2x - y = 7
y = 2x - 7 this line has slope = 2
Perpendicular lines, slope is opposite and reciprocal so slope = -1/2
Answer
A . -1/2
Answer:
120 cans
Step-by-step explanation:
1 carton = 24 cans
therefore, 5 * 24 = 120
This will involve finding an arctangent.
We'll consider the woman's height as the "opposite" side of a triangle and the shadow as the "adjacent" side. The angle that the Sun makes equals the arc tangent of that angle.
tan (Sun's angle) = 71" / 36"
tan (Sun's angle) =

when we determine the arc tangent of 1.9722222222, it will equal the Sun's angle.
arc tangent of 1.9722222222 = 63.113 degrees
Answer:
No
Step-by-step explanation:
x= -9
y= 6
=> 6 = -3 . -9 - -9 = 27 + 9 = 36
