Answer: x < 5
Step-by-step explanation: 4x + 40 < 60
3x+y=19
y=19-3x and y=x+3, at a solution both x and y are equal so we can say y=y:
19-3x=x+3
19-4x=3
-4x=-16
x=4, and since y=x+3
y=7 so the solution is the point:
(4,7)
Answer: F. is a linear relation.
Step-by-step explanation:
Answer:
The continents moved by 1.905 centimeters each year.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
In the past 100 years, scientists measured the movement of the continents to be 190.5 centimeters. How much it moved in a year?
100 years - 190.5 centimeters.
1 year - x centimeters
The continents moved by 1.905 centimeters each year.
Answer:
y = 16
Step-by-step explanation:
y = 11 - x
of x is -5, subtitute it into the equation
y = 11 - (-5)
y = 11 + 5
y = 16
