Answer: D. 453 miles .

Step-by-step explanation:

Given: The function d(t)=458-60t models the distance, in miles, that Jessica is from her house <em>t </em>hours after she began returning home.

At t = 5 minutes = \dfrac{5}{60} hour     [1 hour = 60 minutes],

Distance covered by Jessica in 5 minutes = d(\dfrac{5}{60})=458-60(\dfrac{5}{60})

=458-5=453\ miles

Jessica is 453 miles from her home after 5 minutes she began returning home.

Hence, the correct option is D. 453 miles .

X<br> f(x) = 2x-1 -2 <br><br> Please help

By evaluating the linear equation, we can complete the table:

x: -2 | -1 | 0 | 1 | 2 |

y: -3 | -1 |  1 | 3 | 5  |

<h3>How to complete the given table?</h3>

Here we want to complete the table:

x: -2 | -1 | 0 | 1 | 2 |

y:     |    |    |    |    |

To get the correspondent values in the "y" row, you just need to evaluate the linear function in the given values of x.

Here the function is:

f(x) = 2x - 1

Evaluating it we get:

f(-2) = 2*(-2) + 1 = -3

f(-1) = 2*(-1) + 1 = -1

f(0) = 2*0 + 1 = 1

f(1) = 2*1 + 1 = 3

f(2) = 2*2 + 1 = 5

Now we just put these values in their correspondent place on the table.

x: -2 | -1 | 0 | 1 | 2 |

y: -3 | -1 |  1 | 3 | 5  |
