The number closest to 65 is 8.
(61 square is 8)
F(4) value is 6.
I believe it would work like this:
f(x) is being turned into f(4), so 4 would equal x. Put 4 into the equation 3x-6, and you get 12-6, which gives you 6. So the value of f(4) is 6. I hope this helps!
Answer:
large = 18 3/4 = 18.75
small = 13/2 = 6 1/2 = 6.5
Step-by-step explanation:
Let l = the weight of large boxes
s = weight of small boxes
2 large and 3 small weights 57
2l+3s = 57
6 large and 5 small wights 145
6l+5s = 145
Multiply the first equation by 3
3(2l+3s) = 57*3
6l +9s =171
Subtract the second equation
6l +9s =171
-6l -5s = -145
-----------------------
4s =26
Divide each side by 4
4s/4 = 26/4
s = 26/4 = 13/2
Substitute this into the first equation
2l +3s = 57
2l + 3(13/2) =57
Multiply by 2 to get rid of the fractions
2(2l + 3(13/2)) =57*2
4l + 39 = 114
Subtract 39 from each side
4l +39-39 = 114-39
4l =75
Divide by 4
4l/4 = 75/4
l = 75/4 = 18 3/4
Answer:
Option (4)
Step-by-step explanation:
Slope a line passing through two points 
and 
is given by,
m = 
Since, blue line is passing through two points (-4, -2) and (0, 4),
Slope of the blue line = 
= 
Similarly, green line is passing through two points (-4, 1) and (0, -2),
Slope of the green line = 
= 
Since, 
Neither these slopes are opposite reciprocals.
Therefore, both the lines are neither parallel nor perpendicular.
Option (4) will be the correct option.
1. I did 9x8 since you usually work 8 hours a day but did not give answer, so I add or subtracted 0.5 to 8.
2. i did 9*7.5=67.5 , keep in mind that he worked for 11 hrs that day so 11-7.5=3.5 hours left
3. then I subtracted 67.5 from 114.75 and got 47.25
4. I divided 3.5 by 47.25 and got 13.5
