Answer:
C
Step-by-step explanation:
The rule tells you that (x,y) -> (x + 1, y - 3), so you take each vertice and add one to the x-values, and subract 3 from the y-values.
(-6, 4) -> (-6 + 1, 4 - 3) which simplifies to (-5, 1)
(-3, -2) -> (-3 + 1, -2 - 3) which simplifies to (-2, -5)
(2, 1) -> (2 + 1, 1 - 3) which simplifies to (3, -2)
Answer: 576ft
Step-by-step explanation: We add 3 feet to this, giving us 11, then multiply this by 4 to get 44 feet for the perimeter. ... The area of a square is equal to the length of one side squared
Given : tan 235 = 2 tan 20 + tan 215
To Find : prove that
Solution:
tan 235 = 2 tan 20 + tan 215
Tan x = Tan (180 + x)
tan 235 = tan ( 180 + 55) = tan55
tan 215 = tan (180 + 35) = tan 35
=> tan 55 = 2tan 20 + tan 35
55 = 20 + 35
=> 20 = 55 - 35
taking Tan both sides
=> Tan 20 = Tan ( 55 - 35)
=> Tan 20 = (Tan55 - Tan35) /(1 + Tan55 . Tan35)
Tan35 = Cot55 = 1/tan55 => Tan55 . Tan35 =1
=> Tan 20 = (Tan 55 - Tan 35) /(1 + 1)
=> Tan 20 = (Tan 55 - Tan 35) /2
=> 2 Tan 20 = Tan 55 - Tan 35
=> 2 Tan 20 + Tan 35 = Tan 55
=> tan 55 = 2tan 20 + tan 35
=> tan 235 = 2tan 20 + tan 215

Answer:
y = -4
Step-by-step explanation:
This is because any point on that line would have a y coordinate of -4 → e.g. (6, -4), (-2, -4), and it intercepts the y axis at -4.
Hope this helps!
Okie, so you have an whole number subtracted by a fraction of a number. The way to approach this problem is to convert whole number to the LCD (least common denominator) of the fraction. In this case it would be 6.
6 would be 36/6 (same number just different form)
now just subtract the numerators over the denominator
(36-1)/6 = 35 / 6 is your answer as an improper fraction. As a mixed number, it would be 5 5/6.
I hope this helps :-)
