Answer:

1 and -1

Step-by-step explanation:

Factoringfind a number set that equals zero and when multiplyed, becomes -1.

1 and -1 multiply to -1 and equal 0,

so x^2-1 turns into (x+1)(x-1)

solve for both x+1=0 and x-1=0

x+1=0

x=-1

x-1=0

x=1

Answer:

40%

Step-by-step explanation:

Her monthly paycheck was 120 dollars, because thats how much she earned that month. If she saved 48 dollars, then the percentage of the paycheck she saved is the percent of 120 that is 48 dollars, or 48/120. Simplifying, we have 2/5, (because you can divide both the top and the bottom by 24), and 2/5 is equal to 40%

Which two theorems would justify that m∠4 = m∠6, given that m∠5 = m∠6 in the diagram below?
My name is Ann [436]

Answer: D) vertical angles theorem, alternate interior angles theorem

Angle 5 = Angle 6 by the alternate interior angles theorem

Angle 5 = angle 4 by the vertical angles theorem

By the transitive property, we can then say angle 4 = angle 6. These angles are also corresponding angles.

We won't use the angle addition theorem or the right angles theorem.
