−x−(−1.2x−6.9)=10+2(0.3x-10)

Slope intercept form? A line passes through the point (10,4) and has a slope of -1 over 2 .

Law Incorporation [45]

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

We have the slope $m=-\dfrac{1}{2}$ and the point (10, 4).

Substitute the value of slope and the coordinates to the equation of line:

$y=-\dfrac{1}{2}x+b\\\\4=-\dfrac{1}{2}(10)+b\\\\4=-5+b\qquad|\text{add 5 to both sides}\\\\9=b\to b=9$

Answer: $y=-\dfrac{1}{2}x+9$

The second option is the correct answer

$16x^{4}+40x^{3} -24x^{2}$

The expression given to us is:

$8x^{2} (5x+2x^{2}-3 )$

Herein, we can simplify it by opening up the bracket and multiplying each term inside the bracket by the term which is outside the bracket.

Thus, we get:

$8x^{2} (5x+2x^{2}-3 )=8*5x^{2+1} +8*2x^{2+2}-8*3x^{2}$

$40x^{3} +16x^{4}-24x^{2}$

Rearranging the above expression in descending order of power we get:

$16x^{4}+40x^{3} -24x^{2}$

From the given options we can see this is the second option. Hence the second option is the correct answer.

Answer:

44,278,106,022,432,739,384.375 = 1/8 of ((1+√5)/2)^100/√5

Step-by-step explanation:

We separate the x10^21 number into 2 so that becomes x10^8 number with decimal of .75 when it is a x10^21 split into 2 large parts and a small subtraction creates the third step. we have found 1/4 then we half.

354224848179261915075 / 4

= 000000000000065478768.75

354224 848179000000000/4

-88556212044.8

= 354 has become a 12 digit number temporary starting with 885 the decimal .8 is simply put in front

3542248481 79- so it has become a x10^20 number. 885562120448,65478768.75

We arrange the comma's

88,556,212,044,865,478,768.75

88,556,212,044,865,478,768.75 is division by 4

=354224848179261915075

88,556,212,044,865,478,768.75 /2

= 44278106022 (/2) 432739384.375(/2) in two part.

= 44278106022,432739384.375 replace /2 with comma

= 44,278,106,022,432,739,384.375 replace all other comma.
