A shop sells newspapers for a profit of 0.5%. His sales for the month of January were $8341.50. How much of this is profit?

The straightline through the points (0, -1) and (-1, 1), represents the equation f(x) = -2x - 1. The correct option is D.

What is an equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

For the equation f(x) = -2x - 1, we can see that the slope (m) is -2, and the y-intercept (b) is -1.

To graph this line, we can plot the y-intercept first, which is the point (0, -1) on the y-axis. Then, using the slope of -2, we can find another point on the line by moving 2 units up and 1 unit to the left, which gives us the point (-1, 1). We can continue this process to plot more points on the line, but two points are enough to draw a straightline.

So, we can draw a straight line through the points (0, -1) and (-1, 1), which represent the equation f(x) = -2x - 1.

#SPJ2

Answer:

Step-by-step explanation:

Set this up as a proportion with oz on the top and grams on the bottom and then fill in with what you are given:

Cross multiply to get x = 28*3 so x = 84 g

Do the same for the next ratio:

and cross multiply again to get

28x = 140 so

x = 5 oz

Answer:

Ounces                Grams

     1                         28

      3                        84

       5                        140

Step-by-step explanation:

Since one ounce is 28 grams you would do 3 times 28 which gives you 84 and so 3 ounces if equal to 84 grams. Now we have to find how many ounces in 140 grams. We would do 140 divided by 28 which gives us 5 and so 140 grams is equal to 5 ounces. Hope this helps! If not well...

Step-by-step explanation:

Sure! I can help you with that. To graph the inequality y ≤ -2 or y > 1, we will need to create two separate graphs and then combine them.

First, let's graph the inequality y ≤ -2. This represents all the values of y that are less than or equal to -2. We can represent this on a number line or a coordinate plane.

To graph y ≤ -2, we draw a horizontal solid line at y = -2 and shade everything below the line. This includes all the points on the line as well. It would look like this:

                        |

                        |

                        |

                        |

                        X------------ (y = -2)

                        |

                        |

                        |

                        |

Next, let's graph the inequality y > 1. This represents all the values of y that are greater than 1.

To graph y > 1, we draw a horizontal dashed line at y = 1 and shade everything above the line. This does not include any points on the line itself. It would look like this:

                        |

                        |

                        |

                        |

                        X------------ (y = -2)

                         ------------

                        |

                        |

Now, to combine the two graphs, we shade the area that satisfies both inequalities. In this case, that would be everything above the line y = -2 and everything above the line y = 1. The shaded area would be above y = 1 because it satisfies the condition y > 1.

The final graph would look like this:

                        |

                        |

                        |

                        |

                         ------------

                        |           |

                        |           |

                        |           |

                        |

This graph represents the solution to the inequality y ≤ -2 or y > 1.
