Answer:

(-2, -4) or x = -2     y = -4

Step-by-step explanation:

Solve with subsitution

y-3x=2

y=-2x-8

1. Substitute -2x - 8 in for the y in y - 3x = 2                          (-2x - 8) - 3x = 2

2. Solve for x.  Combine like terms.                                               -5x - 8 = 2

3. Solve the one step equation.                                                          <u>  +8  +8</u>

                                                                                                              <u>-5x</u> = <u>10</u>

                                                                                                               -5     -5

                                                                                                                x = -2

4. Substitute the -2 in for x in either equation.                                y = -2x - 8

                                                                                                           y = -2(-2) - 8

                                                                                                           y = 4 - 8

                                                                                                           y = -4

Answer:

y-3x=2......1

y=-2x-8 ......2

substituting value of y in equation 1

-2x-8-3x=2

-5x=2+8

x=10/-5=-2

substituting value of x in equation 1

y-3×(-2)=2

y+6=2

y=2-6=-4

x=-2

y=-4

Rolling a die. What is the sample space of the experiment? What is the probability of getting a 1 or a 2?
Anvisha [2.4K]

A die has 6 sides, so rolling a 1 out of all six would be 1/6 which equals a 0.16% chance and same goes for a 2/6.

(Mark as brainliest if I helped in anyway, pls and thanks:))

King Henry the 8th had six wives,some of which had the same names.One more was named Catherine(although with different spellings
valentinak56 [21]
2 more were named Catherine because since he had 6 wives, 2 were named Anne with a different spelling and since Jane is only one wife that means 2 wives plus 1 wife equals 3 but then there was Catherine so 2 wives plus 2 wives equals 4 wives so you subtract 4 wives from 6 wives and you get 2 wives or 2 Catherines.
