PLEASE HELP ILL GIVE BRAIN
stiv31 [10]

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

Calculate the width of a 80” TV if the TV has an aspect ratio of 21:9.
blagie [28]

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:

\dfrac{Width}{Height}=\dfrac{21}{9} \\$Since Width =80''\\\dfrac{80}{Height}=\dfrac{21}{9}\\$Cross multiply\\Height*21=80*9\\Height =(80*9) \div 21\\$Height =34.29

The height of the TV will be approximately 34.29 Inch.

Which equation is an identity?
dalvyx [7]

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) 3w+8-w=4w-2(w-4)



Applying distributive property:



3w+8-w=4w-2w+8



Joining together similar terms on both sides of the equality:



2w+2w-4w=8-8



<h2>0=0    >>>>>>>This is true and fulfills the condition of identity</h2>

The other equations do not fulfill the condition:


2) 5y+5=5y-6


5y-5y=-6-5


0 =-11   >>>>>>>This is not logic



3) 6m-6=7m+9-m


6m-7m+m=9+6


0=15  >>>>>>>This is not logic



4) 8-(6v+7)=-6v-1


8-6v-7=-6v-1


1=-1   >>>>>>>This is not logic
