Answer:</h3>
That would be -6.

Step-by-Step Thingy:</h3>
Adding a negative number is basically just subtracting a number, using that...
-4+(-2) ---> -4-2
Now all that's needed is to minus 2 from -4.
-4-2 ---> -6
Hope that helps, :)
Answer: y=7x-5
Step-by-step explanation:
(0,-5) (1,2)
y=kx+b
<span>x+4y=21
4x-y=16
Isolate one of the variables
x + 4y = 21
subtract 4y from both sides
x = -4y + 21
Plug that into the other equation
4x - y = 16
4(-4y + 21) - y = 16
-16y + 84 - y = 16
combine like terms
-17y + 84 = 16
subtract 84 from both sides
-17y = -68
divide both sides by -17
y = 4
Plug that into the equation
</span><span>x+4y=21
x + 4(4) = 21
x + 16 = 21
subtract 16 from both sides
x = 5

The linear equation in slope intercept form: y = mx + b.
We have:
This is not a linear equation.
A=32, B=32, C=148, D=148
A parallelogram has 2 sets of equal angles and the total sum of all angles is equal to 360
Angles A,B are 32, to work out CD add angles AB then subtract that from 360
=360-64
=296
To work out each angle (CB) divide that by 2, therefore C and D are 148
