Answer:

see the explanation

Step-by-step explanation:

we have

f(x)=x^2

This is the equation of a vertical parabola open upward

The vertex represent a minimum

The vertex is the point (0,0)

The general shape of a parabola is the shape of a "pointy" letter "u," or a slightly rounded letter, "v."

If the function is negative

then

f(x)=-x^2

This is the equation of a vertical parabola open downward

The vertex represent a maximum

The vertex is the point (0,0)

see the attached figure to better understand the problem

Answer please show steps please
erik [133]

Answer:

25 girls

Step-by-step explanation:

Let

x denote number of boys

and

y denote number of girls

According to the statement that total 45 people came,

x+y = 45      => Eqn 1

And total paid amount was 175

So,

5x + 3y = 175    => Eqn 2

For solving, We will use the substitution method

So, from eqn 1

x = 45-y

Putting value of x in eqn 2

5(45-y) +3y = 175

225 - 5y + 3y = 175

-2y+225 = 175

-2y = 175-225

-2y = -50

2y = 50

y = 25

Putting y =25 in eqn 1

x+25 = 45

x = 45 - 25

x = 20

As y= 25

So, 25 girls came to the dance ..

Len and Faye live 54 miles apart. At the same time, they start biking toward each other on the same road. Len's constant rate is
Aloiza [94]

Answer:

Step-by-step explanation:

Len and Faye live 54 miles apart. At the same time, they start biking toward each other on the same road. Len's constant rate is 7 mph and Faye's is 11 mph. How many hours will it take them to meet? [Remember: D = (r)(t)]

 Answer – 3 hours

 D = (r)(t), Where

‘D’ is the distance covered

‘r’ is the approach rate

‘t’ is the total time spent

 Distance covered, ‘D’ =  miles

Approach rate, “r” = mph + mph 7+11

r =  18

t is unknown

 Solving for t,

 D = (r)(t)

54 = 18t

t = 54/18

t = 3 hours
