Answer:
It's true because its a rational number.
Step-by-step explanation:
Answer:
(1)
Step-by-step explanation:
We will try:
(1) y = 
x => 2 = 2 (seems legit)
(2) y = 4x => 2 = 32 (nope)
(3) y = x - 6 => 2 = 2 (yes but actually no because it is proportional relationship)
(4) y = 
x - 2 => 2 = 2 (like the above)
Answer:
D. 35 + 145 = x
The sum of the angles = 180 degree

Answer:
(-10,-10)
Step-by-step explanation:
9x-9y=0
3x-4y=10
In elimination, we want both equations to have the same form and like terms to be lined up. We have that. We also need one of the columns with variables to contain opposites or same terms. Neither one of our columns with the variables contain this.
We can do a multiplication to the second equation so that the first terms of each are either opposites or sames. It doesn't matter which. I like opposites because you just add the equations together. So I'm going to multiply the second equation by -3.
I will rewrite the system with that manipulation:
9x-9y=0
-9x+12y=-30
----------------------Add them up!
0+3y=-30
3y=-30
y=-10
So now once you find a variable, plug into either equation to find the other one.
I'm going to use 9x-9y=0 where y=-10.
So we are going to solve for x now.
9x-9y=0 where y=-10.
9x-9(-10)=0 where I plugged in -10 for y.
9x+90=0 where I simplified -9(-10) as +90.
9x =-90 where I subtracted 90 on both sides.
x= -10 where I divided both sides by 9.
The solution is (x,y)=(-10,-10)
To answer that question we need to use THE RULE OF THREE, this rule will help us solving linear relation problems.
Solution is:
The hour hand will turn (1/36)×π
The Table
Step minute hand hour hand
0-5 (1/6)×π (1/72)×π
10 (2/6)×π (1/36)×π
15 (3/6)×π = π/2 (1/24)×π
20 (4/6)×π = (2/3)×π (1/18)×π
25 (5/6)×π (5/72)×π
30 (6/6)×π = π (1/12)×π
35 (7/6)×π (7/72)×π
40 (8/6)×π (8/72)×π
45 (9/6)×π = (3/2)×π (3/24)×π
50 ( 10/6)×π ( 10/72)×π
55 (11/6)×π (11/72)×π
60 (12/6)×π = 2×π (12/72)×π = π/6
- We know that each complete minute hand turn, is a 2×π angle turn, then a 5 minutes turn is (1/12) × 2×π = (π/6)
- We will use that relationship to build the table and answer the question
If 2×π angle for a minute hand turn is equal to 1 hour, then
(2/6) angle for a minute hand turn is equal to "x" turn in the hour hand
So by Rule of Three, we proceed
2×π ( Of minute hand) ⇒ (1/6)×π (of hour hand)
(2/6)× π ( Of minute hand) ⇒ x
Solving for x
2×π × x = (2/6)× π × (1/6)×π
2× x = (2/36)×π
x = (1/36)×π
Now to build the table in 5 minutes steps:
