Answer: P(red): 1/2

P(red or black):3/4

Step-by-step explanation: Count the total number of marbles. There are 8. Since there are 4 red marbles out of the 8, put this into a fraction. It will be 4/8, but simplify to 1/2. The P(red) is 1/2.

Since there are 4 red marbles and 2 black marbles, add them. There are 6 out of the 8 marbles. The fraction is 6/8 simplify to 3/4. The P(red or black) is 3/4.

Answer:

y =  2(x-1) (x-2)

x = 1 , x = 2

Step-by-step explanation:

Factorization :

2x^2 - 6x + 4 = 2x^2 -4x -2x + 4

                  =2x(x-2)-2(x-2)\\=(2x-2)(x-2)\\=2(x-1)(x-2)

Zeroes of y :

x - 1 =0 => x = 1\\x -2 = 0 => x = 2

If the fraction 414/x-10 is equivalent to -23 ​, find the value of x. Show your work. Use reasoning to find x.
NemiM [27]

Answer:

x = -8

Step-by-step explanation:

Solve for x by getting rid of the fraction.

414/(x-10) = -23

414 = -23(x-10)

414 = -23x + 230

184 = -23x

-8 = x
