Answer:
4) 95*.6=57
5) 60-18=42 42/60=70%
6) 26800-5500=21300 21300*.15=3195$
9)9200*.07=644 644+800=1444
3) 36*.75=27ft
discriminant= b^2-4ac= (-2)^2-4(4)(9)= -140<0
since discriminant <0, graph is always positive, x has no real roots
X=amount of money Ofeila hasx-$12=(1/5)xLet's eliminate the fractions by multiplying both sides by 5...5(x-$12)=(5)(1/5)x5x-$60=xLet's subtract 5x from both sides...-5x+5x-$60=x-5x-$60=-4xLet's divide both sides by -4...(-$60)/(-4)=(-4x)/(-4)$15=x -< AnswerLet's check our work...x-$12=(1/5)x$15-$12=(1/5)($15)$3=$3
At= -5(1/2)
at= -2.5
v= u + at
v= 2 + (-2.5)
v= -0.5
