slope of the line passing through the points is
m = (y2-y1)/(x2-x1)
= ( 1-2)/(8-5)
= -1/3
The slope that is perpendicular is the negative reciprocal which is
- ( 1/(-1/3)
+ 3/1
The perpendicular slope is 3
Answer:
.
Step-by-step explanation:
The given series is,

When we substitute
, we get the first term, which is 
This implies that,

.
The common ratio is

The finite geometric sum is given by the formula,
.
Since there are 9 terms, we find the sum of the first nine terms by putting
in to the formula to get,
.
