Answer:
rationalizing
Step-by-step explanation:
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....
F(x)/g(x) = (2x +3)(x -1)/(x -1) = 2x +3 . . . . . x ≠ 1
The domain of (f/g)(x) is all real numbers except 1.
_____
The domain of any rational function necessarilly excludes any values that make the function undefined, that is, that make the denominator zero.
Answer:
X=15
Step-by-step explanation:
Ignore the increase for equasion. This is factored in but irellevent. Orignal x value is 13, but increases to 15, and orignal x value is not needed for this equasion. (its there to confuse you)
L+L+W+W=66.
(w+3) +(w+3) +w +w = 66
(4xw) + 3 +3= 66
4 x w = 66 -3 -3
4 x w =60
60/4= 15.
L= 15+ 3 =18
W = 15.
W + W + L + L
15 + 15 + 18 +18 =66
Answer:
Step-by-step explanation:
Standard form: Ax+By=C
Change C to 53
Ax+By=53
He could have added a combination of $1 bills and $5 bills or just $1 bills.
I hope this is right
