Answer: Distance between dolphin and helicopter = 93.5 feet
Explanation:
Distance at which dolphin swimming below the ocean= (-) 18 feet
(it is represented as the negative number as it denotes the distance below the ocean)
Distance at which helicopter is above the ocean = (+) 75.5 feet
(it is represented as the positive number as it denotes the distance above the ocean)
Distance between dolphin and helicopter = 75.5 - (-18) feet
= 75.5 + 18 feet
= 93.5 feet
On Venus the person is 153 lbs and on Mars it is 102 lbs.The difference is 51 lbs
Answer:
y= 2x - 5 equation has a slope of 2 and a y intercept of -5
Step-by-step explanation:
Given:
The slope = 2
Intercept of y = -5
To Find:
The equation of the line = ?
Solution:
The slope-intercept form of a line is a way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable. The slope is the steepness of the line, and the y-intercept is the place the line crosses the y-axis.
The equation of the line in the slope intercept form is
y = mx+b
where
m is the slope
b is the y intercept
Now substituting the given values we get
y = (2)x + (-5)
y= 2x - 5
