Answer:
when its a linear equation
Step-by-step explanation:
The 2 is in the ten million’s place
D=dimes
q=quarters
d + q = 20
.10d + .25q = 3.05
d=-q + 20
.10(-q + 20) +.25q = 3.05
-.10q + 2 + .25 = 3.05
.15q + 2 = 3.05
.15q + 2 - 2 = 3.05 - 2
.15q = 1.05
.15q/.15 = 1.05/.15
q = 7
d + 7 = 20
d + 7 - 7 = 20 - 7
d = 13
Sally has 7 quarters and 13 dimes.
Hope this helps!
Step-by-step explanation:
1: change 'sin²A' and 'cos²B' into (1-cos²A)and (1-sin²A) respectively.
2:open the brackets and put signs accordingly.
3: cancel (-1) and (+1).
4: remaining is your answer.
Answer:
{-9, -3, 0, 5, 7}
Step-by-step explanation:
The range of a function includes all possible output values.
In this particular case, the output values are the set {0, -3, -9, 5, 7}.
This is the answer. However, arranging the members of this set in ascending order leads to a nicer appearance: {-9, -3, 0, 5, 7}
The range of the given function is {-9, -3, 0, 5, 7}.
