Answer:
He drives an extra 4/10 of a mile every day.
Step-by-step explanation:
Looking at our pattern, we see that to get from 84 2/10 to 84 6/10, we would add 4/10.
Similarly, to get from 84 6/10 to 85, we would add 4/10.
This means we add 4/10 of a mile every day.
To check, we can subtract:
85-84 6/10 = 4/10
84 6/10-84 2/10 = 4/10
Intercept of equation 2x + 3y - 6z = 30 is (15, 0, 0) , (0, 10, 0) and (0, 0, -5)
Given equation is:
2x + 3y - 6z = 30
We have to find the intercepts
Intercept are the point where equations cut the x- axis, y- axis and z- axis.
Thus, at x- axis:
y and z both are zero
So substitute y = 0 and z = 0 in given equation
2x + 3(0) - 6(0) = 30
2x = 30
x = 15
Thus at y - axis:
x and z both are zero
So substitute x = 0 and z = 0 in given equation
2(0) + 3y -6(0) = 30
0 + 3y + 0 = 30
3y = 30
y = 10
Thus at z - axis:
x and y are both zero
So substitute x = 0 and y = 0 in given equation
2(0) + 3(0) - 6z = 30
-6z = 30
z = -5
Thus, intercept of equation 2x + 3y - 6z = 30 is (15,0,0) ,(0,10,0) and (0,0,-5)
