Answer:

  46

Step-by-step explanation:

The value 529 is 23·23, so Bert must have had 23 friends bring him 23¢ each.

The way 23¢ can be made with 6 coins is ...

  • 3 pennies
  • 2 nickels
  • 1 dime

So, Bert collecte 23 × (2 nickels) = 46 nickels.

On a coordinate plane, a dashed straight line has a negative slope and goes through (0, 3) and (2, negative 1). Everything to th
Nimfa-mama [501]

Answer:

The answer to your question is    y < -2x + 3

Step-by-step explanation:

See the graph below

Process

1.- Find the slope

   m = \frac{y2 - y1}{x2 - x1}

Substitution

   m = \frac{-1 - 3}{2 - 0}

   m = \frac{-4}{2}

   m = -2

2.- Find the equation of the line

   y - y1 = m(x - x1)

Substitution

  y - 3 = -2(x - 0)

Simplify and solve for y

  y - 3 = -2x

  y = -2x + 3

3.- Write the inequality

As the left area of the plane is shaded the inequality must be

 y < -2x + 3
