Answer: it will take 0.33 years for the heights to be the same.
Step-by-step explanation:
Let x represent the number of years it will take for both trees to be the same height.
Type A is 7 feet tall and grows at a rate of 2 inches per year. This means that the height of the tree after x years would be
2x + 7
Type B is 2 feet tall and grows at a rate of 17 inches per year. This means that the height of the tree after x years would be
17x + 2
For the heights to be the same, the number of years would be
17x + 2 = 2x + 7
17x - 2x = 7 - 2
15x = 5
x = 5/15
x = 0.33 years
Answer:
m=-4 slope is -4
Step-by-step explanation:
A.It is less than -7 5/8
because multiplying by a number less than 1
gives a smaller number.
B.It is greater than -4
because 0.36×(7 5/8)
0.36*(7 5/8) is less than 1/2 * 8
C.It equals -7 5/8
because 36/36
equals 1
, and 1
times any number equals that number.
D.It equals 0
because 0.36
rounded to the nearest whole number is 0
, and 0
times any number is 0.
