Answer:
1) "Most certainly, do you like your math class?"
2) "Sometimes it is difficult but I just request extra help."
3) "For sure! As long as you keep trying, your efforts will pay off. It was nice talking to you."
Let the height of the tree be x, then
18 inches / 3 feet 9 inches = x / 21 feet 3 inches
18 inches / 45 inches = x / 255 inches
45x = 18 x 255 = 4590
x = 4590 / 45 = 102
Therefore, the tree is 102 inches = 8 feet, 6 inches tall
Answer: -12
Step-by-step explanation: because -7- 5= -12
Subtract 3x from both sides:
-6y = -3x + 6
divide both sides by -6 to get y by itself:
y = 1/2x - 1
function notation is rewriting y as a function:
f(x) = 1/2x -1
