Answer:
A
Step-by-step explanation:
By doing the unit rate, dividing 19 on both the top and bottom, getting this 8.36.../1, you can just round it to 8/1, meaning he makes about 8 deliveries per hour. Hope this helps!
Translations to the left and right take the form f(x-s), where s is the value of the shift. Note that shifts in the positive (right) direction appear negative, and shifts in the negative (left) direction appear positive. It's common to mistake these, so memorize the rule! In this case, the shift becomes f(x-4) = -3(x-4). A vertical stretch takes the form of k*f(x), where k is the value of the stretch. This stretch would appear as 4*f(x) = 4(-3x). Combining these transformations would yeild 4*f(x-4) = 4[-3(x-4)]. Simplify for the final result.
Answer:
C.
Step-by-step explanation:
interior angles for ABCD is 360° and for ABO(triangle above) is 180°
from triangle,
you will get angle for OBA which is 180° - 38° - 90° = 52°
from angle B, we know that, straight line is 180°.
so,
180° = 52° +y- 12°
y = 140°
so, we can calculate x.
360° = 90° + 90° + 128° + x
x = 52°
Line <em>m</em> and <em>l</em> are parallel, so the angle will be the exact same for both.
x = 30, since 30+25=55. You could also do 55-25=30.
