Two submersibles, one red and one blue, started rising toward the surface at the same time. They each rose at a constant speed.
The red submersible started rising from an altitude of 808080 meters below the surface. After 303030 seconds, it was 606060 meters below the surface.
The following equation gives the altitude (in meters relative to the surface) of the blue submersible as a function of time (in seconds).
A =-90+0.6tA=−90+0.6tA, equals, minus, 90, plus, 0, point, 6, t
Which submersible started rising from a higher altitude?

Otto used 6 cups of whole wheat flour and cause x cups of white flour in the recipe. what is the equation that can be used to find the value of y, the total amount of flour that otto used in his recipe and what are the constraints on the value of x and y? a y=6x; x is any interger greater than the equal to 0 and y is an interger greater than the equal to 6? b y=6x; is any real number greater than or equal to 0 and y is any real number greater than or equal to 6? c y=+6; x is any intger greater than or equal to 0 and y is an intger greater than or equal to 6? d y=x+6; x is any real number greater than 0 eqaul to 0 and y is any real number greater than or eqaul to 6?
