Let...

x=ones digit

x-3=tens digit

The number in terms of x would be...

10(x-3)+x = 11x-30

The number with its digits reversed would be...

10(x)+x-3 = 11x-3

And...

11x-30+11x-3=143     We can solve for x!

22x=176

x=8

The number would be 58.

answer: 58

The polynomial p(x)=x^3-19x-30 has a known factor of (x+2)
riadik2000 [5.3K]

Answer:

(x+2) (x+3) (x-5)

Step-by-step explanation:

x³-19x-30 = (x+2) (x²+ax-15)  ... x³=x*(1*x²)   while -30= (2)*(-15)

x³ +<u> 0</u>*x² - 19x -30 = x³ + (<u>2+a</u>)x² + (2a-15)x -30

2+a = 0

a = -2

x³-19x-30 = (x+2) (x²-2x-15) = (x+2) (x+3) (x-5)

Answer:

The constant of proportionality is 6

Step-by-step explanation:

Recall the equation for direct variation is y=kx where y varies directly with x and k is the constant of proportionality. If we take any listed coordinate point, we can determine the value of k. I will use (20,120) as an example:

y=kx\\\\120=k(20)\\\\6=k

Therefore, the constant of proportionality is 6

The poorest person in a country has 50$ and the richest had $9.956. How much less money does the poorest have
Alecsey [184]
What you need to do is subtract since the key word "How much Less money"  is in it.

$9.956-$50 = 40.044$
