Answer: y = 7
explanation: 6y = 6y + 7
y =
7/3 is represented by a non terminating decimal (2.333...)
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.
Answer:
No, they aren't proportional.
Step-by-step explanation:
To simplify a ratio, you have to find the common greatest factors between both variables on each side. In this case, 25:16 is the simplist form and could never be minimized to 5:4.
Lawn table
5 * 8 = 40
6 * 8 = 48
8 * 8 = 64
7 * 8 = 56
Theme park ratio 1:9
Means 1 hr is $9.00
5 45
6 54
8 72
She makes $40 for 5 hrs mowing lawns and $45 for 5 hrs at the theme park. She makes $5 more at the theme park for 5 hours of work.
