Answer:

The value of x is 5/4 and y is -5.

Step-by-step explanation:

  1. Firstly, you have to make the 1st equation as (1)<em> </em>and make 2nd equation as (2).
  2. Secondly, you have to elimimate one of the variable. I choose to eliminate x in order to get rid of x, I add (1) and (2) together as -4x+4x = 0.
  3. Thirdly, you can solve the value of y. Then after getting y value, you can substitute y value into any equation. I choose to put y value into (1).
  4. Lastly, you can solve the equation to get x value.

Answer:

(1.25, - 5 )

Step-by-step explanation:

Given the 2 equations

- 4x + 3y = - 20 → (1)

4x + 2y = - 5 → (2)

Adding the 2 equations term by term will eliminate the x- term

5y = - 25 ( divide both sides by 5 )

y = - 5

Substitute y = - 5 into either of the 2 equations and solve for x

Substituting into (2)

4x + 2(- 5) = - 5, that is

4x - 10 = - 5 ( add 10 to both sides )

4x = 5 ( divide both sides by 4 )

x = \frac{5}{4} = 1.25

Solution is (1.25, - 5 )

Andrews [41]

Answer: a) 0 and 0.01 b) 0.99 and 1 c) 0.3 d) 0.6

Step-by-step explanation:

Probability is the likelihood that an event will occur. Probability values always lies between 0 and 1 0<P<1

A sure event occurs when the probability is 1 or values pretty close to 1 while probability of an impossible event is 0 or values close to 0. Looking at the given probability values, we can conclude that!

a) 0 and 0.01 = The event is impossible, it would never occur.

b) 0.99 and 1 - The event is certain, it would always occur.

c) 0.3 - The event is highly unlikely, but it will occur once in a while.

d) 0.6 - The event will occur more often than not.
