Answer:
y = -1
+ 1
Step-by-step explanation:
The line (a) passing through point (3, -4) is perpendicular to line (b) whose equation is; y = -2 + 
x
The slope of line (b) =
For perpendicular lines, the product of their slopes = -1
So line (a) has a slope of: -1 ÷ = -
Taking another point (x,y) on line (a);
Slope = change in y ÷ change in x
= -
y + 4 = (x - 3)
y = -x + 5 - 4
y = -x + 1
Finally,
y = -1 + 1
m = 4/7, y-intercept (0,1)
Slope-intercept form: y = mx + b where m = slope and b = y-intercept
So equation
y = 4/7 x + 1
Answer
y = 4/7 x + 1
To divide mixed number, convert to improper fractions and divide them
(a/b)/(c/d)=(a/b)(c/d)=(ac)/(bd)
to multiply fractions, multily top by top and bottom by bottom
(a/b)(c/d)=(a times c)/(b times d)
3. Regular
4. Regular
5. Not regular
Answer:
50
Step-by-step explanation:
Given
there is 1 water station at every 0.3 KM
If there are n water stations at every 0.3 KM
then KM covered by them = n*0.3 = 0.3n
given that total KM covered is 15 km
Thus,
0.3n = 15
=> n = 15/0.3 = 50
Thus, there are 50 water stations.
