Answer:
3 , 1 , -1 , -3
Step-by-step explanation:
5 - 2n
n = 1 ; 5 - 2n = 5 - 2*1 = 5 - 2 = 3
n = 2; 5 - 2n = 5 - 2*2 = 5 - 4 = 1
n = 3; 5 - 2n = 5 - 2*3 = 5 - 6 = -1
n = 4; 5 -2n = 5 - 2*4 = 5 - 8 = -3
First 4 terms are : 3 , 1 , -1 , -3
In order to subtract fractions, we must find a common denominator, then subtract the numerators.
The common denominator (LCM(3, 5)) is 15.
We must multiply the first numerator by 5, because 3*5=15 and the second numerator by 3 because 5*3=15.
We get 
.
All we need to do now is subtract the numerators: 
.
The answer is 14/15.
Answer:
See below
Step-by-step explanation:
r/6 <-6 multiply both sides by 6 to get
<u>r < - 36 </u>
<u />
<u> or</u> 4r+2 > 18 subtract 2 from both sides of the equation
4r > 16 divide both sides by 4
<u> r > 4 </u>
Answer:
1) 25x + 15y = 750
2) 25. On a graph it would look like : (25,0)
3) 15. On a graph it would look like : (15,0)
4) 25x - 750 = 15y or 15y - 750 = 25x
