Which equation represents the line that contains the point (-2, 9) and is perpendicular to the line y = 2x + 6?

2 answers:

7 0

Y=-1/2x+8

perpendicular means slope is opposite reciprocal so it would be -1/2

y=-1/2x+b
Plug in points and solve for b
B=8

At the movie theatre, child admission is $6.10 and adult admission is $9.20 . On Thursday, three times as many adult tickets as

natita [175]

Answer:

21 child tickets.

Step-by-step explanation:

Let x represent number of adult tickets and y represent number of child tickets.

We have been given that on Thursday, three times as many adult tickets as child tickets were sold. We can represent this information in an equation as:

$x=3y...(1)$

We have been given that at a the movie theater, child admission is $6.10 and adult admission is $9.20.The all tickets were sold for a total of $707.70. We can represent this information in an equation as:

$9.20x+6.10y=707.70...(2)$

Upon substituting equation (1) in equation (2), we will get:

$9.20(3y)+6.10y=707.70$

$27.6y+6.10y=707.70$

$33.7y=707.70$

$\frac{33.7y}{33.7}=\frac{707.70}{33.7}$

$y=21$

Therefore, 21 child tickets were sold on Thursday.
