Answer:
x = -3
y = -1
Step-by-step explanation:
in the given question :-
=》x - 4y = 1
=》x = 4y + 1
now replacing the value of x as ( 4y + 1 ) in equation (2)
=》3x + 2y = -11
=》3 (4y + 1) + 2y = -11
=》12y + 3 + 2y = -11
=》14y = -11 - 3
=》y = -14 ÷ 14
=》y = -1
now, putting the value of y in equation (1)
=》x - 4y = 1
=》x - ( 4 × -1 ) = 1
=》x + 4 = 1
=》x = 1 - 4
=》x = -3
To solve a Linear equation we need to find the slope:
-4-1 / -2-8 =1/2
now that we have the slope we can find our x and y
y-1=1/2(x-8)
y=x/2-3
Distance÷time
440÷8= 55
Therefore he needs to drive at the speed of 55 miles/hour
Investment: cost of her education + salary as sales clerk during two years
Investment = 18,000 (2) + 20,000 = 36,000 + 20,000 = 56,000
Time to recover investment = 56,000/35,000 = 1.6
In less than two years, after she starts to work Niah will have recoverd her investment.
