Change the function into vertex form:
f(x)=x²-10x+16
make a square by (adding half of -10)², which is 25, then subtract it:
f(x)=x²-10x+25-25+16
f(x)=(x-5)²-9
so the vertex is at (5,-9)
another way to do it:
f(x)=x²-10x+16
the vertex is when x=-
, b=-10, a=1 in this case.
x=-(-10/2*1)=5
plug x=5 into the quadratic function, you get f(x)=-9
Answer: r + 4
Step-by-step explanation:
If you want to see if they are equivalent just substitute any number such as 2, so 2.5(2) = 5 and 2 + 5 = 7, so they are not equivalent (THIS IS TRUE UNLESS YOU DIDNT PUT THE X VALUE IN THE QUESTION)
There are 10 coins in total, and 2 of which are quarters. so our fraction form is 2/10, which we can reduce down to 1/5
Answer:
<em>n= Total number of packages on trucks= 6096</em>
<em>n = T x P (Model Equation)</em>
Step-by-step explanation:
No. Of delivery trucks = T = 127
Package on each truck = P = 48
Total number of packages on trucks =n= ?
Each truck contains 48 packages and total trucks were 127, to find total number of packages on trucks , we just need to multiply the number of trucks with the number of package on each truck.
Total number of packages on trucks =n= (No. Of delivery trucks) x (Package on each truck)
n = T x P (Model Equation)
n= 127 x 48
n= 6096 (Total number of packages on trucks)
