Rosie bought a car for £4000 3 years later, she sells it for £1400
What is the percentage loss that Rosie has made?

65%

Step-by-step explanation:

Given data

Cost price= £4000

Selling price=  £1400

% loss= cost price-selling price/cost*100

% loss= 4000-1400/4000*100

% loss= 2600/4000*100

% loss= 0.65*100

% loss= 65%

Hence the %loss is 65%

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
