ASAP PLEASE HELP Find the​ x- and​ y-intercepts of the line that passes through the given points.
Umnica [9.8K]

Answer:

Set it up using the slope from the two points. (c - (-5))/3 - 1 = slope = (c + 5)/2. Now put this into slope intercept since they give you the y intercept of 7. y = x*(c + 5)/2 + 7. Now put in the point, (1,-5). -5 = 1*(c+5)/2 + 7. Subtract 7 from both sides. Now multiply through and you can solve for c.

Alex has 84 quarters and nickels worth a total of $17.80.
Hunter-Best [27]

The equation which can be used to find the number of quarters and nickels is; n + q = 84, 0.05n + 0.25q = 17.80.

<h3>Quarters and nickels</h3>

  • Total coins = 84
  • Total value = $17.80

let

  • Number of quarters = q
  • Number of nickels = n

n + q = 84

0.05n + 0.25q = 17.80

From equation (1)

n = 84 - q

Substitute into (2)

0.05n + 0.25q = 17.80

0.05(84 - q) + 0.25q = 17.80

4.2 - 0.05q + 0.25q = 17.80

- 0.05q + 0.25q = 17.80 - 4.2

0.20q = 13.60

q = 13.60 / 0.20

q = 68

Substitute q = 68 into

n + q = 84

n + 68 = 84

n = 84 - 68

n = 16

Therefore, the number of quarters and nickels are 68 and 16 respectively.

Basically, you would just have to do two, three times.

Very time when you get the hang of it !!
