It is not a function because there have to be at least one value of x that produces multiple values of y. In fact, any x value greater than 0 yields two y values. If x = 0, then y = 0 is the only solution. Negative x values don't produce any real y values.

How do I express y in terms of x?

Dmitrij [34]

Answer:

Solve for ‘y' means, solve the equation to get the value of y.

And in terms of x , means, value of y not necessarily in pure constant form, but in the form of x.

Step-by-step explanation: Here's an example

3y +x = 7

=> y = (7-x)/3

Question is attached

Answer:

x = 12

perimeter = 124

Step-by-step explanation:

The midline RS is half the length of MN, so we have ...

2×RS = MN

2(x +3) = 5x -30

2x +6 = 5x -30

36 = 3x . . . . . . . . . add 30-2x

12 = x . . . . . . . . . . divide by 3

The length RS is then ...

RS = x +3 = 15

and the perimeter of QRS is ...

P(QRS) = QR +RS +SQ = 25 +15 +22 = 62

The perimeter of QRS is half the perimeter of MNP, so ...

P(MNP) = 2×P(QRS) = 2×62 = 124

The perimeter of ΔMNP = 124.

What is the slope of the line through the points (-2, -1) and (4, 3)?

Natalka [10]

Answer:

#2 option: $\frac{2}{3}$

Step-by-step explanation:

$slope=\frac{rise}{run} =\frac{y^2-y^1}{x^2-x^1}$

$\frac{3-(-1)}{4-(-2)}=\frac{-4}{-6} =\frac{-2}{-3} =\frac{2}{3}$

= $\frac{2}{3}$
