I am assuming you want to construct a sentence from 1 and 2:
Zela lived in Zee.
Answer:
f^-1/2(x)=x/1/2-7/2
Step-by-step explanation:
Replace f(x) with y
Y=1/2x+7
Interchange the variable
X=1/2y+7
Solve For y
Rewrite the equation as
1/2y+7=x
Add -7 to both side
1/2y+7-7=x-7
1/2y=x-7
Divide each term with 1/2
1/2y/1/2=x/1/2-7/1/2
Y=x/1/2-7/2
Solve for hand replace with f^-1/2(x)
f^-1/2(x)=x/1/2-7/2
An open circle means not equal to. So, if your equation is x < 4, You would put an OPEN circle at four because it can't equal four.
Answer:
4.
Step-by-step explanation:
First, you have to decide whether the slope is negative or positive. Since the line is going diagonally upward, it is positive.
That means the answer has to be either 3 or 4.
Next, you have to decide whether the y-intercept is negative or positive, on the graph, you can see that it is positive.
Answer choice 4 is the only equation where both the slope and the y-intercept are positive, so it is the answer.
