Answer:
No minimum.
Step-by-step explanation:
The equation of the parabola is given to be y = - x² - 6x - 7 ......... (1)
Now, rearranging the equation we get
y = - (x² + 6x + 9) - 7 + 9
⇒ y = - (x + 3)² + 2
⇒ y - 2 = - (x + 3)²
⇒ (x + 3)² = - (y - 2) ........ (2)
Now, this equation is similar to the parabola equation (x - α)² = - 4a(y - β), which is the vertex form of a parabola equation.
Therefore, we can say that equation (2) has the vertex at (-3,2) and the axis is parallel to the negative y-axis.
Therefore, the parabola (1) has a maximum at (-3,2) and it does not have a valid minimum. (Answer)

Answer:
(3,-2)
Step-by-step explanation:
Given equations of line
3x-2y=13
2y+x+1=0
=> x = -1 -2y
Point of intersection will coordinates where both equation have same value of (x,y)
top get that we have to solve the both equations by using method of substitution of simultaneous equation.
using this value of x in 3x-2y=13, we have
3(-1-2y) -2y = 13
=> -3 -6y-2y = 13
=> -8y = 13+3 = 16
=> y = 16/-8 = -2
x = -1 - 2y = -1 -2(-2) = -1+4= 3
Thus, point of intersection of line is (3,-2)
