Step-by-step explanation:
Answer:
2x + 7
Step-by-step explanation:
0,7 is the y intercept, so plus 7 is a given
0,7 1,9 use rise/run
9-7/1-0 = 2/1
so 2x + 7
60x - 12 = 14x^2 + 14x
Subtract 60x & Combine
-12 = 14x^2+14x-60x
-12= 14x^2-46x
Add 12
0= 14x^2-46x-14
You need one equation for the physical nickels and dimes, which total to 21:
n+d=21
Secondly, you need one equation for the numerical value of those nickels and dimes. We know nickels are worth $0.05 and dime are worth $0.10:
.05n+.1d=1.70
