Solve the system of equations below by graphing both equations with a pencil and paper. what is the solution?

B. (2,1)

Step-by-step explanation:

The given system of equation :

Adding equation (1) and (2), we get

Substitute the value of y in the first equation , we get

Therefore, the solution to the given system of equations = (2,1)

to complete this square you have to rotate about the origin 270 degrees clockwise.

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
