Answer:
1
Step-by-step explanation:
absolute values are always positive, so the absolute value of -1 is 1
always going to be positive
Answer:
32
Step-by-step explanation:
Answer:
Slope intercept form is y=mx+b
So y=-1/2x(m=slope which you go down one over 2 from your y-intercept)
y=-1/2x ( There would be no b because your b is 0, that's where it crosses the y axis)
Step-by-step explanation:
Answer:
angle 1 and angle 3 are congruent
Step-by-step explanation:
Angles supplementary to the same angle are congruent. Here both angles 1 and 3 are supplementary to angle 2, so angles 1 and 3 are congruent.
_____
If you like, you can get there algebraically:
m∠1 + m∠2 = 180
m∠3 + m∠2 = 180
Subtract the second equation from the first:
(m∠1 + m∠2) - (m∠3 + m∠2) = (180) - (180)
m∠1 -m∠3 = 0 . . . . simplify
m∠1 = m∠3 . . . . . . add m∠3
When angle measures are the same, the angles are congruent.
∠1 ≅ ∠3
