Answer:
0.9 hours
0
the nature of line is pure liner
Step-by-step explanation:
The attached graph is the drawn graph of given data
i) A teenager would spend exercising in one day if they spent 0.25 hours on social media.
0.9 hours
According to the graph if you locate the 0.25 hour on x-axis and draw perpendicular the will intersect the line on the value of y-axis is = 0.9 hours
ii) if they spent 1.38 hours on social media the corresponding value of exercising per day is approx 0
iii) Yes it has the best fit value of corresponding values between two. which is also reasonable in the all cases. the nature of line is pure liner.
Answer:
Step-by-step explanation:
2p/2 = 2x+7
1) 2x+7 -x - 5 =
width = x + 2
2) 2p/2 = 21 in
x + 5 + x + 2 = 21
2x = 14
x = 7
lenght = 7 + 5 = 12 in
width = 7 + 2 = 9 in
3 )
A = (x+5)(x+2)
4)
A = 12 x 9 = 108
Answer:
The area is 252
Step-by-step explanation:
Answer:
To factor something out you've got to divide, so you would take 5x+40 and divide it all by 5
So, 5x/5= 1x
And, 40/5= 8
Your answer is now x+8 when factored
Answer:
y= 7x-73
Step-by-step explanation:
the equation form is y=mx+c where m is the slope and c a constant
m= (25-(-10))/14-9 = 35/5 = 7
so y= 7x+c
replace x and y by 14 and 25 respectively
25 = 7*14+c
c= 25-7*14
c = -73
so y= 7x-73
