Y = - 2x + 2<br> 2x + y = 2<br> What is the solution to this ??<br> Pls helpppp
Anna35 [415]

Answer:

Infintely many solutions

Step-by-step explanation:

I'm going to assume that the capital y is equal to the lowerase y

if you subtract y and two from both sides in the second equation you get

-y=2x-2

you then divide by -1 to get it into a normal form

y= -2x+2

this is the same as the first equation, these lines are the same

Tossing 2 fair coins and both landing heads up what would be the fraction for that

The chance of One heads occurring is 1/2.
The chance of the second occurring separately is 1/2 as well. Joint together, it is 1/2x1/2: which is 1/4.

So your answer is 1/4 chance

What are the determinants for solving this linear system? 5x + 3y = 17 −8x − 3y = 9 |A| = |Ax| = |Ay| =
valentina_108 [34]

For this case we have the following system of equations:

5x + 3y = 17\\-8x - 3y = 9

We can Rewrite the system of equations of the form:

Ax = b

Where,

A: coefficient matrix

x: incognita vector

b: vector solution

We have then:

A=\left[\begin{array}{ccc}5&3\\-8&-3\end{array}\right]

x=\left[\begin{array}{ccc}x\\y\end{array}\right]

b=\left[\begin{array}{ccc}17\\9\end{array}\right]

Then, the determinant of matrix A is given by:

|A|=(5)(-3)-(3)(-8)\\

|A|=-15+24

|A|=9

Answer:

The determinants for solving this linear system are:

|A|=9
