Hope this helps
X = number of dimes
y = number of quarters
---
10x + 25y = 2565
y = x + 20
---
put the system of linear equations into standard form
---
10x + 25y = 2565
x - y = -20
---
copy and paste the above standard form linear equations in to this solver:

solution:
x = 59
y = 79
Answer:
6x2 + 23x + 7 = 0
Factorization:
(2x + 7)(3x + 1) = 0
Solutions based on factorization:
2x + 7 = 0 ⇒ x1 = −7
2
= −3.5
3x + 1 = 0 ⇒ x2 = −1
3
≈ −0.333333
Extrema:
Min = (−1.916667, −15.041667)
Step-by-step explanation: hope this helps
