Which of the following are solutions to | x-1|= 5x + 2 ? Check all that apply.

agasfer [191]

By definition of absolute value, if $x-1\ge0$ , then $|x-1|=x-1$ , so

$|x-1|=5x+2\implies x-1=5x+2\implies4x=-3\implies x=-\dfrac34$

On the other hand, if $x-1$ , then $|x-1|=-(x-1)=1-x$ , and

$|x-1|=5x+2\implies1-x=5x+2\implies6x=-1\implies x=-\dfrac16$

If f(x)=-2x-3 find f(4)

Naddik [55]

Answer:

f(4) = -11

Step-by-step explanation:

Plug in 4 for x: Note that x = 4.

f(x) = -2x - 3

f(4) = -2(4) - 3

Remember to follow PEMDAS. First, solve the multiplication, then subtract:

f(4) = (-2 * 4) - 3

f(4) = (-8) - 3

f(4) = -11

f(4) = -11 is your answer.

What is the area of a rectangle of 5/9 m in length and 7/8 m in width

Andru [333]

Answer:

35/72 $m^2$

Step-by-step explanation:

Rectangle Formula: $l*w=Area$

Switch the variables with the numbers given:

$\frac{5}{9} *\frac{7}{8} =Area$

Multiply the top and bottom:

5*7 = 35

9*8 = 72

35/72 = Area

If b is inversely proportional to c, and b is 5 when c is 12, find b when c = 20.

frozen [14]

Answer:

b=3

Step-by-step explanation:

If b is inversely proportional to c then

$b=\frac{k}{c}$

b is 5 when c is 12, means...

$5=\frac{k}{12}$

From where we obtain the value of k, the constant needed, which is equals to 5*12=60

Now... to find b when c=20, is just a matter of using our known variables.

$b=\frac{60}{20}=3$
