What is the slope of a line perpendicular to the line with equation y = 4x + 5?

1 answer:

7 0

Perpendicular lines always have a slope that has a changed sign and is divided by one, ex: 2 => -1/2. For a slope of 4, you would make it negative and divide 1 by 4, so 4 => -1/4, making your answer A.

Answer:

136 general admission tickets were purchased, and 300 upper reserved tickets were purchased.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x is the number of general admission tickets purchased.

y is the number of reserved tickets purchased.

There were 436 tickets purchased for a major league baseball game.

This means that $x + y = 436$ , or also, $x = 436-y$

The general admission tickets cost $6.50 and the upper reserved tickets cost $8.00. The total amount of money spent was $3284.00.

This means that $6.5x + 8y = 3284$ . Since $x = 436-y$

$6.5(436-y) + 8y = 3284$

$1.5y = 450$

$y = \frac{450}{1.5}$

$y = 300$

And:

$x = 436 - y = 436 - 300 = 136$

136 general admission tickets were purchased, and 300 upper reserved tickets were purchased.
