Which reflection will produce an image of arst with a
vertex at (2, -3)?
a reflection of arst across the x-axis
r(-1,3) 41
a reflection of arst across the y-axis
a reflection of arst across the line y = x
a reflection of arst across the line y = -x
s(3,-2)
a
t(1.-4)

nswer: a   y-axis

step-by-step explanation:

the answer is d

for problems like this theres an app, its photomath that explains the problem and gives the answer hope i

(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.
