Answer: I Think It Is Greater Than Or Equal To -9
Step-by-step explanation: The given function is:
f(x)x^2+2x-8
We complete the square to write this function in the form:
f(x)=a(x-h)^2+k
We add and subtract the square of half the coefficient of x.
f(x)=x^2+2x+1^2-1^2-8
f(x)=(x=1)^2-9
The vertex of this function is (h,k) which is (-1,-9)
The equation of axis of symmetry is x=h
But h=-1, hence the axis of symmetry isx=-1
To find the x-intercepts, we put f(x)=0
(x+1)^2-9=0
(x+1)^2=9
x+1=the square root of 9
x=-4, 2
The x-intercepts are:(
-4,0) and (2,0)
The given function is a polynomial function, the domain is all real numbers
The function has a minimum value of y=-9.
Therefore the range is y|y is greater that or less than -9
Let's see... 6% of 14.50 is 0.87. 6% of 12 is 0.72. So...
14.50 + 87 = 15.37
12 + 0.72 = 12.72
15.37 + 12.72 = 28.09
Altogether, they paid $28.09
Answer:
-52 / 5
Step-by-step explanation:
3 9/10 * -8 / 3 = 39 / 10 * -8 / 3 = -52 / 5
So u hav two numbers one is the multiple of another (so like 2 and 4) ( it can go into the other number) then the least common multiple of the other
I think an answer would be if u do 2 and 4 the LCM would be 2 (don’t know if I’m right not sure about my LCM)
