A triangle is translated by using the rule (x, y) right-arrow (x minus 4, y + 1). Which describes how the figure is moved? four units left and one unit down
four units left and one unit up
one unit right and four units down
one unit right and four units up

what level of math? also i don't need to be paid if i can you.

step-by-step explanation:

b. b < 1 might be the correct answer

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
