12x-6>14x-2 graph it

Answers

Answer: 12x-6=14x-2

We move all terms to the left:

12x-6-(14x-2)=0

We get rid of parentheses

12x-14x+2-6=0

We add all the numbers together, and all the variables

-2x-4=0

We move all terms containing x to the left, all other terms to the right

-2x=4

x=4/-2

x=-2

Step-by-step explanation:

I think it maybe is 12x-6=14x-2

Answer:

Option D

Step-by-step explanation:

i) x° = 35° [Since Vertically Opposite Angles]

ii) y° + y° + 35° = 180° [Straight line ]

=> 2y° = 180° - 35°

=> 2y° = 145°

[tex] = > y = \frac{145}{2} [/tex]

=> y° = 72.5°

Answers

Answer:

Step-by-step explanation:

a) 90 degrees - lines that are tangent to a circle form right angles

b) 67 degrees - triangles have an area of 180 degrees. Since point p is tangent it is 90 so you would do x+23+90 =180 and solve (23 being the given angle).

c) 43 degrees - similarily to question b) point p is tangent and triangles are a sum of 180 degrees you would do x+47+90 = 180 and solve
