There are 20 beads in a box, some black and some white; 6 more black than white. How many black, How many white? (first you make 2 equations using X and Y and then solve it)

Black beads=13

               White beads=7

Step-by-step explanation:

Black beads: y(x+6)

White beads: x

x+6=y

x+(x+6)=20

2x+6=20

2x=20-6

2x=14

x=7

white beads=7

black beads=x+6=7+6=13

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.

well what did you do it matters what you did : )
