I am to mental for this math... XD plz h e l p

a ≥

Step-by-step explanation:

You would solve this exactly as if the ≥ sign was an equal sign:

≥   [Given]

3a ≥ -64   [Multiply 4 on both sides of the sign]

a ≥   [Simplify]

Hope this helps! I apologize if I'm incorrect

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.
