What is the value of x if a rectangle has a perimeter of 50, a length of x + 5, and width of 11?
Paraphin [41]

Answer:

x = 9

Step-by-step explanation:

Perimeter = 2 * width + 2 * length

= 2*11 + 2(x + 5) = 50

2x + 10 + 22 = 50

2x = 50 - 10 - 22

2x = 18

x = 9

Which is an equivalent form of the expression 1800(1.2)^-t
ololo11 [35]

Answer:

1800(5/6)^t

Step-by-step explanation:

I don't see any answer choices, but this would be another form if it is listed. The negative exponent means that you get the reciprocal of the fraction (in this case 1.2). This turns 1.2 into (1/1.2), which is equivalent to 5/6.

X<br> f(x) = 2x-1 -2 <br><br> Please help
Kobotan [32]

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  |
