Help, please? Choose the best graph that represents the linear equation: y + 3 = 0

Mathematics

Nookie1986 [14]4 years ago
7 0

Answer:

The answer is group C

Step-by-step explanation:

The graph of group C depicts a typical and perfect presentation of the linear equation y+3=0

Simplifying the above equation thus:

y + 3 = 0

Make y subject of formula by subtracting 3 from both sides. Thus,

y + 3 - 3 = 0 - 3

y =  -  3

Therefore, we draw a straight line across -3 on y axis. Hence, group C linear graph.

The cake density is 0.454 ounce per cubic inch and the fair price is $0.20 per ounce. What should be a fair price for each cake?
aleksklad [387]

Answer:

price = x * 0.2

or

price = x * 0.454 * 0.2

Step-by-step explanation:

In this case we must know either the mass of the cake or its volume.

Given the case that we know the mass of the cake, it would be:

price = x * 0.2

where x is the mass of the cake in ounces, that is to say if for example a cake has a mass of 10 ounces, it would be:

price = 10 * 0.2 = 2

which means that each cake costs $ 2

Given the case of the volume, we must first multiply the density by this volume in order to calculate the mass and finally the price.

price = x * 0.454 * 0.2

where x is the volume of the cake in cubic inches, if for example the volume is 10 cubic inches it would be:

price = 10 * 0.454 * 0.2 = 0.908

which means that each cake costs $ 0.9

A pyramid has a base area of 124 in² and a height of 25.2 in. What is the volume of the pyramid?
xeze [42]

Answer:

1041.6

Step-by-step explanation:

The volume of a pyramid is V=b x h x 1/3 . b is the area of the base and h is the height. V=124 x 25.2 x 1/3 This can simplify to V=3124.8 x 1/3 . You could also just divide by 3. You will get 1041.6
