Without graphing, classify the following system as independent, dependent, or inconsistent. y=-3x+4 and 6x+2y=8

forsale [732]

Answer:

Dependent

Step-by-step explanation:

$y=-3x+4$ and $6x+2y=8$

Lets solve the second equation for y and then substitute it in first equation

$6x+2y=8$

Subtract 6x on both sides

$2y=-6x+8$

Divide by 2 on both sides

$y=-3x+4$

Now we plug it in first equation for y

$-3x+4=-3x+4$

Add 3x on both sides

$4=4$

Both sides are same, they are equal. the system has infinite solutions.

They are said to be dependent

A black shoe is selected at random from a bin of 6 black shoes and 4 brown shoes and not replaced. What is the probability that

MrMuchimi

Hello,

If 1 black shoe is selected from a bin of 6 black shoes and 4 brown shoes and not replaced, then there are 5 black shoes and 4 brown shoes remaining. To find the probability that the a black shoe will be selected out of 5 black shoes and 4 brown shoes, we divide the number of black shoes over the total number of shoes (Each selection of a shoe is independent).

Doing this, we get 5 / (5+4) = 5/9 ≈ 0.55
The probability that a second shoe selected will be black is 0.55.

Hope this helps!

If sin(1/x^2+1) is an anti derivative for f(x), then what is the limit of f(x)dx from 1 to 2?

liubo4ka [24]

By the fundamental theorem of calculus,

$\displaystyle\int_1^2f(x)\,\mathrm dx=\sin\dfrac1{2^2+1}-\sin\dfrac1{1^2+1}$
