Solve using substitution y=3x-5 2x+5y=-42

Paul [167]

Answer:

Solution point is (-1,-9)

Step-by-step explanation:

Put the value of y in the first equation into the second equation.

2x + 5(3x - 5) = - 42 Remove the brackets on the left
2x + 15x - 25 = - 42 Combine like terms on the left
17x - 25 = - 42 Add 25 to both sides
17x - 25 + 25 = - 42 + 25 Do the addition
17x = - 17 Divide by 17
17x/17 = -17/17 Do the division
x = - 1

=======

Solve for y

y = 3x - 6
x = -1
y = 3(-1) - 6
y = -3 - 6
y = - 9

stich3 [128]

Given:

Given that there are 10 marbles in a bag. 4 are blue, 3 are black, 2 are white and 1 is red.

The marbles are selected by not replacing the drawn ones.

We need to the probability of selected a black marble and then a white marble without replacement.

Probability:

Let B denote the black marble.

Let W denote the white marble.

The probability of selecting a black marble is $P(B)=\frac{3}{10}$

The probability of selecting a white marble without replacement is $P(W)=\frac{2}{9}$

The probability of selecting a black marble and then a white marble without replacement is given by

$P(B \ and \ W)=P(B) \cdot P(W)$

Substituting the values, we get;

$P(B \ and \ W)=\frac{3}{10} \cdot \frac{2}{9}$

$P(B \ and \ W)=\frac{6}{90}$

$P(B \ and \ W)=\frac{1}{15}$

Thus, the probability of selecting a black marble and then a white marble without replacement is $\frac{1}{15}$
