Jada has pennies and nickels that add up to more than 40 cents. She has fewer than 20 coins altogether. If x is the number of pennies and y is the number of nickels, write a system of inequalities that represents how many pennies and nickels that Jada could have in this form(example): 3x+4y>6and2x-3y<5. Note that there is no space between characters in the answer.

  x+y<20andx+5y>40

Step-by-step explanation:

The inequality for the number of coins is ...

  x + y < 20

The inequality for the value of the coins is ...

  x + 5y > 40

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
