Three more than twice the sum of a number and half the number equals 105. Which equation models this relationship? 2 (x + one-half x) + 3 = 105
2 x + one-half x + 3 = 105
2 x + 3 = one-half x + 105
2 (x + 3) = one-half x + 105

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.

i dont know

step-by-step explanation:

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.
