Which system is equivalent to y= 9x^2 x+y=5 ?

melomori [17]

Answer : Option A

Explanation:

we can clearly see that from x+ y=5 we can substitute y = 5-x in y = 9x^2

Option B is clearly incorrect x can not be y -5

Option C is incorrect because y can not be 5 +x

Option D is incorrect because its y = 9x^2 not y^2 =9x^2 so y can not be 3x

if its y^2 = 9x^2 then only implies y = 3x

BRAINLIESTT ASAP! PLEASE HELP ME :)

Step-by-step explanation:

$\displaystyle y = Acos(Bx - C) + D$

According to this trigonometric function, −C gives you the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL:

$\displaystyle Phase\:[Horisontal]\:Shift → \frac{-\frac{2}{3}π}{2} = -\frac{π}{3} \\ Period → \frac{2}{2}π = π$

Therefore we have our answer.

Extended Information on the trigonometric function

$\displaystyle Vertical\:Shift → D \\ Phase\:[Horisontal]\:Shift → \frac{C}{B} \\ Period → \frac{2}{B}π \\ Amplitude → |A|$

NOTE: Sometimes, your vertical shift might tell you to shift your graph below or above the midline where the amplitude is.

I am joyous to assist you anytime.
