Answer:
(4,8)
Step-by-step explanation:
Left 2 units means subtract 2 from the x axis and up 4 units means add 4 to the y value, so the point would be (4,8).
Answer:
Step-by-step explanation: let the first number be x and the second number be y
according to the condition given
x+y=21
3x-y=43
using elimination method
3x+3y=63
3x-y=43
subtacting both the equations
4y=20
y=20/4
y=5
substituting value of y in eq 1
x+5=21
x=21-5
x=16
therefore x=16 and y=5
the two numbers are 16 and 5
19/18 is the correct answer.
Answer:
0.142 cm/yr
Step-by-step explanation:
An <em>average</em> is the sum of all the measurements divided by the number of measurements.
If there was a measurement each year, there were 175 measurements, and their sum is 24.8 cm.
Average movement = 24.8/175
Average movement = 0.142 cm/yr
The land moved an average of 0.121 cm each year
