Answer:
12) y=3x-15
14) y=-1/2x
16) y=13x-105
Step-by-step explanation:
Parallel lines always have the same slopes but different y-intercepts. So, we can make the equation (b is y-intercept of new equation):
12) y=3x+b
14) y=-1/2x+b
16) y=13x+b
now, we can plug in each of the coordinates given to these equations.
12) (4,-3): 4 is x, -3 is y.
-3=3(4)+b
simplify: b= -15
14) (-4,2): -4 is x, 2 is y
2=-1/2(-4)+b
simplify: b=0
16) (9,12): 9 is x, 12 is y
12=13(9)+b
simplify: b=-105
Now, plug in those numbers to your equation for b value.
12) y=3x-15
14) y=-1/2x
16) y=13x-105
*for 14 we don't need to write anything after -1/2x because b=0*
Answer:
3x3-x2-5x+3
Step-by-step explanation:
Open brackets
12 is decided by 2 and 3 so it’s not prime
Answer:
largest angle measures 108°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
8x - 6 + 108 + 14 = 180, simplify left side
8x + 116 = 180 ( subtract 116 from both sides )
8x = 64 ( divide both sides by 8 )
x = 8
Thus
∠ U = 8x - 6 = 8(8) - 6 = 64 - 6 = 58°
Then the largest angle measures 108° ( ∠ B )
Answer: 
Step-by-step explanation:
You need to analize the information given in the exercise.
In this case you know that the List price is:
And, based on the data given, you also know that the Trade discount is:
Then, the first step you need to apply is to multiply the List price by the Trade discount, as you can observe below:
Now it is important to remember that, by definition, the Net cost can be found by subtracting the List price (which in this case is $74.13) and the product of the List price and the Trade discount (which in this case is $24.71).
Then, through this procedure, you get the following Net cost:
