Solve the system of equations and choose the correct ordered pair.
2х - бу = 8
5x - 4 y= 31
оа. (7, -1)
ов. (7,1)
ос. (1,-1)
od. (8, 2)

B)   x  = 7, y = 1 is the Solution of the given system.

Step-by-step explanation:

Here, the given system of equation is:

2х - бу = 8          (1)

5x - 4 y= 31    (2)

Now, to solve the given system, we need to eliminate a variable.

To remove variable x from the system, multiply (1) with 5, and (2) with -2 , we get:

10 x -30 y = 40

-10 x + 8y = -62

Add both equations, we get

10 x -30 y  -10 x + 8y   = 40 - 62

or, -22 y =  -22

or, y = 22/22  = 1  ⇒ y = 1

Putting y = 1 in (1) , we get

2x = 8 + 6 y = 8 + 6(1)  = 14

or, x  = 14/2 = 7

⇒ x = 7

Hence, x  = 7, y = 1 is the Solution of the given system.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
