Step-by-step explanation:
1/3= 3/9
5x + 10y = 360
y = 2x + 1
5x + 10*(2x + 1) = 360
5x + 20x + 10 = 360
25x = 350
x = 14
y = 2x + 1
y = 2*14 + 1
y = 29

What homework do you need help with
Answer:
m [slope] = 1/12
Step-by-step explanation:
If a line is perpendicular (90 degrees, forms a right angle) to another, the slope of the line must be an opposite reciprocal of the other. The opposite reciprocal of m is -1/m.
An opposite reciprocal is created by flipping the numerator and denominator, and making it negative.
Therefore, if m is -12 it's opposite reciprocal is -1/-12 = <u>1/12</u>.
