It is okay to take the inverse of both side given that you remember to exclude the value that make the denominator zero which is in this case r=-1
Answer:
-76
Step-by-step explanation:
A positive digit multiplied by a negative digit will result as a negative digit.
So,
6 · -8 = -48
Now if there is a problem where a number is added by a negative digit number, you turn the "plus" sign into a "negative" sign.
So,
- 48 + (- 28)
-48 - 28
If you subtract a negative by a negative, the answer will be negative BUT you have to ADD those two negative digits together and put the negative sign after.
- 48 - 28 = -76
Answer:
SAS means "Side, Angle, Side"
ASA means "Angle , Side, Angle"
AAS means "Angle, Angle, Side"
HL stangs for "Hypotenuse, Length"
Step-by-step explanation:
SAS is when we have two sides meeting and forming an angle between them.
ASA is when we know two angles and a side between the angles.
AAS is when we know two angles and a side which is not between the angles.
HL means that: two triangles are congruent if the hypotenuse of one triangle is equal to the hypotenuse of the other and if one leg of a triangle is equal to a leg of another triangle.

Answer:
-3
Step-by-step explanation:
slope (m) = (y2 - y1)/(x2 - x1)
(1, 1) --> 1 = x1, 1 = y1
(2, -2) --> 2 = x2, -2 = y2
(-2 - 1) / (2 - 1) = -3 / 1 = -3
therefore, the slope is -3
