Answer: x = 7/2 and 3

Step-by-step explanation: Rewrite and factor

2x² —13x + 21 = 0

2x - 7 = 0. x = 7/2

x - 3 = 0 x = 3

If a person rolls a six-sided die and then draws a playing card and checks its color, describe the sample space of possible outc

ASHA 777 [7]

Answer:

S = {1B, 2B, 3B, 4B, 5B, 6B, 1R, 2R, 3R, 4R, 5R, 6R}

Step-by-step explanation:

The sample space is the set of all possible outcomes in the experiment of rolling a six-sided die and then drawing a playing card and checking its color.

There are 6 possible outcomes for the die roll and two for the color of the card, which yields a total of 12 possible outcomes. The sample space is:

S = {1B, 2B, 3B, 4B, 5B, 6B, 1R, 2R, 3R, 4R, 5R, 6R}

Find an equivalent expression for each expression by simplifying. (3x - 5y) + 7y

sertanlavr [38]

This question is quite simple really. They are basically asking you to combine like terms. You have two different figures with the variable y, so you just combine the them. It would then be 3x + 2y. You cannot simplify this equation any further since there is nothing to solve for or anymore like terms to combine.
