We can write the equation in point-form in this case. The equation should be:
y-y1 = m(x-x1)
y and x can be any point in the line, so we leave them just like that in the equation, we don’t have to add any numbers to them. m is the slope of the line, and (x1, y1) is the given point in the line, which is (-1, 1) in this case.
Now, just substitute the number in,
y - 1 = -2 [x - (-1)]
y - 1 = -2 (x+1)
y - 1 = -2x - 2
2x + y + 1 = 0
So, 2x + y + 1 = 0 is your answer.
Y=200+50x and x is how many months
Answer: It is 2.
Step-by-step explanation:
Make both equation equal to each other and solve for x, as following:
- Add like terms.
- Factor the equation.
Substitute the value of x obtained into any of the original equations to obtain the y-coordinate.
Then, this is:
Answer:
The first three terms are: 25, 125 and 625
Step-by-step explanation:
Given

The first three terms
The nth term of a geometry progression is:
So, we have:
First term: 
Second term: 
Third term: 
Answer:12w=10212w=102.
We move all terms to the left:
12w-(10212w)=0
We add all the numbers together, and all the variables
-10200w=0
w=0/-10200
w=0
