So to find the x vertex u have to apply the formula x= -b/2a so it will be
x= -(-4)/2(1)
x= 4/2
x= 2
and to find the y vertex u just substitute the x value into the original equation so it will be
y= (2)^2-4(2)+1
y= 4-8+1
y= -3
so the coordinates of the vertex are (2,-3)
Answer:
1,100 is the answer.
Step-by-step explanation:
Since the difference of the subtraction problem is 1,103, when it is rounded, it becomes 1,100.
Answer:
A.1
Step-by-step explanation:
looking at the function, you can see that you should use the second equation, x^3-9x^2+27x-25, x>=2
step 1: insert 2 into the equation. (2)^3-9(2)^2+27(2)-25
step 2: simplify equation 8-36+54-25=1
Answer:
7/10
Step-by-step explanation:
2/5 turns into 4/10
4/10 plus 3/10 is 7/10
