Answer:

D.

Step-by-step explanation:

The solution is where the lines intersect which is at the point (3,2).

So the answer is Option D.

The point (3,2) satisfies both equations.

Answer:  The correct option is

(D) (3, 2), because both lines pass through this point.

Step-by-step explanation:  Given that the two lines A and B are represented by the following equations :

Line A: y = x − 1  

Line B: y = −3x + 11

We are to select the correct option that shows the solution to the above system of equations with reason.

The solution to the above system of linear equations will be the point through which both the lines A and B passes.

Now, comparing the values of y from both the equations, we get

x-1=-3x+11\\\\\Rightarrow x+3x=11+1\\\\\Rightarrow 4x=12\\\\\Rightarrow x=\dfrac{12}{4}\\\\\Rightarrow x=3.

And, from first equation, we get

y=x-1=3-1=2.

Thus, the required solution is (3, 2) because both the lines pass through this point.

Option (D) is CORRECT.

Jamie has a bag containing purple, pink, yellow, and blue marbles. There are a total of 40 marbles in the bag. Jamie randomly se
Ad libitum [116K]

Answer:

1 pink marble

Step-by-step explanation:

If Jamie selected 10 times the pink marble in a total of 420 tries, we can assume that the proportion of pink marble in the total number of marbles is:

10 / 420 = 1/42

So to predict a good number of pink marbles in the total 40 marbles, we just need to multiply the 40 marbles by the proportion found above:

pink marble = 40 * (1/42) = 0.9524

As this number needs to be a whole number, a good assumption is that there is 1 pink marble in the 40 marbles.
