Please help!! the answer isn’t (0,2) even though i thought it was and other people on here thought it was. Solve the system by the elimination method. Check your work.

2a + 3b = 6
5a + 2b - 4 = 0

That's really wierd I would think you are right.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
