Answer:
(2,-17) should be the minimum.
Step-by-step explanation:
The minimum of a quadratic function occurs at
. If a is positive, the minimum value of the function is 
occurs at 
Find the value of 
x = 2
evaluate f(2).
replace the variable x with 2 in the expression.

simplify the result.



The final answer is -17
Use the x and y values to find where the minimum occurs.

Step-by-step explanation:
Let x = hours to meet
train one has a 2 hour head start or 210 km head start
210 + 105x = 135x
30x = 210
x = 7 hours to meet
Answer:
-1
Step-by-step explanation:
given f(x)=-4x+7 find f(2)
f(2) means question : if x=2, f(2)=?
f(2)= -4x2+7=-1

= 21
First, simplify

to

/ Your problem should look like:

= 21
Second, multiply both sides by 8. / Your problem should look like: -7k = 167
Third, divide both sides by -7. / Your problem should look like: k =
Fourth, simplify

to

/ Your problem should look like: k =
Fifth, simplify

to 24. / Your problem should look like: k = -24
Answer:
k = -24
