Answer:

You can draw a graph.

  (-3,2)                     |

            (-2,1)            |          

      ___.__(-1,0)__ | __.____.___

                                |     (1,-1)

                                |

                                |

As shown, the lines are intersecting. You can also tell that they are intersecting because if you draw a triangle, they are on the same line. (-3,2) and (-2,1) are directly diagonally from each other.

Hope this helps!

Answer:

y=-3x+4

Step-by-step explanation:

The question is asking for the equation in slope-intercept form. This is y=mx+b where m is the slope and b is the y-intercept.

The slope can be found by counting the units in between two points on the graph. Remember that slope is rise over run or y/x. Two points on the graph are (2,-2) and (1,1). The y is increasing by 3 while x is decreasing by 1. This means the slope is -3.

The y-intercept is where the line intersects with the y-axis. In this case, that point is (0,4). Therefore, b=4.

The final answer is y=-3x+4.

The Skittles jar has a radius of 3.5 cm and a height of 11.5 cm. Using the two given boxes for reference what would be a good es
nevsk [136]

Answer:

1052

Step-by-step explanation:

The two given boxes for reference are presented below.

Since we know the dimensions of the first container, we can calculate its volume.

V_1= 5 \text{cm} \cdot 4 \text{cm} \cdot 4 \text{cm} = 80 \text{cm}^3

The first container held 192 skittles. Using that fact, now that we know the volume of the first box, we can calculate the volume of a single skittle.

v = \frac{80}{192} = 0.416 \approx 0.42 \text{cm}^3

The second container held 258 skittles.

The volume of the second box is:

V_2 = 12 \text{cm}\cdot 3 \text{cm} \cdot 3 \text{cm} = 108 \text{cm}^3

Using this facts, the volume of a single skittle would be

v = \frac{108}{258} = 0.418 \approx 0.42 \text{cm}^3

Therefore,  the volume of  single skittle is around to 0.42 cm³.

A skittle jar is a cylinder. Its volume is calculated by the formula

V = r^2h \pi,

where r is the radius and h is the height. From the given data, we have r = 3.15 \text{cm} and h = 11.5 \text{cm}. Hence, the volume of the jar is

V = 3.5^2 \cdot 11.5 \cdot 3.14 = 442 \text{cm}^3

Now, we can determine the number of skittles in the jar. Let n be the number of skittles in the jar. Then,

n = \frac{\text{volume of the jar}}{\text{volume of a skittle}} = \frac{V}{v} = \frac{442}{0.42} = 1052.38 \approx 1052\\
