Answer:

x= 0, y = -1

Step-by-step explanation:

5x + 16y = -16

-9x – 8y = 8.     , multiply both sides of this equation by 2

 5x + 16y = -16

-18x – 16y = 16  , add both equations so the y will eliminate

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

-13x           = 0,  divide both sides by -13

    x = 0

5·0 + 16y = -16, substitute x= 0 in the first equation and solve for y

        16y = -16 , divide both sides by 16

          y = -1

The solution of the system of equation is the point ( x= 0, y = -1)

Find the probability of drawing an 8 and then a queen (with replacement) from a standard deck of cards
murzikaleks [220]

Prob (8) = 4/52 = 1/13

Prob(Queen) = 4/52 = 1/13

Prob ( 8 then a queen) = 1/13 * 1/13 = 1/169 answer

The probabilities are multiplied beause the 2 events are independent

What are the coefficients in the expression x-3y-7xy+4?
IRINA_888 [86]

The coefficients in the expression x-3y-7xy+4 is -3 and -7.

The coefficient of x are 1

-3y=3

-7xy=-7

What is coefficients?

A coefficient is a number or quantity that is associated with a variable. Typically, it is an integer multiplied by the variable and written next to it. The variables which do not have a number with them are assumed to be having 1 as their coefficient. For example, 3 is the coefficient of x in the expression 3x, but 1 is the coefficient of x2 in the expression x2 + 3. A coefficient, in other words, is a multiplicative factor in terms of a polynomial, a series, or any expression. Consider the following expression, which shows that 5 is the x2 coefficient and 8 is the y coefficient.
