Answer:
1
Step-by-step explanation:
the +4 turns into -4
6-4=2 the (+4-4 on the left would cancel out)
-2x/2 would cancel out as well
2 divided by 2 = 1
you could have used a scientific calculator on google (for future reference)
Answer:
where is the graph, I don't see, but I want to help
Answer:
Step-by-step explanation:
15. (-4-3)/(-5-0)= -7/-5= 7/5
y - 3 = 7/5x - 0
y = 7/5x + 3
16. (-2-3)/(4-0)= -5/4
y - 3 = -5/4x - 0
y = -5/4x + 3
17. (-3+5)/(0+3)= 2/3
y + 5 = 2/3(x + 3)
y + 5 = 2/3x + 2
y = 2/3x - 3
18. (-2-2)/(0+4)= -4/4= -1
y - 2 = -1(x + 4)
y - 2 = -x - 4
y = -x - 2
19. y - 3 = 1/2x - 0
y = 1/2x + 3
20. y - 2 = -(x + 1)
y - 2 = -x - 1
y = -x + 1
21. perp. -5/3
y + 5 = -5/3x + 0
y = -5/3x - 5
22. perp. 1/2
y + 1 = 1/2(x + 4)
y + 1 = 1/2x + 2
y = 1/2x + 1
23. perp. 3/4
y + 5 = 3/4(x + 4)
y + 5 = 3/4x + 3
y = 3/4x - 2
24. perp. 7/5
y - 4 = 7/5(x - 5)
y - 4 = 7/5x - 7
y = 7/5x - 3
Answer:
34.29 Inch.
Step-by-step explanation:
The Aspect Ratio of a screen is the ratio of the Width to the Height of the screen.
We are told that the TV screen has an aspect ratio of 21:9
Therefore:
The height of the TV will be approximately 34.29 Inch.
The condition for an expression to be an <u>identity </u>is that both sides of equality must give the same value.
In this case, the equation that fulfills that condition is the first equation (1).
<u>Let’s prove it:</u>
1) 
Applying distributive property:
Joining together similar terms on both sides of the equality:
<h2>
>>>>>>>This is true and fulfills the condition of identity</h2>
The other equations do not fulfill the condition:
2) 
>>>>>>>This is not logic
3) 
>>>>>>>This is not logic
4) 
>>>>>>>This is not logic
