Albert thought of a number, added 5, multiplied the result by 2, took away 6 and then divided by 2 to give an answer of 8

To find Albert's original number we have to work backwards. So everything albert did we have to do the reverse.

Starting with 8:

8*2 = 16 + 6 = 22/2 = 11- 5 = 6

Now, lets check it and start from the beginning with this new number (6), and follow everything Albert did and we will get 8. 

6+5= 11*2= 22-6 = 16/2 = 8

The answer is 6 ....you just have to do the steps backwards and it will result faster.
6+5=11
11*2=22
22-6=16
16/2=8

What is the completely factored form of the expression 16x2 + 8x + 32?
allochka39001 [22]
<span>8 is a common factor for all coeficients so we factor it out first: 8(2x^2 + x + 4). Now we have to check can we factor the quadratic equasion in the brackets to linear factors. To do that we need to check is the discriminant D=b^2 - 4ac > 0 where a=2, b=1 and c=4. When we insert our numbers, we get: D= -31. We see that D < 0 so 8(2x^2 + x + 4) is the completely factored form.</span>

The circle below is centered at the point (-3/4) and has a radius of length 3 what is its equation??
Agata [3.3K]
{x-(-3/4)}^2=3^2
(x+3/4)^2=9
{(4x+3)/4}^2=9
(4x+3)^2/16=9
(4x+3)^2=9*16
16x^2+2*4x*3+3^2=144
16x^2+24x+9=144
16x^2+24x+9-144=0
16x^2+24x-135=0

Which of the following functions shown in the table below is not an exponential function?
kramer

Answer:

B. f(x)

D. h(x)

Step-by-step explanation:

An exponential function will have a common ratio.

We check and see if the consecutive terms has a common ratio.

For f(x),

\frac{5}{2}  \ne \frac{10}{5}

This is not an exponential sequence.

For g(x), we have:

\frac{2}{1}  =  \frac{4}{2}  =  \frac{8}{4}  = 2

For h(x),

\frac{1.25}{1}  \ne \frac{1.5}{1.25}

This is not an exponential sequence

For k(x),

\frac{16}{64}  =  \frac{4}{16}  =  \frac{1}{4}  =  \frac{0.25}{1}

The marching band walks 1/15 miles in 1.5 minutes. At this rate, how many minutes will it take to complete 1 mile? Record your a
ipn [44]

Answer:

It will take 22.5 minutes to complete 1 mile

Step-by-step explanation:

From the question,

The marching band walks 1/15 miles in 1.5 minutes

First we will determine the miles cover in 1 minute

If the marching band walks 1/15 miles in 1.5 minutes

then, they will cover x miles in 1 minute

x = \frac{1/15 * 1}{1.5}\\

Then,

x = \frac{1/15 }{1.5}

x = 2/45 miles

∴ 2/45 miles are covered in 1 minute

Now,

If 2/45 miles are covered in 1 minute

Then, 1 mile will be covered in y minute

y = \frac{1 * 1}{2/45}

y =\frac{1}{2/45} \\y = \frac{45}{2}\\

∴ y = 22.5 minutes

Hence, it will take 22.5 minutes to complete 1 mile
