Answer:
(3,4)
Step-by-step explanation:
The average speed of the plane between Austin and Dallas is 232 kmph
<u>Solution:</u>
Given that,
Total distance traveled by airplane = 290 km
Time taken for travel between Austin and Dallas = 1 hour 15 minute
Let us convert the time taken to hours

<em><u>The average speed is given as:</u></em>

Plugging in the values, we get,

Hence the average speed is 232 kmph
Answer:
a) f(x) = (-1/3)x + 8
b) f(x) = (1/3)x + 9
Step-by-step explanation:
f(x) = 1/3x - 8
a) To reflect across the x axis multiply f(x) by -1.
-f(x) = -1 (1/3x - 8)
= (-1/3)x + 8
b) to translate up 17 units add 17 to f(x)
f(x) + 17=
= 1/3x - 8 + 17
= 1/3x + 9
The area is 21
The area of a triangle is base*hight/2
Take the area of each triangle and divide them. Hope this helped!
Where did you get that A and B? I could answer if you were much more precise.
