Step-by-step explanation:
Area=(a+b)/2 x h
a=6x+3
b=4x-5
h=-5x+10
Area= -25x^2+55x-10
The average speed of Joshua during that time is 2500 m/h.
Explanation:
It is given that Joshua started cycling at 5:15 pm. By 8:09 pm he has covered a distance of 7250 m.
The total time taken by Joshua from 5:15 pm to 8:09 pm is

Dividing we get,

Adding, we have,

Thus, the total time taken by Joshua is 
To determine the average speed we use the formula,

where
and 
Hence, substituting the values we have,

Dividing, we get,

Thus, the average speed of Joshua during that time is 2500 m/h.
Answer:
march 9
Step-by-step explanation:

=9
I think that's the answer
Answer:
0
Step-by-step explanation:
Put -6 where x is and do the arithmetic.
f(-6) = 1/3 (-6 +6) = 1/3 (0)
f(-6) = 0
Answer:
2
Step-by-step explanation:
f(x) = 2x - 3 is a linear function
The rate of change of a linear function is the measure of the slope.
The equation is in slope- intercept form, that is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 3 has slope m = 2
Thus rate of change = 2
