Answer:
D) x + y ≤ -4
3x + 2y ≤ -5
Step-by-step explanation:
<u><em>Step(i):-</em></u>
we will choose the system of inequalities
x + y ≤ -4
3x + 2y ≤ -5
x + y = -4 ...(i)
3x + 2y = -5..(ii)
Multiply equation (i) with '3'
3x + 3y = -12
3x + 2 y = -5
<u> - - +</u>
<u> 0 + y = -7 </u>
<u>Step(ii):- </u>
Substitute y = -7 in equation (i)
x + y = -4
x - 7 = -4
x = -4 + 7
x = 3
<em>The solution of the given inequalities is ( 3, -7)</em>

Answer:
The expected number of jobs is given by the function
Step-by-step explanation:
Given that, there were 230,600 jobs available in the field radiology in the year 2014 and the grow at a rate 0.9% each year.
This is a exponential growth.
Exponential grow function:
P(t)= Amount after t years
= The initial amount
r= rate of grow
t = Time in year.
Here P(t)= j(t), = 230,600, r=0.9%=0.009, t=t
The expected number of jobs is given by the function
