2x - y = 1
y = 2x -1
slope = 2
perpendicular slope = -1/2
y = mx + c
y = -1/2 + c
at point (3,2)
2 = -1/2 (3) + c
c = 2 + 3/2
c = 7/2
y = -1/2 x + 7/2
y + 1/2x = 7/2
2x - y = 1 ------------------- (1)
y + 1/2x = 7/2 -------------(2)
(1) + (2):
2x + 1/2x = 1 + 7/2
5/2 x = 9/2
5x = 9
x = 9/5 ---- sub into (1)
2x - y = 1
2(9/5) - y = 1
18/5 - y = 1
y = 18/5 - 1
y = 13/5
Ans: x = 9/5, y = 13/5
Answer:
Its not a function, D
Step-by-step explanation:
its not a function because the x value, 1, repeats. input is x and output is y, so the input of 1 has more than one output.
N is less than or equal to 6 n<_ 6 the arrow thingy is supposed to be on the line
The given is: <span>−2(x+1)≥3x+8
The first step is getting rid of the brackets using the distributive property.
The second and third steps is isolating the term containing the x on one side of the inequality using addition or subtraction property of order
The last step is getting rid of the coefficient of the x using the multiplication or division property of order.
So, the correct order of choices is:
1- </span>distributive property.
2- addition or subtraction property of order
3- addition or subtraction property of order
4- multiplication or division property of order.<span>
