Answer:
y = 1/2x + 4
Step-by-step explanation:
Lines that are parallel have the same gradient....in which its 1/2
Equation of the line that is parallel to y = 1/2x + 5 and passes through (-4,2)
(y - 2) = 1/2(x + 4)
2(y - 2) = x + 4
; 2y - 4 = x + 4
Equation of the line,
y = 1/2x + 4
Answer:
-3
Step-by-step explanation:
You might find it easier to write -(11 - 8), which is -(3), or -3.

Step-by-step explanation:
Answer:
14 and 6
Step-by-step explanation:
Let's start by naming the first number x.
We can name the second number y.
We can set up equations to model our situation.
x+y=2x-8
x-y=2y-4
Let's simplify the equations.
x+y=2x-8
Subtract 2x from both sides
-x+y=-8
__________
x-y=2y-4
Subtract 2y from both sides.
x-3y=-4
Add the two equations together to eliminate x.
x-3y=-4
-x+y=-8
________
0x-2y=-12
-2y=-12
Divide both sides by -2.
y=6
The second number is 6.
Plug that back in.
x+6=2x-8
Subtract x from both sides
6=x-8
Add 8 to both sides
x=14
The first number is 14
True.
The range for arctan is all the valid Y-Values, and if you take a look at the graph you can see it caps out at pi/2 and -pi/2 for y values.
P.S. pi/2 = 1.57......
