Answer:

Step-by-step explanation:
1. Combine like terms
2y-7y = -5y
-5y=5
2. Divide by -5 and the answer is 
Let g(x,y) be the midpoint of the segment ef;
So, x = (4+1)/2; then x = 5/2;
y = (-4+7)/2; then y = 3/2;
Finally, g(5/2,3/2).
Answer:
2
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1) where (x1, x2) and (y1, y2) are points on the line
Plug in the points A (-3, -2) and B (1, 6)
(y2 - y1) / (x2 - x1)
(6 + 2) / (1 + 3)
8 / 4
= 2
So, the slope of line segment AB is 2.
Answer:
x = -4
Step-by-step explanation:
1.
1.2 x^4 ( 4 x² + 3 x + 1 ) = 4.8 x^6 + 3.6 x^5 + 1.2 x^4
2.
( 4 x - 3 ) ( 2 x² - 7 x + 1 ) = 8 x³ - 28 x² + 4 x - 6 x² + 21 x - 3 =
= 8 x³ - 34 x² + 25 x - 3
3.
( x² + 4 x - 3 ) ( 2 x² + x + 6 ) =
= 2 x^4 + x³ + 6 x² + 8 x³ + 4 x² + 24 x - 6 x² - 3 x - 18 =
= 2 x^4 + 9 x³ + 4 x² + 21 x - 18
