Answer:
x ≥ 1/2
Step-by-step explanation:
6x + 21 ≥ 24
6x ≥ 3
x ≥ 1/2
check: (1/2 x 6) + 21 = 24
Answer do we just answer the question or we also have to do something else?
Step-by-step explanation:
Assuming:
Assuming you mean sets, as in "1 brick" meaning £120 worth of bricks.
--------------------------------------------------------------------------------------------------------------
Summarizing:
£12,000 for bricks.
£600 for plasterboard.
£8,000 for bolts.
--------------------------------------------------------------------------------------------------------------
Total:
£20,600
I think it is A)53 because the are the same size
i)
Axis of symmetry:
x = - 2 (the value of x vertex)
ii)
Vertex:
The vertex of a parabola is the point where the parabola crosses its axis of symmetry.
The vertex (-2, -4)
iii)
Domain:
All real number
iv)
Range: y >= - 4 (the vertex is the lowest point on the graph, it has minimum value and opens up)
