The weight in pounds, x, and the jump height in feet, y, of a bicycle can be modeled by the trend line. What does the y-intercept for the trend line represent? A) the y- intercept represents the minimum bicycle weight. , B) The y-intercept represents the maximum bicycle weight. C) The y-intercept represents the jump height at the greatest bicycle weight., D) The y-intercept represents the jump height at the minimum bicycle weight. (Will Mark Brainliest. Only correct answer please).

D) The y-intercept represents the jump height at the minimum bicycle weight.

Step-by-step explanation:

Since the bicycle weight starts at 0, which everyone knows means "minimum", and the jump height marks at 11.5 when you look at the y-axis, it clearly means that that is the jump height at the lowest possible bicycle weight.

b). 4320 have a nice day

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
