Answer:

(x^2-4)^2 = 9

Step-by-step explanation:

First, isolate the constant:

x^2-8x = -7

Then, since (a-b)^2 = a^2-2ab+b^2, you should add 16(4^2) to both sides:

x^2-8x+16 = 9

Now, we can rewrite the right-hand side as (a-b)^2:

(x-4)^2 = 9

Answer:

(x - 4)^2 = 9

Step-by-step explanation:

<u>Completing the square</u>

x^2 - 8x + 7 = 0
x^2 - 2*4x + 16 - 9 = 0

(x^2 - 2*4x + 4^2) = 9

(x - 4)^2 = 9

<u>The blanks are</u>

- 4 and 9

M= i + r ; solve for r

Alex777 [14]

Answer:

m - i = r

Step-by-step explanation:

In this question, you are solving for "r".

Solve:

M= i + r

We have to get "r" by itself, so subtract "i" from both sides.

m - i = r

Since we found what "r" is, we can't solve any further.

m - i = r would be your answer.

Which of the following statements best describes the graph of -5x+2y=1

ahrayia [7]

The answer is the third option.
x and y are both to the first degree so we know it makes a straight line.
Next check the ordered pairs to see which set are true in the equation.

Let v1 =(-6,4) and v2=(-3,6) compute the following what i sthe angle between v1 and v2

Agata [3.3K]

$\bf ~~~~~~~~~~~~\textit{angle between two vectors }
\\\\
cos(\theta)=\cfrac{\stackrel{\textit{dot product}}{u \cdot v}}{\stackrel{\textit{magnitude product}}{||u||~||v||}} \implies 
\measuredangle \theta = cos^{-1}\left(\cfrac{u \cdot v}{||u||~||v||}\right)\\\\
-------------------------------$

$\bf \begin{cases}
v1=\ \textless \ -6,4\ \textgreater \ \\
v2=\ \textless \ -3,6\ \textgreater \ \\
------------\\
v1\cdot v2=(-6\cdot -3)+(4\cdot 6)\\
\qquad \qquad 42\\
||v1||=\sqrt{(-6)^2+4^2}\\
\qquad \sqrt{52}\\
||v2||=\sqrt{(-3)^2+6^2}\\
\qquad \sqrt{45}
\end{cases}\implies \measuredangle \theta =cos^{-1}\left( \cfrac{42}{\sqrt{52}\cdot \sqrt{45}} \right)
\\\\\\
\measuredangle \theta =cos^{-1}\left( \cfrac{42}{\sqrt{2340}} \right)\implies \measuredangle \theta \approx 29.74488129694^o$
