Answer:
x<±1 and x< -3
Step-by-step explanation:
Given the inequality x^2-1/3x+9<0, we are to find the values of x that satisfies the inequality
x^2-1/3x+9<0
x^2-1/3x+9 (3x+9)²<0* (3x+9)²
(x^2-1)(3x+9) < 0
x²-1 < 0 and 3x + 9 <0
x²-1 < 0
x²<1
x<±√1
x<±1
Also 3x + 9 <0
3x < -9
x < -9/3
x < -3
Hence the required values of x are x<±1 and x< -3
Answer:
225 + 63n for n- a natural number,
set 512=225+63n to find total number of weeks
63=21*3
use n=4 to solve the amount saved in 4 weeks
they wont 60*4=240, 240+12, 252+225=477
how much are the saving a day
what do they need to put up to have enough in 4 weeks
how much a day do the need to save to go in 1 week
etc
Step-by-step explanation:

Different ways to make the number 15,638 with
hundreds, tens and ones are: <span>
156 hundreds, 3 tens and 8 ones
150 hundreds, 63 tens and 8 ones
141 hundreds, 161 tens and 28 ones
<span>we can write the numbers in thousands, hundreds, tens and ones
by using the place values. We use these ten numbers 0,1,2,3,4,5,6,7,8,9 along
with the concept of place value.</span></span>
The probability of all possible outcomes is always 1, meaning 100%.
In this case the probability of rolling a 1,2,3,4,5, or 6 is:
1/6+1/6+1/6+1/6+1/6+1/6
6(1/6)
6/6
1
