The inequality that describes the possible values of the expression is:
<h3>What is the lower bound of values of the expression?</h3>
The expression is given by:
To find the lower bound, we try to see when the expression is negative, hence:
Applying cross multiplication and simplifying the 3's, we have that:
From the bounds given, this expression will never be true, at most they can be equal, when:
a = b = 4.
Hence the lower bound of values of the expression is of 0.
<h3>What is the upper bound of values of the expression?</h3>
The expression is a subtraction, hence we want to maximize the first term and minimize the second.
Considering that the first term is direct proportional to b and inverse to a, and the second vice versa, we want to:
Then:
Hence the bounds are:

Answer:
y=0.012x+0.65
Step-by-step explanation:
And again y=mx+c
we have 4 point given in the question
(50,1.25) ( 100,1.85) ( 150,2.45) (200,3.05)
we can find the M ( gradient/Slope) by using 2 of them with the formula
I am using the first 2 (50,1.25) ( 100,1.85)
which in decimal form is 0.012
with that cross out the first option as its wrong
now to find c, like in the previous two question, put the m, x and y in the equation and solve for C
I am gonna use the 3rd coordinates for this one (150,2.45)
2.45=0.012(150)+c
2.45=1.8+c
0=1.8-2.45+c
-c=-0.65
c=0.65
So our completed equation is y=0.012x+0.65
The third answer is correct :)
It’a the third , and can I have the brainliest too
b becuces you add the dived
For this case, the first thing we must do is define variables.
We have then:
x: governor of a state gains
y: governor of b state earnings
We now write the system of equations that models the problem.
We have then:
Solving the system of equations we have:
Then, for x:
Answer: governor of a state earns $ 170395
governor of b state earns $ 115770
