Answer:
{12,15}
Step-by-step explanation:
Given the function f(x) = x+5, if the range of the function is {7,9}, the domain of the function is derived by simply finding the value of the function at each end point.
At endpoint x = 7,
f(7) = 7+5
f(7) = 12
At endpoint x = 9
f(9) = 9+5
f(9) = 14.
The function domain is therefore at {12,14}
The sum would end us as: 2.33333333
M = (20 - 12)/(4 - 2)
= 8/2
= 4
slope = m = 4
Answer:
1395 times.
Step-by-step explanation:
The Williams family open their door 28 + 17 = 45 times a day.
So in October they opened it 31 * 45 = 1395 times.
To answer this, we let x some factor that would agree or make the ratio given true. We calculate as follows:
<span>2:3:4
2x:3x:4x
2x = 12
x = 6
Therefore, the length of the longest side would be 4x = 4(6) = 24 cm, third option.</span>
