Answer:
2069.
Step-by-step explanation:
Let Devyani's age in 2073= x years and y be her fathers age Then:
y = 7x
- and in 8 years time ( 2081) we have:
y + 8 = 3(x + 8)
y = 3x + 24 - 8
y = 3x + 16. Eliminating y from the 2 equations:
7x = 3x + 16
4x = 16
x = 4.
So in 2073 she was 4 years old
Therefore she was born in 2069.
Hello,
Start off by distributing 25 to both x and -4
25 * X = 25x & 25 * -4 = -100
25x - 100 = 30
At this point, we add 100 to both sides so we can get 25 to be seperate from 100.
25x = 130
To get rid of the 25, divide it in both sides:
130/25 = 5.2
The answer would be 5.2
I hope this helps you with your assignment!
Step-by-step explanation:
We have been given that Jeanie stated that the equation of this line best fit for the scatter plot is
.
Let us find the slope of the line of best fit using points (2,7) and (4,6) in slope formula.


We can see that slope of line of best fit is
.
Since the equation of a line written in slope-intercept is in form:
, where m=slope of line, b= y-intercept.
Upon substituting m=
and coordinates of one point in slope-intercept form of equation we will get,



Upon substituting m=
and b=8 in slope intercept form, we will get,

We can see that equation of the line of best fit is
. Jeanie got 1/2 as slope of the line of best fit, which is wrong, therefore, Jeanie's equation of the line of best fit is not correct.
