Answer:
Hence, 16.8 miles is your answer
Answer:
(x+y+z)(a+3)
Step-by-step explanation:
ax+ay+az+3x+3y+3z
=(ax+ay+az)+(3x+3y+3z)
=a(x+y+z)+3(x+y+z)
=(x+y+z)(a+3)
Step-by-step explanation:
let
(-7,-8) =(x1, y1)
and (-6,7)=(x2, y2)
by the formula
d=√(y2-y1) ²+(x2-x1) ²
=√(7+8)²+(-6+7)²
=√15²+1²
= √225+1
= √226
The equation of the line in the slope-intercept form is y=3/2x−2.
The equation of the line in the point-slope form is y−134=3(x−72)/2.
The equation of the line in the point-slope form is y−7=3(x−6)/2
The general equation of the line is 3x−2y−4=0.
Answer:
the solution to the equations is :-
(4,3)
Step-by-step explanation:
here's the solution :-
=》x + 2y = 10
=》x = 10 - 2y
now, plugging the value of x in other equation :-
=》9x - 2y = 30
=》9 × (10 - 2y) - 2y = 30
=》90 - 18y -2y = 30
=》-20y = 30 - 90
=》y = -60 ÷ -20
=》y = 3
now, plugging the value of y in first equation,
=》x = 10 - 2y
=》x = 10 - (2×3)
=》x = 10 - 6
=》x = 4
so, the solution of the system is (4,3)
