Answer:
Step-by-step explanation:
Answer:
P (−11, 13), Q (−17, −19), R (23, 27)
Step-by-step explanation:
we know that
The reflection of a figure across the x-axis has the following rule
(x,y) -----> (x,-y)
so
P(-11,-13) -----> P(-11,13)
Q(-17,19) -----> Q(-17,-19)
R(23,-27) ----> R(23,27)
Answer:
135 degrees
Step-by-step explanation:
Octagons have 8 sides which make up 8 angles that are all equal to each other.
The angles must sum up to 1080 degrees in an octagon.
Take 1080 degrees and divide by 8 angles and you will get 135 degrees.
Density = mass / volume
Givens
Density = 13.6 grams / cm^3
mass = 47 grams.
Solve
D = m/v
13.6 = 47 / volume Multiply by volume
13.6 * volume = 47 Divide by 13.6
volume = 47 / 13.6
Volume = 3.46 ccs
First convert -5/6(b+1) to -5/6b-5/6 which looks like:
1/3b+2/3b-5/6b-5/6
second add 1/3b+2/3b=3/3b, convert to 6/6b so:
6/6b-5/6b-5/6
subtract 6/6b-5/6b = 1/6b so:
1/6b-5/6 is the answer
