What times what will give you 15? It's elementary my dear.
3•5=15
1•15=15
The factors are: 1, 3, 5, 15.

$x=0.\overline{3}\\
10x=3.\overline{3}\\
10x-x=3.\overline{3}-0.\overline{3}\\
9x=3\\
x=\dfrac{3}{9}=\dfrac{1}{3}\\\\
x=-0.\overline{2}\\
10x=-2.\overline{2}\\
10x-x=-2.\overline{2}-(-0.\overline{2})\\
9x=-2.\overline{2}+0.\overline{2}\\
9x=-2\\
x=-\dfrac{2}{9}\\\\
x=1.\overline{7}\\
10x=17.\overline{7}\\
10x-x=17.\overline{7}-1.\overline{7}\\
9x=16\\
x=\dfrac{16}{9}=1\dfrac{7}{9}$

$x=-2.\overline{6}\\
10x=-26.\overline{6}\\
10x-x=-26.\overline{6}-(-2.\overline{6})\\
9x=-26.\overline{6}+2.\overline{6}\\
9x=-24\\
x=-\dfrac{24}{9}=-2\dfrac{2}{3}\\\\
x=0.4\overline{6}\\
10x=4.\overline{6}\\
100x=46.\overline{6}\\
100x-10x=46.\overline{6}-4.\overline{6}\\
90x=42\\
x=\dfrac{42}{90}=\dfrac{7}{15}$

$x=-1.8\overline{3}\\
10x=-18.\overline{3}\\
100x=-183.\overline{3}\\
100x-10x=-183.\overline{3}-(-18.\overline{3})\\
90x=-183.\overline{3}+18.\overline{3}\\
90x=-165\\
x=-\dfrac{165}{90}=-1\dfrac{5}{6}$

NO LINKS OR ASSESSMENT!!!<br><br>Part 1: Domain and Range of Graphs<br>

lora16 [44]

Domain is the set of input values
Range is the set of output value
Function is passes the vertical line test

<u>Domain:</u>

- 5 < x < 5 or x ∈ (-5, 5)

<u>Range:</u>

-5 < y < 5 or y ∈ (-5, 5)

<u>Function:</u>

YES - passes the vertical line test

<u>Domain:</u>

- 5 < x ≤ 5 or x∈ (-5, 5]

<u>Range:</u>

-3 < y ≤ 2 or y ∈ (-3, 2]

<u>Function:</u>

YES - passes the vertical line test

<u>Domain:</u>

- 5 < x < 3 or x∈ (-5, 3)

<u>Range:</u>

0 < y < 4 or y ∈ (0, 4)

<u>Function:</u>

N0- doesn't pass the vertical line test

Evaluate this expression: 12 x (3 + 2^2)/2 - 10

BlackZzzverrR [31]

On evaluating the solution is 32

Step-by-step explanation:

Step 1: Use the PEMDAS principle to solve the expression.

⇒ 12 (3 + 2²)/2 - 10 = 12 (3 + 4)/2 - 10

= 12 × 7/2 - 10

= 84/2 - 10

= 42 - 10 = 32
