At first he had 72 then he gave 27 to his neighbor ( 27 subtract 72 = 45) and then he gave 15 to his brother ( 45 subtract 15 = 30)
he had 30 tomatoes left.
The answer is 8:14. this can be simplified to 4:7 (divide by 2).
Answer: The coordinates of the vertex are : (-1,-2)
Step-by-step explanation: To find the x coordinate, we use the formula:
Xv = -b/2a = -6/(2.3) = -6/6 = -1
Replacing x by -1, we write:
y = 3. (-1)^2 + 6. (-1) +1 = 3 - 6 + 1 = -2
