Answer:
x = (k-14)/5
Step-by-step explanation:
5x + 14 = k
Subtract 14 from each side
5x + 14-14 = k-14
5x = k-14
Divide by 5
5x/5 = (k-14)/5
x = (k-14)/5
Answer:
15 units²
Step-by-step explanation:
Hi there!
where <em>b</em> is the base and <em>h</em> is the height
Plug in the base (7.5) and height (4):
Therefore, the area of the triangle is 15 units².
I hope this helps!
First we need to find f(2) and f(5), which are 5 and 11 respectively; all you have to do is plug in 2 and 5.
Then, we use the following formula:
(f(b)-f(a))/(b-a),
where b and a are the largest and smallest x values respectively.
Finally, we plug our values in:
(11-5)/(5-2)=6/3=2
In fact, the average rate of change of any linear function is just the coefficient of the x term. Hope this helped!
Answer:
(-x,y)
Step-by-step explanation:
The x coordinate changes while the y stays the same when reflected across the x axis.
