I’m also still at finding answer so keep calm and I will give answer
Answer:
x = -7/5 y = -6/5
Step-by-step explanation:
System:
y = -2x-4
AND
y= 3x+3
therefore -2x-4 = 3x+3
-2x-3x = 3 + 4
-5x = 7
x = -7/5
y = 3(-7/5) + 3 = -21/5 + 3 = -6/5

Answer:
Height= 4m (nearest meter)
Step-by-step explanation:

Diameter= 2(radius)
Given that the diameter is 12m,
radius of cone
= 12 ÷2
= 6m
Let the height of the cone be h meters.



h= 4.0054 (5 s.f.)
Thus, the height of the cone is 4m. (nearest meter)
Answer:
Step-by-step explanation:
y=x²+6x+5
=(x²+6x+(6/2)²)-(6/2)²+5
=(x+3)²-9+5
=(x+3)²-4
The axis of symmetry is x+3=0
or x=-3
when x=-3,f(x)=-4
vertex is (-3,-4)
Domain :-∞<x<∞
or (-∞,∞)
Range:[-4,∞)
