VikaD [51]3 years ago
8 0

Answer:

13

Step-by-step explanation:

s(x) = 3x + 5 \\ t(x) =  - x + 3 \\  \\ \implies t(s(x)) =  - (3x + 5) + 3 \\  \\\implies t(s(x)) =  - 3x  - 5 + 3 \\  \\\implies t(s(x)) =  - 3x  - 2 \\  \\ \implies t(s( - 5)) =  - 3( - 5)  - 2 = 15 - 2\\\\\implies t(s( - 5))= 13

Kyle asks his friend Jane to guess his age and his grandmother’s age. Kyle says his grandmother is not more than 80 years old. H
motikmotik
The incorrect inequality is g > 80. The symbol ">" means greater than. So g > 80 would translate to meaning Kyle's grandmother is greater than 80. However, the problem states that his grandmother is not more than 80, meaning she is either 80 or younger. So the inequality should be g ≤ 80, or Kyle's grandmother is less than or equal to 80 years of age.
