Answer:
30 min
Step-by-step explanation:
1 / ( 1/20 + 1/ x) = 12
1 = 12/20 + 12/x
8/20 = 12/x
x = 12 * 20 / 8 = 30 min
Answer:
- <u>Domain</u> : -1 ≤ x ≤ 3
- <u>Range</u> : 6 ≤ y ≤ 27
Step-by-step explanation:
The domain is the set of possible x-values.
The range is the set of possible y-values.
<u>Domain</u> : -1 ≤ x ≤ 3
<u>Range</u> : 6 ≤ y ≤ 27
Answer:
Step-by-step explanation:
3x + 6 = 8 + 3x - 2
3x + 6 = 3x + 6
Bringing like terms on one side
3x - 3x = 6 - 6
0 = 0
6(3 + 5) =
6 x 8 =
48
Your answer shall be A.
If you want to turn this into an equation, use the equation y = mx + b
m = slope or rate of change
b = y-intercept, or your starting value
y = 35x + 55
