ANSWER
It is horizontally compressed by a factor of 2 and reflected over the y-axis.
EXPLANATION
The parent function given to us is
The parent function has been transformed to obtain
This transformation is of the form:
If
then,there is a horizontal compression by a factor of k.
Hence
is horizontally compressed by a factor of 2.
Since -2<0, it is a reflection in the y-axis.
The correct choice is the last option.
Multiply 125.5 miles by 1.61 to get total kilometers:
125.5 x 1.61 = 202.055 kilometers total.
Divide 150 minutes by 60 to get total hours:
150/ 60 = 2.5 hours.
Now Divide total kilometers by total hours to get kilometers per hour:
202.055 kilometers / 2.5 hours = 80.822 kilometers per hour.
Round the answer as needed.
You would write it out as:
14 > x
or
x < 14
2(2x +4y) +(3x -y) = 2(10) +(8)
.. 7x +7y = 28
Marla has incorrectly calculated the constant as 12. It should be 28.
Answer:
m<A = 30degrees
m<B = 70degrees
Step-by-step explanation:
Find the diagram attached
From the diagram;
m<A + 150 = 180
m<A = 180 - 150
m<A = 30degrees
Also since the sum of angles in a triangle is 180degrees, hence;
m<B+m<A + 80 = 180
m<B+30+80 = 180
m<B+110 = 180
m<B = 180 - 110
m<B = 70degrees
