2 Points What can you say about the end behavior of the function f(x)=-4x + 6x2 - 52?

Just look at coefficient of highest power of x (leading coefficient): 6. It is x^2, so limf(x) x—>infinity and limf(x) x—>-infinity are both infinity

Answer:

Step-by-step explanation:

Show that if 3x – 7 = 5, then x = 4.

Here, our given statement is 3x – 7 = 5, and we're asked to prove x = 4.

x=4

Statements Reasons

1. 3x – 7 = 5 Given

2. 3x – 7 + 7 = 5 + 7 Addition of 7 to equation (1)

3. 3x + 0 = 5 + 7 Substitution of –7 + 7 = 0 into (2)

4. 3x = 5 + 7 Substitution of 3x + 0 = 3x into (3)

5. 3x = 12 Substitution of 5 + 7 = 12 into (4)

6. 3x⁄3 = 12⁄3 Dividing equation (5) by 3

7. x = 12⁄3 Substitution of 3x⁄3 = x into (6)

8. x = 4 Substitution of 12⁄3 = 4 into (7)

Is there such a thing as being too descriptive? Yep, and that was it, since over half the proof was devoted to telling the reader how to do arithmetic. We'll typically take numerical computation for granted, and write proofs like this:

−px+r=−8x − 2, x=?<br> now i have to do this problem, and i dont know how, help?

Taya2010 [7]

-px + r = - 8x - 2

-px + r + 8x +2 = 0

-px +8x = -r -2

x(8-p) = -r -2

x= $\frac{8-p}{-r-2}$ =

$\frac{8-p}{-r-2}$

By the Law of Sine,
$\frac{ \sin(77) }{89} = \frac{ \sin(46) }{x}$
Solve for x and get x = 65.7.

The area of the sector of a circle with a radius of 8 centimeters is 125.6 square centimeters. The estimated value of pi is 3.14

tangare [24]

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta\pi r^2}{360}\qquad 
\begin{cases}
\theta=\textit{angle in degrees}\\
r=radius\\
----------\\
r=8\\
A=125.6
\end{cases}
\\\\\\
360A=\theta\pi r^2\implies \cfrac{360A}{\pi r^2}=\theta\implies \cfrac{360\cdot 125.6}{\pi 8^2}=\theta$
