Step-by-step explanation:
2x+ y = 11 ----------------(I)
y = 11 - 2x --------------------(II)
Multiply the whole equation by 2
x - 10y = 16 --------------------(III)
Substitute y = 11- 2x in equation (III)
x - 10(11 - 2x) = 16
x - 110 + 20x = 16
21x - 110 = 16
21x = 16 +110
21x = 126
x = 126/21
x = 6
Plugin x = 6 in equation (II)
y = 11 - 2*6
y = 11 - 12
y = -1
Answer:
Step-by-step explanation:
Let represent the number of monitors sold.
Given:
is the number of years since 1990.
So, for the year 1990, .
For the year 2000, 10 years passed. So, .
Now, monitors sold in 1990 are 150. So, at
Monitors sold in 2000 are 900. So, at
Thus, the two points are and
.
The slope of a line with points and
is given as:
Slope,
For the points and
, the slope is given as:
Slope,
Now, the y-intercept is the point where . So, the point
has
value as 0.
So, the y-intercept is 150.
Equation of a line in slope-intercept form is given as:
Where, is the slope and
is the y intercept.
Here, and
.
Therefore, the equation that represents the above data is given as:
