Answer:

  • 15 nickels
  • 3 dimes

Step-by-step explanation:

Let d represent the number of dimes Molly has. Then she has 18-d nickels, and the total value (in cents) of her coins is ...

  5(18 -d) +10d = 105

  5d +90 = 105 . . . . . . simplify

  5d = 15 . . . . . . . . . . . subtract 90

  d = 3 . . . . . . . . divide by 5; number of dimes

  18-d = 15 . . . . . number of nickels

Molly has 3 dimes and 15 nickels.

Graph the line -1 passing through the point (-4,5)​
Dennis_Churaev [7]

Answer:

Step-by-step explanation:

If you want to find the equation of line with a given a slope of which goes through the point (-4,5), you can simply use the point-slope formula to find the equation:

---Point-Slope Formula---

where is the slope, and is the given point

So lets use the Point-Slope Formula to find the equation of the line

Plug in , , and (these values are given)

Distribute  

Multiply and to get

Add -1 to both sides to isolate y

Combine like terms and to get the answer

So the equation of the line with a slope of which goes through the point (-4,5) is:

which is now in y=mx = b form where the slope is m=-4/5  and the y-intercept is b=1
