Solve using the substitution method 2x+3y=1 y=x-8
QveST [7]
Subsitute

y=x-8
since y=x-8, subsitute x-8 for y

2x+3(x-8)=1
distribute (a(b+c)=ab+ac)
3(x-8)=3x-24

2x+3x-24=1
combine like terms
5x-24=1
add 24 to both sides
5x=25
divide 5
x=5
subsitute
y=x-8
y=5-8
y=-3

x=5
y=-3 is solution
in (x,y) forom
(5,-3) is the solution

A train travels a distance of 60 km at uniform speed. If the speed of the train was reduced by 10 kmh-1, the time taken to trave
tester [92]

Answer:

<u>Initial</u><u> </u><u>speed</u><u> </u><u>is</u><u> </u><u>3</u><u>2</u><u> </u><u>m</u><u>/</u><u>s</u>

At uniform speed, acceleration is 0, (a = 0).

When speed reduced, (v - u) = 2.78 ms-¹, t = 1800 sec, s = 60 ,000 metres.

From first equation of motion:

{ \boxed{ \bf{v = u + at}}} \\  { \tt{(v - u) = at}}

substitute:

{ \tt{2.78 = (a \times 1800)}} \\ { \tt{acceleration = 0.0015 \:  {ms}^{ - 2} }}

from second equation of motion:

{ \boxed{ \bf{s = ut +  \frac{1}{2} a {t}^{2} }}}

substitute:

{ \tt{60000 = 1800u + ( \frac{1}{2} \times 0.0015 \times  {1800}^{2})  }} \\ { \tt{1800u = 57570}} \\ { \tt{u = 32 \: m {s}^{ - 1} }}
