$\frac{2x}{5} + 1 = \frac{1}{15}$

---------------------------------------------------------
Take away 1 from both sides
---------------------------------------------------------
$\frac{2x}{5} = \frac{1}{15} - 1$

---------------------------------------------------------
Evaluate the value on the right
---------------------------------------------------------
$\frac{2x}{5} = - \frac{14}{15}$

----------------------------------------------------------
Multiply by 15 on both side
---------------------------------------------------------
$\frac{2x}{5} \times 15 = - \frac{14}{15} \times 15$

---------------------------------------------------------
Evaluate
---------------------------------------------------------
$6x = -14$

---------------------------------------------------------
Divide by 6 on both sides
---------------------------------------------------------
$x = - \frac{14}{6}$

---------------------------------------------------------
Simplify
---------------------------------------------------------
$x = - \frac{7}{3}$

$Answer \: x = - \frac{14}{6} \ or - \frac{7}{3}$

goldenfox [79]

Answer:

Option D y=3

Step-by-step explanation:

The question in English is

Which of the following functions is a constant function?

we know that

A constant function is a function whose output value is the same for every input value

Verify each case

case A) y=x+1

This is not a constant function, this is a linear equation

Is a function whose output value is different for every input value

case B) y=x+2

This is not a constant function, this is a linear equation

Is a function whose output value is different for every input value

case C) x=y+3

This is not a constant function, this is a linear equation

Is a function whose output value is different for every input value

case D) y=3

This is a constant function

Is a function whose output value is the same for every input value

The product of 5 and a number is at least 20

Natasha_Volkova [10]

this is the best thing i could find for you, good luck with your question,

5x is greater than or equal to -25

The product of 5 and a number is at least –25

we convert the given statement into inequality

product means multiplication

Let x be the unknown number

product of 5 and a number is 5x

5x is at least -25

For word at most we use <=

for word at least we use >=

So the expression becomes 5x <= -25
