Determine the best method to solve the system of equations. Then
solve the system. x - 3y = 25 and 2x + y = 64. can you please help!!!!!

Answers

Answer 1

Answer:

(31, 2); Substitution.

Step-by-step explanation:

x - 3y = 25

Use SUBSTITUTION by setting everything in the above equation equal to x...

x = 3y + 25

2(3y +25) + y = 64

6y + 50 + y = 64

7y + 50 (-50) = 64 (-50)

7y = 14

y = 2

Then, substitute y = 2 into the original equation.

x - 3(2) = 25

x - 6 = 25

x = 31

(x, y) = (31, 2)

Answers

Answer:

This equation has two solutions.

1 solution is: x - 1

Solution #2 is : x - 7

Step-by-step explanation:

1. Move the constant to the left. We end up with x^2 - 8x +7 = 0

2. Rewrite the expression: x^2 - x - 7x + 7 = 0

3. Factor the expressions: x * (x-1) -7(x-1) = 0

4. Separate into possible cases : (x-1) * (x-7) = 0

5. Solve the equation(s): x-1 = 0

                                         x-7 = 0

6. Possible solutions are as follows: x-1 OR x-7

calculate the coefficient b in the function f (x) = - x + b for which it holds that the graph passes through the point (-1,3)
Need if fast!

Answers

Answer:

b = 2

Step-by-step explanation:

For the graph to pass through the point, we have it that the coordinates of the point will work in the equation of the line

Hence, by substituting the x value, we can get the y value and by substituting the y value, we can get the x value

where f(x) is same as y in this case

Thus, we have it that;

3 = -(-1) + b

3 = 1 + b

b = 3-1

b = 2

Ok, so you would want to simplify both sides of the equation

(-1/3)(-12) + (1/3)(-12c)=-20 (here you distribute)

4+4c=-20

Then, subtract 4 from both sides

4c+4-4=-20-4

4c=-24

Then divide both sides by 4

4c/4=-24/4

c=-6
