Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution. x − 3y = −1 4x + 3y = 26 one and only one solution infinitely many solutions no solution find the solution, if one exists. (if there are infinitely many solutions, express x and y in terms of the parameter t. if there is no solution, enter no solution.)

There is only one solution, x = 5 and y = 2.

Step-by-step explanation:

To answer this question, we have to solve this system of equations.

We have that:

x - 3y = -1

4x + 3y = 26

Writing x as a function of y in the first equation, and replacing in the second, we have that:

x = 3y - 1

Replacing in the second

4x + 3y = 26

4(3y - 1) + 3y = 26

12y - 4 + 3y = 26

15y = 30

y = 2

Since we have 15y = 30, y = 2, there is only one solution.

If we had 0y = 0, there would be infinitely many solutions.

If we had 0y = a, a different of zero, there would be no solution.

Solving for x

x = 3y - 1 = 3*2 - 1 = 5

There is only one solution, x = 5 and y = 2.

it has one solution.

Step-by-step explanation:

The given system of equations is expressed as

x − 3y = −1 - - - - - - - - -1

4x + 3y = 26 - - - - - - - - 2

The first step would be to eliminate y by adding equation 1 to equation 2. It becomes

5x = 25

Dividing the left hand side and the right hand side of the equation by 5, it becomes

5x/5 = 25/5

x = 5

Substituting x = 5 into equation 1, it becomes

5 − 3y = −1

3y = 5 +1 = 6

Dividing the left hand side and the right hand side of the equation by 3, it becomes

3y/3 = 6/3

y = 2

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
