The general equation of a line is expressed as:
y = mx + b
where m is the slope and b is the y-intercept.
We are given the slope of the line and its y-intercept (m = 4/5, b = 1).
y = (4/5)x + 1
5(y - (4/5)x = 1)
5y - 4x = 5
The answer should be option D.
Answer: when the equations are equal, that is when x = 1 or x = 2
Step-by-step explanation:
The dog will receive the ball , when both equations intercept , that is , when both equations are equal. This implies :
- x + 2 = 2x
- x - 2x + 2 = 0
x(x-1) - 2 (x - 1 ) = 0
(x - 1 ) ( x - 2 ) =0
Therefore , x = 1 or x = 2
Answer: p= 5 miles
Step-by-step explanation:
20/4 = 5
Answer:
(9, 3 )
Step-by-step explanation:
under a reflection in the y- axis
a point (x, y ) → (- x, y ) , then
(- 9, 3 ) → (9, 3 )
