Answer:
12 m
Step-by-step explanation:
The path of a football has been modeled by the equation:
where h represents the height and d represents the horizontal distance.
When the ball lands, it means that its height is back at 0 metres. This means that we have to find horizontal distance, d, when height, h, is 0.
=> 
∴ d = 0 m
and
10d - 120 = 0
=> d = 120 / 10 = 12 m
There are two solutions for d when h = 0 m.
The first solution (d = 0 m) is a case where the ball has not been thrown at all. This means the ball has not moved away from the football player and it is still on the ground.
The second solution is the answer to our problem (d = 12 m). The ball lands at a horizontal distance of 12 m

Answer:
slope-intercept form y= -2/3 x + 490 slope is -2/3 y intercept is (0.490)
Step-by-step explanation:
2x+3y= 1470
3y= 1470-2x
y= 1470/3- 2/3 x
y= -2/3 x+ 490
slope is -2/3 and y intercept is 490 when x =0
the graph represent the amount of sandwiches that Sal's shop sold, where x is the number of sandwiches and y is the number of wraps sold. so that x won't exceed 735 sandwiches : 0≤x≤735 and 0≤ y≤490.
<u>total profit is 1593.</u>
2x+3y= 1593
y= -2/3 x + 531
similar : the two functions have the same slope -2/3
difference: 0≤ y≤531
0≤x≤796.5
the two line are parallel
