Answer:
x = -6
Step-by-step explanation:
A plot of the points tells you one is above the other on the same vertical line. The equation for a vertical line is ...
x = constant
In order for the line to go through points that have x-coordinates of -6, the constant must be -6. The equation of the line is ...
x = -6
You solve an equation like this by adding the opposite of the constant to both sides of the equation.
... V -16 +16 = -32 +16 . . . . . addition property of equality: if a=c, then a+b = c+b
... V + 0 = -16 . . . . . . . . . . . . additive inverse property of integers: -16+16 = 0
... V = -16 . . . . . . . . . . . . . . . identity element of addition: V+0 = V
_____
<em>You can always do the same thing to both sides of an equation.</em> Here, it is useful to add the opposite of -16 to both sides. That way the constant on the left becomes zero, so you only have the variable by itself—which is what you want.
Answer:
1 
Step-by-step explanation:
5/3 = 3/3 * 2/3
3/3 = 1
So the answer is 1
Answer:
c = 5 cm
Step-by-step explanation:
Use Pythagorean Theorem
3^2 + 4^2 = x^2
9 + 16 = x^2
25 = x^2
x = 5
