First isolate y
3x + 2y = 14
-3x -3x
2y = -3x + 14
y = -3/2x + 14/2
y = -3/2x + 7
X-intercept is found when y = 0
0 = -3/2x + 7
-7 = -3/2x
x = 14/3
x-in. = (14/3,0)
Let's represent the numbers by : x, x+1, x+2, x+3
x+x+1+x+2+x+3=40 The third number in the sequence is x+2
4x+6=40 8.5+2=10.5
4x+6-6=40-6 Therefore the third number in the sequence is
4x=34 10.5
4x/4=34/4
x=8.5
Answer: -3n+31
Step-by-step explanation:
1. 28-55=3
25-22=3
22-19=3
19-16=3
This means that n = -3 as we are subtracting
2. We then do the opposite, we take the first number and we add 3 instead of taking it away we get 31.
That is how you get your answer
-3n+31
