The answer for this question is $3.92
(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
Hello :
4 - 2/5 = 20/5 -2/5 =18/5 =(<span>√(18/5))²</span>
It is not a tough but a little tricky question. here all the in formations are provided for finding the required answer.The person in the question went to have dinner and his bill was 120. He additionally paid a tips of 21.60. Now the thing that needs to be found is the percentage of tips the person leaves behind.
Let us assume that the percentage of tips left behind = x%
Then we can write the equation as:
120 * (x/100) = 21.60
120x/100 = 21.60
12x/10 = 21.60
12x = 21.60 * 10
12x = 216
x = 216/12
= 18
So the person left 18% tips.
