Step-by-step explanation:
y - 5 = 3(x - 1)
y - 5 = 3x - 3
3x - y = -2.
The standard form is 3x - y = -2.
Answer: I hope this helps.
Step-by-step explanation:
Turn f(x) into y so the equation is y=x+2. Now switch their places so it is x=y+2. Now solve for y. The answer is y=x-2.
Derek would have planted the tree 7 years ago. You subtract 36 from 44.75 and get 8.75. This is how much the tree grew since he planted it. Then, you'll divide 8.75 by 1.25 (1 1/4) which tells you how many years it has been since he planted the tree. The final answer is 7 years. Hope this helps!
