Choose the correct answer. Choose the equation of a line that is perpendicular to the x-axis and passes through the point (1, -2). a. x= -2

b. x= 1

c. y= -2x + 1

d. y= -2​

b

Step-by-step explanation:

A line perpendicular to the x- axis is a vertical line parallel to the y- axis with equation

x = c

where c is the value of the x- coordinates the line passes through

The line passes through (1, - 2 ) with x- coordinate 1 , then

x = 1 ← equation of perpendicular line

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

the answer is 99.
