A system of two linear equations is shown below 2.0 + 3y = 6
-2 + 4y = 8
Henrietta claims that replacing the equation 2x + 3y = 6 with a different equation sometimes produces a
system with the same solutions. Select three equations that can be used to support Henrietta's claim.
A
2 + y = 14
B
2x - 8y = -16
С
4x - 5y = -10
D
-2 + 15y = 30

step-by-step explanation:

5 + 8 +7 + 4 + 0 +1 = 25

step-by-step explanation:

(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.
