It sounds like you want to solve for x. If so, then follow these steps:

2x-1 = r

2x-1 = 4x ... replace r with 4x

2x-1-2x = 4x-2x ... subtract 2x from both sides

-1 = 2x

2x =  -1

2x/2 = -1/2 .... divide both sides by 2

x = -1/2 is the fractional solution for x

x = -0.5 is the decimal solution for x.

--------------

If you want to figure out the value of r, then plug the x solution into the equation below and simplify

r = 4x

r = 4(-1/2)

r = -2

A spinner with 20 equal-sized sections has 5 red, 10 blue, 3 green, and 2 yellow sections. Ann pays $10 to spin the spinner. If
zhenek [66]

Answer:

The expected payoff for Ann is that she loses the game

Step-by-step explanation:

The expected payoff for Ann is that she loses the game, this is because only 5 out of the 20 sections allow Ann to win money, this is only 25% of the spinner. Meaning that 75% of the spinner will cause Ann to lose the game. Rolling two times increases the odds that she will lose the game. Since the greatest probability is that Ann will land on a section that causes her to lose the game, then this is the expected payoff.

Compute the missing data in the table for the following exponential function
kramer

Answer:

d. 1

Step-by-step explanation:

The base for this "exponential" function is sufficiently close to 1 that the function looks linear. The value corresponding to x=0 seems to be 1.00. Rounded to tenths, it is 1.0.

Explain why any rotation can be described by an angle between 0 degrees and 360 degrees
Oksanka [162]
Because if you rotate an object 360 degrees it’s like the object never moved because the object would still be in the same spot as if you didn’t move it
