Find the limit of the function by using direct substitution as X approaches one lim(x^2-8x -2)

Leno4ka [110]

Answer:

$lim_{x \to 1} x^2 -8x -2 =-9$

Step-by-step explanation:

For this case we want to find the following limit:

$lim_{x \to 1} x^2 -8x -2$

And we can find the limit distirbuting into each term like this:

$\lim_{x \to 1} x^2 -8 lim_{x \to 1} x -lim_{x \to 1} 2$

And replacing we got:

$1^2 - 8*1 -2 = 1-8-2 = -9$

So then the final answer for this case is:

$lim_{x \to 1} x^2 -8x -2 =-9$

What is the area? write your answer as a fraction or as a whole or mixed number

Soloha48 [4]

$\underline \mathcal \pink{ GIVEN}$

Base = 2 9/10 km
Height = 4 6/7 km

$\underline \mathcal \purple{ TO \: FIND}$

Area of the triangle

$\underline \mathcal \blue{CALCULATION}$

$\qquad \tt \leadsto \: area = \frac{1}{2} \times base \times height$

$\qquad \bf \nrightarrow \: area = \frac{1}{ \cancel2} \times \cancel2 \frac{9}{10} \times 4 \frac{6}{7}$

$\qquad \bf \nrightarrow \: area = \frac{9}{ \cancel{10}} \times \cancel4 \frac{6}{7}$

$\qquad \bf \nrightarrow \: area = \frac{9}{ 5} \times 2 \frac{6}{7}$

$\qquad \bf \nrightarrow \: area = \frac{108}{ 35} \approx3.08 \: {km}^{2}$

Thus, The area of the triangle is 3.08 kilometers...~

How do i solve for y: 2x-3y=8 Please help me

Mademuasel [1]

You have to leave Y by itself in one side. To do that, you need to subtract 2x from both sides. You're now left with -3y = 8-2x. Last step is that you divide 3y, 8, and -2 by -3.

Good luck :)
