Hello There!

Follow through these steps:
77 x 4 = 308
76 + 85 + 86 = 247
308 - 247 = 61.

She needs to score 61.

Hope This Helps You!
Good Luck :)

Which point corresponds to the real zero of the graph of y = log3 (x+2) - 1?
brilliants [131]

Answer:

(1, 0 )

Step-by-step explanation:

using the rule of logarithms

log_{b} x = n ⇒ x = b^{n} , then

y = log_{3} (x + 2) - 1

to find the zero let y = 0 , that is

log_{3} (x + 2) - 1 = 0 ( add 1 to both sides )

log_{3} (x + 2) = 1 , then

x + 2 = 3^{1} = 3 ( subtract 2 from both sides )

x = 1

the zero is (1, 0 )
