Answer:
c = -2
Step-by-step explanation:
4(3+c)+c=c+4 =
4(3+c)+c-c=c+4-c =
4(3+c)=4 =
[4(3+c)]/4=4/4 =
3+c=1 =
3+c-3=1-3 =
c = -2
Answer:
Rate = 0.11%
Step-by-step explanation:
Using I = PRT
Where,
- P = Principal = $1200
- R = Rate = ✘
- T = Time in years = 0.75 years
- I = Interest = $99
⟼ I = PRT
Substitute values
⟼ 99 = 1200 × 0.75 × ✘
Multiply
⟼ 99 = 900✘
Divide both sides by the coefficient of ✘
⟼ 99/900 = ✘
⟼ ✘ = 0.11
Therefore, Rate is 0.11%
Answer:
a = -5
Step-by-step explanation:
15 - a = 20
Move the constant of 15 to the other side by subtracting it.
-a = 5
Divide by -1 to make a positive.
a = -5
Check.
15 - (-5) = 20
15 + 5 = 20
20 = 20
A. The relation is a function if one x-value goes out to one <em />y-value. We can check the graph for that. Does any x-value come out to more than one y-value? No, so, therefore, yes, the relation is a function.
B. The domain is all the x-values shown in the relation. Therefore, it is Domain:{-4, -3, -2, 0, 2, 3}
C. Like the domain question, it is the y-values shown. Therefore, the range is Range: {2, 0, -1, 2, -3, 3}
D. The value of y is at x=2 is the y-value of the point that it shows in the relation when x = 2. We find the point where x=2 (the fifth one from the left), and the y-value there is -3
