64 ÷ 8 = 8
Answer:
The solution is the point where the lines intersect.
The answer is (-3 , -8)
Answer:
Vertex: (- 2, -1)
axis of symmetry: x= - 2
Step-by-step explanation:
f(x)=x^2+4x+3
f(x)=(x^2+4x+4)+3-4.......complete the square
f(x)=(x+2)^2-1...................write in vertex form
Answer:
C) 50
Step-by-step explanation:
This is because -10 x 5 = -50 and if you have 20 points to start with, you just do 20-(-30)=20 and two minuses make a plus so it is 20 + 30 which is 50.
