Answer:
9a + 6b and 5c - 3d
Step-by-step explanation:
(a)
4a + 7b + 5a - b ← collect like terms
= (4a + 5a) + (7b - b)
= 9a + 6b
(b)
6c + 4d - c - 7d ← collect like terms
= (6c - c) + (4d - 7d)
= 5c - 3d
Answer:
Step-by-step explanation:
If a point (x, y) lies on a straight line, coordinates of the point will satisfy the equation.
Slope of a line passing through two points C(4, 5) and D(8, 10),
m = 
m = 
m = 
Equation of the line passing through C(4, 5) and slope m = 
y - y' = m(x - x')
y - 5 = 
y = 
y = 
If point B(4, 0) lies on the line CD,
0 = 
0 = 5
Which is not true.
Therefore, point B doesn't lie on line CD.
