Explain how you can determine that the following system has one unique solution – without actually solving the system. 2x+y=4 , 2y=6-2x

Both equations has different slope , so the system of equation have one unique solution.

Step-by-step explanation:

,

To determine that the system of equation has unique solution, we need to find out the slope.

To find slope, we write the equation in the form of y=mx+b

Where m  is the slope and b is the y intercept

Subtract 2x on both sides

here, m= -2 is the slope

Divide both sides by 2

Slope m = -1

Both equations has different slope , so the system of equation have one unique solution.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
