If f = price of filing cabinet and c = price of cupboard we can make up the equation

2f + 4c =800

we also know that f = 3c, so can substitute that into equation

2(3c) +4c = 800

6c + 4c = 800

10c = 800

<u>c = 80</u>

<u>f = 240</u>

<span>Consider a angle â BAC and the point D on its defector Assume that DB is perpendicular to AB and DC is perpendicular to AC. Lets prove DB and DC are congruent (that is point D is equidistant from sides of an angle â BAC Proof Consider triangles ΔADB and ΔADC Both are right angle, â ABD= â ACD=90 degree They have congruent acute angle â BAD and â CAD( since AD is angle bisector) They share hypotenuse AD therefore these right angle are congruent by two angle and sides and, therefore, their sides DB and DC are congruent too, as luing across congruent angles</span>

6x+4y=12 into y=my+b
kirza4 [7]
6x + 4y = 12...subtract 6x from both sides
4y = -6x + 12 ...divide both sides by 4
(4/4)y = (-6/4)x + 12/4...reduce
y = -3/2x + 4 <== y = mx + b
