4x - (9 - 3x) = 8x - 1
4x - (9) - -(3x) = 8x - 1
4x - 9 + 3x = 8x - 1
7x - 9 = 8x - 1 (-8x from each side)
-x - 9 = -1 (+9 to each)
-x = 8 (divide -1 from each side)
x = -8
Answer:
- Reagan needs to purchase 1346 centimeters. I think it solve like this (238+435)×2 =1346 cm.
- what length of fringe does Raegan need for the longer bedspread? The answer is :
1346 + 27×2 = 1400 cm.
What if there are mistakes, hope you sympathy and forgiveness !!!
Answer:
The graph should have a y-intercept of -8
Step-by-step explanation:
It seems like your question is incomplete, i can't see any options of graphs.
In order to find the second endpoint or a line segment given the first and the midpoint, you need to realize that the midpoint is an average of the two endpoints. Given that fact, we can derive this formula looking at x values of points A and B with midpoint M. Remember this is only looking at the x values.
(A + B)/2 = M
So if we are looking for A, we can solve for A and use this modified formula.
(A + B)/2 = M
A + B = 2M
A = 2M - B
Now we can do this with the y values of these points as well. We then have the coordinates of both parts of A.
