Answer:
Sum of those numbers are 50
Step-by-step explanation:
Let x represent a number that is twice as far away from 13 than 22.
The number can't be less than 13 but will be between 13 and 22 or slightly more than 22 otherwise it will be far away from both.
Thus;
|x - 13| = 2|x - 22|
It's in absolute form, so we will square both sides to get rid of the absolute brackets.
Thus;
(x - 13)² = 4(x - 22)²
x² - 26x + 169 = 4(x² - 44x + 484)
x² - 26x + 169 = 4x² - 176x + 1936
4x² - x² - 176x + 26x + 1936 - 169 = 0
3x² - 150 + 1767 = 0
Using quadratic formula, we have;
x = 19 or x = 31
Thus,the sum of the 2 numbers = 31 + 19 = 50
Answer:
x = -.25
Step-by-step explanation:
x - 3.75 = -4
x = -.25
Where f(x)=0 is the zeros of the funciton
factor out the common factor of all of them which is 9x
f(x)=9x(x^2+2x-15)
what 2 numbers multiply to get -15 and add to get 2?
5 adn -3
f(x)=(9x)(x+5)(x-3)
set to zero
9x=0
x=0
x+5=0
x=-5
x-3=0
x=3
zeroes at x=-5, 0,3
If you would like to know the number of minutes of long-distance calls you made, you can calculate this using the following steps:
3.3 cents = $0.033
m = $3.40 / 3.3 cents
m = $3.40 / $0.033 = 3.40 / 0.033
m = 103.03 minutes
The correct result would be <span>103.03 minutes.</span>
Answer: 61 is the 12th term
Step-by-step explanation: All we have to do is plug N=12 in the formula to find the 12th term.
a(12)=-5+6(12-1)
