Answer:

Correct choice is D

Step-by-step explanation:

Given the system of two equations:

\left\{\begin{array}{l}4x+y=8\\6x-9y=12\end{array}\right..

Fro mthe first equation

y=8-4x.

Substitute into the second equation 8-4x instead of y:

6x-9(8-4x)=12.

Note that 8-4x=-4x+8, then the second equation will take look

6x-9(-4x+8)=12.

Each time, you take out one ball from the box and then put it
melamori03 [73]

Answer:

40/3087

Step-by-step explanation:

First, we need to count the number of each type of numbered ball.

Ball Counts: 1 - 5 balls; 2 - 2 balls; 3 - 1 ball; 4 - 2 balls; 5 - 4 balls; 6 - 3 balls; 7 - 1 ball; 8 - 2 balls; 9 - 1 ball, there are then a total of 21 balls

Next, you need to find the probability of each event.

Get less than 4

p(<4) = (5+2+1)/21

p(<4) = 8/21

Get less than 2

p(1) = 5/21

Get exactly 6

p(6) = 3/21

p(6) = 1/7

Next, we need to find the probability of all three events by multiplying the probabilities together.

p(all three) = (8/21)*(5/21)*(1/7)

p(all three) = 40/3087

The probability of all three events occurring is 40/3087.

Answer:

The correct option is 4.

Step-by-step explanation:

It is given that figure ABCD is transformed to figure A′B′C′D′.

The vertices of ABCD are A(1,1), B(3,3), C(4,2) and D(4,1).

The vertices of A'B'C'D' are A'(1,-3), B'(3,-1), C'(4,-2) and D'(4,-3).

It is clear that the figure translate 4 units down and the rule of translation is

Translation is a rigid transformation, it means image and preimge are congruent.

Since ABCD is translate 4 units down to make A′B′C′D′, therefore

Congruent part of congruent figures are congruent.

                 

Therefore the correct option is 4.

I Hope It's Helpful :)
