The sum of 5 times a number and 16 is 31.<br> What is the number? <br> Enter your answer in the box.

agasfer [191]

Answer:

I will do a step by step explanation to help you.

First, subtract 16 from 31 so you can simplify what you need to find. We will call the unknown number X. So 5x = 15

15/5 = 3 so X = 3

Lets plug in X

3 x 5 + 16 = 31

Makes sense!

Hope this helps

Select the correct answer. What is the range of the function f(x) = -4\x+ 11 - 5? A. (-4,-5) B. [-5,-) OC. (-4,-) OD. (-2,-4] Re

Y_Kistochka [10]

We are given the following function:

$f(x)=-4\lvert x+1\rvert-5$

This function is equivalent to the function:

$g(x)=-4\lvert x+1\rvert$

Together with a translation 5 units in the negative direction of the "x" axis. Since the range of g(x) is all the values of "y" that are smaller or equal to zero, if we translate 5 units in the negative direction of the y-axis the range is:

$R(f(x))=\mleft\lbrace y\parallel y\mright?\le5\rbrace$

or in interval notation:

$R(f(x))=(-\infty,-5\rbrack$
