x = 2
Collect terms in x to one side of the equation and numeric values on the other side.
1 + 4x = - 5 + 7x ( subtract 7x from both sides )
1 + 4x - 7x = - 5
1 - 3x = - 5 ( subtract 1 from both sides )
- 3x = - 6 ( divide both sides by - 3 )
x = = 2
Answer:
Step-by-step explanation:
First, you need to find the slope of the line. To do this you need to choose two points on the graph. The points you are given are (-2, 1) and (4, 6). Then use these to find the slope.
You can then plug this and one of your chosen points into the slope-intercept formula
Answer:
(30-5n)
Step-by-step explanation:
The given sequence is :
25,20,15,10,5
Here,
First term, a = 25
Common difference = 20-25 = -5
We need to find the nth term of the given sequence. The formula for the nth term is given by :
So, the nth term of the above sequence is (30-5n).
