d = dimes
q = quarters
d=10+q
0.25q +0.10d = 3.45
0.25q + 0.10(10+q) = 3.45
0.25q + 1 +0.10q =3.45
0.35q=2.45
q = 2.45/0.35 = 7
d = 10+7 =17
0.25*7=1.75, 17*0.10 = 1.70, 1.75+1.70 = 3.45
she has 7 quarters and 17 dimes for a total of 24 coins
Yes, it's all right. There's no fault
You can probably look up a answer key for that worksheet. ;)

Answer:
{ - 33, - 23, 2, 12 }
Step-by-step explanation:
Given
f(x) = 5x - 13 with domain { - 4, - 2, 3, 5 }
To obtain the range substitute the values of x from the domain into f(x)
f(- 4) = 5(- 4) - 13 = - 20 - 13 = - 33
f(- 2) = 5(- 2) - 13 = - 10 - 13 = - 23
f(3) = 5(3) - 13 = 15 - 13 = 2
f(5) = 5(5) - 13 = 25 - 13 = 12
Range is { - 33, - 23, 2, 12 }
