Substitute -2 into negative 2Y minus 8X equals six

Answers

When the value of x = -2 then, the value of y is 5.

When the value of y = -2 then the value of x is -0.25

Explanation:

Given:

-2y - 8x = 6

Considering x = -2

Then, we have to substitute the value of x = -2 in the equation.

-2y - 8(-2) = 6

-2y + 16 = 6

10 = 2y

y = 5

So, when the value of x = -2 then, the value of y is 5.

Considering y = -2

Then, we have to substitute the value of y = -2 in the equation.

-2 (-2) - 8x = 6

4 - 8x = 6

-2 = 8x

x = -0.25

So, when the value of y = -2 then the value of x is -0.25

7) Drawing 2 cards that are all 8 from a deck of cards? __________

Answers

ok so a deck has 52 cards

there are 4 suits so there are 4 cards with 8 on them (8 of clubs, hearts, spades, diamonds)

so
probability is
(desired ourcome)/(total possible)
you have 4 chances ouut of 52 for picking a 8 on the first try
on the second try, you have a 3 out of 51 (assuming you picked an 8 first and you didn't replace it)

multiply them since they are dependent on each ohter
4/52 times 3/51=12/2652=1/221

probability is 1/221

thats statistics and probablilities :D hope that helped

The slope of a line is 0 and the y-intercept is 6 what is the equation of the line written in slope-intercept form

Answers

Answer:

The slope-intercept form of the the line is y=6.

Step-by-step explanation:

The slope intercept form of a line is

$y=mx+b$

where, m is slope and b is y-intercept.

It is given that the slope of a line is 0 and the y-intercept is 6.

Substitute m=0 and b=6 in the above equation.

$y=(0)x+6$

$y=0+6$

$y=6$

Therefore the slope-intercept form of the the line is y=6.

y = 6. Since there is no slope, if you plug 0 into y = mx + b where m = slope, then you get y = (0)x +b, which leads to y = b. Since b = y-intercept, b = 6. Therefore your equation is y = 6
