<h3><em>This is the range of y , Ry=R−{0}</em></h3>
Answer:
2^2 your welcome
Step-by-step explanation:
line given slope = x coefficient = 1/3
Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
line slope (m) = -3
line equation formula = y = mx + b
y = -3x + b
from the point given
x = 3
y= 3
3 = -9 + b
b = 12
y = -3x + 12
45/15= 3
So 1 minute=3 cents
75*3=225=2.25 converted
75 minutes=$2.25
Since the three angles of a triangle add to give 180°
The the size of the largest angle 4 = 180° ×

= 180° ×
∴ the size of the largest angle = 80°
