Answer:

y = -x - 4

Step-by-step explanation:

the equation of a linear graph is y = mx + b

you know the m = -1

so now the equation is y = -x + b

from here, what you could do to find b is...

plug (-1, -3) into the equation

1) x = -1, y = -3

2) -3 = -(-1)  + b

3) -3 = 1 + b

4) -4 = b

or you can look at the y-intercept which is where the line intersects with the y-axis

it seems to be (0, -4)

so "b" would be equal to -4

this makes the final equation y = -x + (-4) or y = -x - 4

The graph is falling on the left hand side and rising on the right hand side.

Since the two ends of graph are in opposite direction, the exponent of variable has to be odd. For an even exponent of leading term, the two ends are in same direction.

Since the graph is falling on left and rising on right, this indicates that the coefficient of leading term is positive.

So, the leading term must have:
1) Odd exponent
2) Positive Coefficient

Thus, option Fourth is the correct answer

sveta [45]

Answer:

42 candles

Step-by-step explanation:

Firstly, we need to find the surface area of the pyramid used. This can be obtained by finding the area of the base, multiplied by the height of the pyramid.

The area of the base since it is rectangle is L * B and that is 5 * 2 = 10cm.sqr

The volume of the pyramid is A * h and that is 10 * 12 = 120cm.cub

To fInd the number of candles used , we simply divide the volume of wax by the volume of a candle.

That is 5040/120 = 42 candles
