Which equation represents y = −x2 + 6x + 7 in vertex form? y = −(x + 3)2 + 4 y = −(x − 3)2 + 10 y = −(x + 3)2 + 2 y = −(x − 3)2

Colt1911 [192]

$\text{The vertex form:}\ y=a(x-h)^2+k\\\\f(x)=ax^2+bx+c\to h=\dfrac{-b}{2a},\ k=f(h)\\\\\text{We have}\ y=-x^2+6x+7\to f(x)=-x^2+6x+7\\\\a=-1,\ b=6,\ c=7\\\\h=\dfrac{-6}{2(-1)}=\dfrac{-6}{-2}=3\\\\k=f(3)=-3^2+6(3)+7=-9+18+7=16\\\\Answer:\ \boxed{y=-(x-3)^2+16}$

5x + 2y = 3 2x+3y=-1 Solve

professor190 [17]

Answer:

x = 1

y = -1

Point = (1,-1)

Step-by-step explanation:

2x + 3y = -1 = y = -2/3 - 1/3

5x + 2(-2/3 - 1/3) = 3

5x - 1 1/3 - 2/3 = 3

5x - 2 = 3

+2 +2

5x = 5

x = 1

2(1) + 3y = -1

2 + 3y = -1

-2 -2

3y = -3

y = -1
