Step-by-step explanation:
f(x)=3x−2 so when the variable x is replace with an actual value ( − 1 ) we get f(−1)=3(−1)−2
=−3−2
=−5
Answer:
Step-by-step explanation:
Formula to determine the scale factor,
Scale factor =
2 =
2 =
P'Q' = 4 cm
Similarly, for the length of A'B',
2 =
2 =
A'B' = 3 cm
For the length of M'N',
2 =
2 =
M'N' = 6 cm
Answer:
Length of kitchen on blueprint = 4 in.
Step-by-step explanation:
Scale used to draw a blueprint of a house :
6 feet = 1 in.
Therefore, 1 feet = in.
If the length of kitchen = 24 feet
Then the length of kitchen on the blueprint will be
=
= 4 in.
Therefore, length of kitchen on blueprint is 4 in.
Answer:
m<BA = 180degrees
Step-by-step explanation:
First you must know that measure of <BA is 180 degrees and m<CD = m<BA
Since <CD = 16z - 12, hence;
180 = 16z - 12
16z = 180++12
16z = 192
z = 192/16
z = 12
Get <BA
m<BA = 16z - 12
m<BA = 16(12) - 12
m<BA = 192 - 12
m<BA = 180degrees
