Let the function be f defined by f (x) = 12 - 5x
marissa [1.9K]

(a) No

f(x) = 12 - 5x

f(0) = 12 - 5(0)

f(x) = 12 - 0

f(x) = 12

Hence,

f(0) is unequal to 0.

(b)

f(x) = 12 - 5x

f( - 1) = 12 - 5( - 1)

f( - 1) = 12 + 5

f( - 1) = 17

(c)

f(x) = 12 - 5x

f(x) = 6

6 = 12 - 5x

6 - 12 =  - 5x

- 6 =  - 5x

6 = 5x

\frac{6}{5}  = x

5x+6y=18and 18x-15y=36<br> parallel or perpendicular
Katen [24]

Answer:

<u>They</u><u> </u><u>are</u><u> </u><u>neither</u><u> </u><u>parallel</u><u> </u><u>nor</u><u> </u><u>perpendicular</u><u>,</u><u> </u><u>since</u><u> </u><u>slope</u><u> </u><u>are</u><u> </u><u>different</u><u> </u><u>and</u><u> </u><u>not</u><u> </u><u>related</u><u> </u><u>by</u><u> </u><u>any</u><u> </u><u>equation</u>

Step-by-step explanation:

First arrange them according to general equation:

y = mx + c

<u>f</u><u>o</u><u>r</u><u> </u><u>t</u><u>h</u><u>e</u><u> </u><u>f</u><u>i</u><u>r</u><u>s</u><u>t</u><u> </u><u>e</u><u>q</u><u>u</u><u>a</u><u>t</u><u>i</u><u>o</u><u>n</u> :

5x + 6y = 18 \\ 6y =  - 5x + 18 \\ { \boxed{y =  -  \frac{5}{6} x + 3}}

<u>f</u><u>o</u><u>r</u><u> </u><u>t</u><u>h</u><u>e</u><u> </u><u>s</u><u>e</u><u>c</u><u>o</u><u>n</u><u>d</u><u> </u><u>e</u><u>q</u><u>u</u><u>a</u><u>t</u><u>i</u><u>o</u><u>n</u> :

18x - 15y = 36 \\ 15y = 18x - 36 \\ y =  \frac{18}{15} x -   \frac{12}{5}

N is the set of odd natural numbers greater than 11 and less than 21. Use set notation to write the elements of N. N
S_A_V [24]

Answer:

N = {13, 15, 17, 19}

Step-by-step explanation:

The natural numbers greater than 11 and less than 21 are:

12, 13, 14, 15, 16, 17, 18, 19 and 20

Odd numbers are numbers that have remainders when divided by 2. Out of the numbers above, the numbers with remainders when divided by 2 are 13, 15, 17 and 19.

Since N is the set of odd natural numbers greater than 11 and less than 21,

N = {13, 15, 17, 19}
