The answer is A. Because greater than or equal to > with line under represents a filled in dot. And > by itself represents an empty dot
8 times 2 equals 16 so the answer would be 16
Hello!
The answer for #1. is 4 centimeters, because it is the only reasonable answer.
The answer for #2. is 1 millimeter, because the tick is smaller than the penny, which is smaller than any of the other lengths.
I hope this helped :))
Answer:
The correct option is:
h = 1, k = 16
Step-by-step explanation:
y=4x^2-8x+20 =0
It is a quadratic formula in standard form:
ax^2+bx+c
where a = 4 , b = -8 and c=20
The vertex form is:
a(x − h)2 + k = 0
h is the axis of symmetry and (h,k) is the vertex.
Calculate h according to the following formula:
h = -b/2a
h= -(-8)/2(4)
h = 8/8
h = 1
Substitute k for y and insert the value of h for x in the standard form:
ax^2+bx+c
k = 4(1)^2+(-8)(1)+20
k = 4-8+20
k=-4+20
k = 16
Thus the correct option is h=1, k=16....
Yes it does equal since they are equivalent!
