Answer:
y + (6y -1°) = 90°
or
x = 6y -1°
x + y = 90°
Step-by-step explanation:
Two angles are y and 6y - 1
y + (6y -1°) = 90°
7y - 1° = 90°
7y = 91°
y = 13°
6y - 1 = 77°
You can go full 2π rotate around counterclockwise so the angle wouldn't be negative.
So -π/2 + 2π = -π/2 + 4π/2 = 3π/2
So (4, 3π/2) is the same point as (4, -π/2)
Step-by-step explanation:
The given equations are :
y=-x+2 ....(1)
y = -4x +7 ....(2)
From equation (1) and (2)
-x+2 = -4x +7
Taking like terms together
-x+4x=7-2
3x = 5
x = 1.667
Put the value of x in equation (1)
y=-(1.667)+2
y = 0.333
The solution of the equations are (1.667,0.333). The attached figure shows the graph for the equations.
Answer:
t + 8° > 82°
Step-by-step explanation:
Given that :
Let t = temperature when Susanne checks at 11:00
If t rises by 8 more degrees, it will break the record high temperature for that day
Record high temperature for the day = 82 degree
Hence,
Temperature at 11:00 + 8° > record high temperature for the day
t + 8° > 82°

(4/7).(-3/5) = (4.(-3))/(7.5) = -12/35
(3/5).(-6/7).(-4) = (3.(-6).(-4))/(5.7) = 72/35
6/(1/8) = 6.8 = 48
