Without solving explain why the equations do not have solutions​
Talja [164]
<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>

5÷6 is 5/6. what is 1/6 of 5
mel-nik [20]
\dfrac{1}{6} \text{ of } 5

"of" is written as "x" in number statement:
= \dfrac{1}{6} \times 5

Write 5 as fraction:
= \dfrac{1}{6} \times  \dfrac{5}{1}

Multiply:
= \dfrac{5}{6}

Just 4 people who need helppp
Arturiano [62]

Answer:

1/2 ÷ 4 = 8

Step-by-step explanation:

Dividing fractions is as easy as pie. Flip the second and multiply.

1/2 ÷ 4 = 1/8

A whole number secretly has a 1 underneath, like this: 4/1

Flip the second number over to get 1/4, then multiply straight across.

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

Try to do the same for the other answers and see if they're right (they're not).

1/8 x 1/6 = 1/48

1/3 x 1/4 = 1/12

1/9 x 1/2 = 1/18

We want to solve
3e^{2x}+5=27

Subtract 5 from each side.
3e^{2x}=22
Divide each side by 3.
e^{2x}=7.3333
Take natural logs of each side.
2x=ln(7.3333)=1.9924
Divide each side by 2.
x = 0.9962

Answer:  x = 0.996  (nearest thousanth)

the vertex of this parabola is at (3,5). When the y-value is 6, the x-value is -1. What is the coefficient of the squared term i
otez555 [7]
Now, assuming is a vertical parabola, so the squared variable is the "x", let's do some checking.

\bf \qquad \textit{parabola vertex form}\\\\&#10;\begin{array}{llll}&#10;\boxed{y=a(x-{{ h}})^2+{{ k}}}\\\\&#10;x=a(y-{{ k}})^2+{{ h}}&#10;\end{array} \qquad\qquad  vertex\ ({{ h}},{{ k}})\\\\&#10;-------------------------------\\\\&#10;vertex&#10;\begin{cases}&#10;h=3\\&#10;k=5&#10;\end{cases}\implies y=a(x-3)^2+5&#10;\\\\\\&#10;\textit{we also know that }&#10;\begin{cases}&#10;y=6\\&#10;x=-1&#10;\end{cases}\implies 6=a(-1-3)^2+5&#10;\\\\\\&#10;1=a(-4)^2\implies 1=16a\implies \cfrac{1}{16}=a
