Answer:
Step-by-step explanation:
81 + 18 = 99
- A. 9(9 + 2) = 99, correct
- B. 9(9 + 9) = 198 ≠ 99
- C. 9(9 + 3) = 108 ≠ 99
- D. 3(27 + 18) = 135 ≠ 99
The first coordinate is given the letter x and the second coordinate is given the letter y. Thus, we have that we need to substitute in the formula of the transformation 2 for x and -1 for y. Hence, we have that the image of A is given by: T(A)= (2-5, -1+3)= (-3, 2).
The number is -4
-3n + 8 = 20
-3n = 12
n = -4
Answer:
a) f(n) = 11 + f(n - 1)
Step-by-step explanation:
f(2) = 11 + 4 = 15
f(3) = 11 + 15 = 26
f(4) = 11 + 26 = 37
f(5) = 11 + 37 = 48
I'm pretty sure it would be d
