Answer: Quadratic
Solution
X=0
X=- 1/3
Equation 1. N+D=500
equation 2 5N+10D=3000
This is for equation 1
N=500-d
Substitute into equations 2 and solve for D
5N+10D=3000
5(500-D)+10D=3000
2500-5D+10D=3000
5D=500
D=100
Lets go back the equation 1
N=500-D
N=500-100
N=400
there are 400 Nickles and 100 Dimes
Answer:
-2
Step-by-step explanation:
X1 Y1 X2 Y2
(-15, 30) (7, -14)
Y2-Y1 = -14-30 = -44 = -2
———————————————
X2-X1 = 7-(-15)= 22 = 1
Answer:
7.
Step-by-step explanation:
Range = highest value - lowest
= 9 - 2
= 7.
