She travels a mile in 6.6 minutes and 30/4 is 7.5. 6.6 repeating is lower than 7.5 which means it is faster.
We want h(x) = g(x) - f(x).
h(x) = -2x + 9 -(6x - 5)
h(x) = -2x + 9 -6x + 5
h(x) = -8x + 14
The square root of 48 simplified is 4 sqrt 3.
Answer:
The graph represent a scatter plot between variable A on the horizpntal line and the variable B on the vertical line.
A line of best fit is a straight line drawn through the maximum number of points on a scatter plot balancing about an equal number of points above and below the line.
As shown by graphinf a line through the maximum number of points, balancing about an equal number of points above and below the line, we can deduce that:
<u>The line of best fit drops from left to right, so the variables have a negative correlation. </u>
For Right angled triangle area
A=ab/2
(2x-2)(4x+2)/2
(8x^2+4x-8x-4)/2
(8x^2-4x-4)/2 take common term 2
2(4x^2-2x-2)/2
So A=4x^2-2x-2
