Answer:
( -0.5 , 6.5 )
Step-by-step explanation:
(3,51)(5,59)
slope = (59 - 51) / (5 - 3) = 8/2 = 4
y = mx + b
slope(m) = 4
(3,51)...x = 3 and y = 51
sub and find b, the y int
51 = 4(3) + b
51 = 12 + b
51 - 12 = b
39 = b
so ur equation is : y = 4x + 39...but u need it in standard form
y = 4x + 39
-4x + y = 39
4x - y = -39 <==== this is ur equation...x = number of hrs and y = total velocity
====================
ur x axis is the number of hrs
ur y axis is total velocity in km
y = 4x + 39......slope = 4.....y int = (0,39)....x int is (- 9.75,0) or -9 3/4 for graphing purposes)....so start at (-9.75,0)...and since the slope is 4, go up 4 and to the right 1....plot that...then up 4 and to the right 1...plot that...u will cross the y axis at (0,39)....and just connect ur plotted points and u have ur line......or what u can do since it is asking for the first 6 hrs....sub in 1 for x and solve for y....then sub in 2 for x and solve for y...keep doing this up till 6 and u will have ur line up till 6 hrs
Answer:
The mean is 4
Step-by-step explanation:MRK ME BRAINLIEST PLZZZZZZZZZZZZZz
ita 4 because first you add up the 10,3,2,5,0. and then it equals 20 and then divided and get the mean which is 4
Hello
First you have to remove your parenthesis and since there is a “+” in front of the parenthesis, the expressions remain the same. So:
9.88+6.7-x = 2,6
Now, you have to add the numbers. So:
16.58-x = 2,6
Next, you have to move the constant (x) to the right and change its sign since it changes side. So:
-x = 2,6-16,58
Now, calculate the difference:
-x = 13,98
And lastly, change the signs on both sides of the equation since - + - equals +. So:
x = 13,98
Hope you found this helpful
Have a good day
