Decide whether the relation is a function or not.<br> {(-3, 5), (-2, 5), (0, 5), (1, 5), (2, 5)}
DerKrebs [107]

Answer:

[see below]

Step-by-step explanation:

A functions input is assigned to exactly one output. This means that the inputs must not repeat.

{(-3, 5), (-2, 5), (0, 5), (1, 5), (2, 5)}

Since no inputs repeat, the relation given is a function.

Hope this helps.

Which Exponential equation is equivalent to the logarithmic equation below? <br> C= in 3
Bess [88]

Answer

e^c = 3

Step by step explanation

The general exponential equation is y = a^x, where "a" is the base and "x" is the exponent.

We are given c = ln 3

Here the base is "e"

e^c = e^ln 3

e^c = 3             [base "e" and "ln" get cancelled because they are inverse]

Therefore, the answer is e^c = 3

Hope you will understand the concept.

Thank you.

Write an equation of the line that passes through (7,10) and is perpendicular to the line y=12x−9.
Ulleksa [173]

Answer:

<em>y = - </em>\frac{1}{12}<em> x + </em>\frac{127}{12}<em> </em>

Step-by-step explanation:

y = 12x - 9

Slope of line perpendicular to given is m = - \frac{1}{12}

P(7, 10)

y - 10 = - \frac{1}{12} (x - 7)

<em>y = - </em>\frac{1}{12}<em> x + </em>\frac{127}{12}<em> </em>
