Answer:

$\{f(x)\ |\ -\infty$

Step-by-step explanation:

The range of the function are all possible values of f(x).

From the diagram you can see that

for all $x\le 0,$ the value of f(x) is always 4;
for $x\ge 0,$ the value of f(x) decreases from 4.

This means that the range of the function f(x) is

$\{f(x)\ |\ -\infty$

If 81 is added to a number the result is 39 less than three times the number

Deffense [45]

let x =the number

Step-by-step explanation:

81+x=3x-39

group like terms

81+39=3x-x

120=2x

120/2=2x/2

60=x

therefore x =60

How would i anser this select all the ratios equivalent to 4:6

Natali5045456 [20]

If we try to simplify the ratio or try to multiply both by any number, we will get the equivalent ratio

Like :

$\frac{4}{6} \\$

Divide ( simplify ) by 2

$\frac{ \frac{4}{2} }{ \frac{6}{2} } \\ \\ \\ = > \frac{2}{3}$

Or multiply by any number,

$\frac{4}{6} \\ \\ \\ = > \frac{4 \times 2}{6 \times 2} \\ \\ \\ = > \frac{8}{12}$

From the example, 2 / 3 and 8 / 12 are equivalent ratios to 4 / 6
