How can you identify a linear nonproportional relationship from a table, a graph, and an equation?

On-proportional linear relationships can be expressed in the form y = mx + b, where b is not 0, m represents the constant rate of change or slope of the line, and b represents the y-intercept. The graph of a non-proportional linear relationship is a straight line that does not pass through the origin.

if h(x)=5+c and k(h)=1/x, which expression is equivalent to (k•h)(x) a. (5+x)/x b.1/(5+x) c. 5+(1/x) d. 5+(5+x)

Maru [420]

Answer:

A

Step-by-step explanation:

So we have the two functions:

$h(x)=5+x \text{ and } k(x)=1/x$

And we want to find:

$(k\cdot h)(x)$

This is the same as saying:

$(k\cdot h)(x)\\=k(x)\cdot h(x)$

Thus, substitute them for the equations:

$=k(x)\cdot h(x)\\=(\frac{1}{x})\cdot(5+x)$

Multiply:

$=\frac{5+x}{x}$

Therefore:

$(k\cdot h)(x)=\frac{5+x}{x}$

The answer is A.

Perform the indicated operation. (-3 + 5i) - (7 + 9i)

Gala2k [10]

Answer:

-10 -4i

Step-by-step explanation:

To subtract complex numbers, subtract the real parts.

-3 -7 = -10

and then the complex parts.

5i-9i = -4i

(-3 + 5i) - (7 + 9i) = -10 -4i
