Y=2x-6 (4, 3)
(X, Y)
3=2(4)+b
3=8+b
-5=b
Y=2x-5
Answer:Thus, (-3)-4 = 1/(-3)4.
Step-by-step explanation:
Negative exponents have the following property: n-m = 1/nm OR 1/n-m = nm
So for (-3)-4 , n= -3 and -m= -4 (or m= 4).
Thus, (-3)-4 = 1/(-3)4.
Answer:
Option 4 is your answer.
Step-by-step explanation:
Answer: x=9
Step-by-step explanation:
The bottom triangle that has a 40° is an isosceles triangle, therefore the other angle at the bottom right is also 40°. This leaves the top angle to be 100°.
180=40+40+x
180=80+x
x=100
Now, to find ∠2, you can tell it is a supplementary angle. Therefore, the 2 angles add up to 180°
180-100=∠2
80°=∠2
The problem states that ∠2 is 9x-1. We know that ∠2 is 80°. We can solve for x.
80=9x-1
81=9x
x=9
