Answer:
720
Step-by-step explanation:
120/10 to find his feet per second which is 12 feet per second
12*60
since there are 60 seconds in a minute
= 720
Answer:
y = -4/5x - 5
Step-by-step explanation:
4x + 5y = 45
we need to write it in slope intercept form, so:
5y = -4x + 45
y = -4/5x + 45/5
y = -4/5x + 9
The line is parallel so the slope will be -4/5x, point ( -5 -1 )
y = mx + b
-1 = -4/5(-5)+b
-1 = 4 + b
-1 - 4 = b
-5 = b
y = -4/5x - 5
The equation of the line that passes through the point (-5, -1) and is parallel to the line 4x + 5y = 45 is .
Given the parameter:
Equation of the original line: 4x + 5y = 45
Point of the parallel line: (-5,-1)
First, we determine the slope of the original line:
4x + 5y = 45
4x - 4x + 5y = -4x + 45
5y = -4x + 45
y = (-4/5 )x + 45/5
y = (-4/5 )x + 9
Hence, the slope is -4/5.
Since the slope of the parallel line will be the same as that of the original line.
Plug the slope m = -4/5 and point (-5,-1) into the point-slope formula and simplify.
( y - y₁ ) = m( x - x₁ )
Therefore, the equation of the parallel line is .
