Answer:

x < -16, none of the solution sets are correct for the given equation.

Step-by-step explanation:

-1/4x > 4, multiply both sides by -4, don't forget when you multiply or divide by a negative you have to flip the sign.

x < -16

Find factors of x³+12x²-19x= -20

AleksAgata [21]

Answer:

No Factors

Step-by-step explanation:

$x^3-12x^2-19x+20 = 0\\Let \ p(x) = x^3-12x^2-19x+20$

Factors of 20 = ±1, ±2 , ±4 , ±5 , ±10 and ±20

±1, ±2 and ±3 are not the factors of given polynomial.

Putting x = 4 in the given polynomial

$p(4) = (4)^3+12(4)^2-19(4)+20\\p(4) = 64+192-76+20\\p(4) = 200$

So, x = 4 is not a factor of p(x)

Putting x = -4 in the given equation

$p(-4) = (-4)^3+12(-4)^2-19(4)+20\\p(-4) = -64+192-76+20\\p(-4) = 73$

So, x = -4 in the given equation

Putting x = 5 in the given equation

$p(5) = (5)^3+12(5)^2-19(5)+20\\p(5) = 125+300-95+20\\p(5) = 350$

So, x = 5 is not a factor of p(x)

Putting x = -5 in the given equation

$p(-5) = (-5)^3+12(-5)^2-19(-5)+20\\p(-5) = -125+300+95+20\\p(-5) = 290$

So, x = -5 is not a factor of p(x)

Putting x = 10 in the given equation

$p(10) = (10)^3+12(10)^2-19(10)+20\\p(10) = 1000+1200-190+20\\p(10) = 2030$

So, x = 10 is not a factor of p(x)

Putting x = -10 in the given equation

$p(-10) = (-10)^3+12(-10)^2-19(-10)+20\\p(-10) = -1000+1200+190+20\\p(-10) = 410$

So, x = -10 is not a factor of p(x)

Putting x = 20 in the given equation

$p(20) = (20)^3+12(20)^2-19(20)+20\\p(20) = 8000+4800-380+20\\p(20) = 12440$

So, x = 20 is not a factor of p(x)

Putting x = -20 in the given equation

$p(-20) = (-20)^3+12(-20)^2-19(-20)+20\\p(-20) = -8000+4800+380+20\\p(-20) = -2800$

So, x = -20 is not a factor of p(x)

From the above solution, we conclude that the given equation can not be factorized and thus, has no factors.

PLZ ANSWER ASAP! I WILL REWARD BRAINLIEST AND 12 POINTS FOR THESE THREE QUESTIONS!

bezimeni [28]

Answer:

1. 60%

2. $500

Explained:

10% = 50 in this case since 50 multiplied by 9 is 450

50 multiplied by 10 is 500

Which concludes that $500 was the original price and it was discounted by $50!

3. 16.4%

Explained:

I'll be saying the price is $100 for an example

If 12% is taken off the price, you still have to pay 88%

So, 88% in decimal form is 0.88. 100 multiplied by 0.88 equals 88.

Now we have to take off the 5%

So, after 5% you'll still have to pay 95%, and 88 multiplied by 0.95 equals 83.6

Now, if you subtract the 100 minus 83.6, it equals 16.4

Which means your answer is 16.4%

Hope I helped!
