Find a real number between ewch pair of numbers 16.45 and 13/2
1 number
explanationif 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.
simplifying
5(x + -6) = 2(x + 3)
reorder the terms:
5(-6 + x) = 2(x + 3)
(-6 * 5 + x * 5) = 2(x + 3)
(-30 + 5x) = 2(x + 3)
reorder the terms:
-30 + 5x = 2(3 + x)
-30 + 5x = (3 * 2 + x * 2)
-30 + 5x = (6 + 2x)
solving
-30 + 5x = 6 + 2x
solving for variable 'x'.
move all terms containing x to the left, all other terms to the right.
add '-2x' to each side of the equation.
-30 + 5x + -2x = 6 + 2x + -2x
combine like terms: 5x + -2x = 3x
-30 + 3x = 6 + 2x + -2x
combine like terms: 2x + -2x = 0
-30 + 3x = 6 + 0
-30 + 3x = 6
add '30' to each side of the equation.
-30 + 30 + 3x = 6 + 30
combine like terms: -30 + 30 = 0
0 + 3x = 6 + 30
3x = 6 + 30
combine like terms: 6 + 30 = 36
3x = 36
divide each side by '3'.
x = 12
simplifying
x = 12
this should .
