Hey there. The answer is A. 4/11.
To find the slope, look at the coordinates (-7, 2). Starting from there, we need to find the slope to go to the point (4, 6). We need to find the rise over run.
Look at the picture I attached. I hope you understand and find my answer helpful.
Answer:
B.y=-2(x+3)2-2
Step-by-step explanation:
A if false beacuse you have to put (-3,-2) into all of your equations
B is correct
C is false
D is also false
Answer:
∠C ∠D
82° 98°
132° 48°
115° 65°
25° 155°
Step-by-step explanation:
180 -82 = 98
180 - 132 = 48
180 - 115 = 65
180 - 25 = 155
Answer:
(-1,-4)
Step-by-step explanation:
The equation of a parabola os written as: ax^2+bx+c
This parabola's equation is x^2+2x-3
● a= 1
● b= 2
● c = -3
The coordinates of the parabola are: ( (-b/2a) ; f(-b/2a) )
● -b/2a = -2/2 = -1
● f(-b/2a) = (-1)^2+2×(-1)-3=1-2-3= -4
So the vertex coordinates are (-1,-4)
