Answer:   has a maximum

              the maximum is  11

Step-by-step explanation:

f(x)= -5x^2-10x+6

the function f(x)= ax^2+bx+c=0  has a<0  so the equation has a maximum

I know V has the coordonate x=-b/2a,  and y=-(b^2-4ac)/4a

b^2-4*a*c= (-10)^2-4*(-5)*6=100+120=220

so -b/2a=-(-10)/-2*5=+10/-10=-1 and

    -(b^2-4ac)/4a=-220/4*(-5)=-220/-20=22/2=11

so  V( -1, 11)

and  the maximum is  11

Jlenok [28]

Answer:

number of dimes is 8

number of quarters is 15

Step-by-step explanation:

let 'd' = number of dimes

let 'd+7' = number of quarters

.10d + .25(d + 7) = 4.55

.10d + .25d + 1.75 = 4.55

.35d = 2.80

d = 8

q = 7 + 8
