Step-by-step explanation:
m=-2
m^2+9m+3
substitute-2 in m
-2^2+9(-2)+3
= -19
Answer:
320 miles
Step-by-step explanation:
c=178
subtract the base fee of 50 from c- you get 128
Divide 128 by the 0.40 rate to get m by itself
m then equals 320
This is true
Think of two houses. If we say "the houses are identical" then the corresponding pieces must be the same (eg: the doors must be the same type out of the same material). In this analogy, the houses are the triangles, which are the overall structures. The doors are the angles since they are pieces of the overall structures. This is what CPCTC is saying
CPCTC = Corresponding Parts of Congruent Triangles are Congruent
Once again, the final answer is true.
Answer:
Use the inflection points to set up intervals. Substitute a value into each interval to find where the curve is concave up or down.
The graph is concave up
