Answer: (5, -7)
Step-by-step explanation:
On a graph, the solution(s) of two equations is/are the points at which they intersect.
For the graph shown, there is only one intersection point, (5, -7). This set of coordinates satisfies both equations, so it is a solution to the system.
The first graph is the answer. (The one with the parabola in the first quadrant)
D is the answer
because you are doing y=2(x+3)^2 - 5
First, do exponents
(x+3)(x+3) = x^2 + 6x + 9
now Multiply your answer by 2
2(x^2 +6x + 9) = 2x^2 + 12x + 18
Then, Subtract 5 from 18
2x^2 +12x + 18-5 = 2x^2 + 12x + 13
bringing you to answer D
Answer:
Possible lengths of the silk fibre 'x' are 100, 75, 60, 50 and 30 yards respectively.
Step-by-step explanation:
Let the length of the silk fiber = x yards.
Let the number of silk fibres = a.
It is given that the silk fibers between 3 to 10 yards are combined to form a silk thread of 300 yards.
So, we get the equation,
, where 
i.e. 
,
So, the possible values of 'a' are 3, 4, 5, 6 an 10.
Thus, the possible lengths of the silk fibre 'x' are 100, 75, 60, 50 and 30 yards respectively.
