Without solving explain why the equations do not have solutions​

Mathematics
1 answer:
Talja [164]3 years ago
5 0
<h2>Examining the equation</h2>

We have 2 terms:

\sqrt{x+2} and \sqrt{4x+1}

For the sum of these to equal a negative number, in this case -3, one of these terms would have to be negative.

<h2>So what's the problem?</h2>

The function \sqrt{x} (square root of x) only returns positive values!

(See the attached image for a graph of \sqrt{x})

Since neither of the terms can be negative, it can't be equal to -3. In other words, no matter what we put as x, we can't solve the solution, so we say that the equation <em>does not have any solutions.</em>

We are given the following numbers: 13, 14, 22, 52, 63, 74. Calculate a by adding the numbers and then rounding the sum to the n
galina1969 [7]

Answer:

a-b=10

Step-by-step explanation:

add all the numbers then round

13+ 14+ 22+ 52+ 63+ 77=241

Round to the nearest ten

a =240

first rounding each number to the nearest ten and then add

13+ 14+ 22+ 52+ 63+ 77

10+10+20+50+60+80 =230

b= 230

a-b = 240-230

      = 10
