Answer:
109
Step-by-step explanation:
81-19 is 62. if you add 109 then you could do 109-19 is 90
Answer: B is what 6 x +4 = to 4bx - 2 is 6x plus 4 = to 24 then 4bx - 2 is YA so b is Y
Parent function = √x
On stretching vertically by factor of 6
New function G(x) = 6√x
I think the answer is d or b if im wrong sorry hope this helped tho :p
<span>2x+y=400
A=xy area of farmland
y=400-2x
A=400x-2x^2
A'(x)= 400 -4x derivative of area with respect to x
0=400-4x find out where f ' equals 0
4x=400
x=100
A'(x)= 400 -4x
A''(x)= -4 check 2nd derivative. if negative then relative max at x=100
2x+y=400
y=200
dimensions 100x200
hope it helped</span>
