Answer: -6 = x

Step-by-step explanation: Start by distributing through the parentheses

on each side of the equation to get 5x - 40 = 7x - 28.

Now move your x's to the right and

numbers to the right and you get -12 = 2x.

Divide both sides by 2 and -6 = x

Answer:

Hi You

5(x -8) = 7(x -4)

5x - 40 = 7x - 28

5x - 40 + 40 = 7x - 28 + 40

5x = 7x + 12

5x -7x = 7x - 7x +12

-2x = 12

-2x/-2 = 12/-2

x = -6

Step-by-step explanation:

proving my answer.

5(-6 - 8)

(5×-6)-(5×8)

= -30-40

= -70

7(-6-4)

(7×-6) - (7×4)

-42 - 28

= -70

hope that will help you.

Cos^-1(-x)=-Cos^-1x for -1<x<1 TRUE OR FALSE?

VMariaS [17]

We are given

$cos^{-1}(-x)=-cos^{-1}(x)$

Firstly, we will simplify left side

and we will check whether it is equal to right side

Left side:

Let's assume y left side expression

$y=cos^{-1}(-x)$

now, we can take cos on both sides

$cos(y)=cos(cos^{-1}(-x))$

we can simplify it

$cos(y)=-x$

Right side:

Let's assume y left side expression

$y=-cos^{-1}(x)$

Multiply both sides by -1

$-y=cos^{-1}(x)$

now, we can take cos on both sides

$cos(-y)=cos(cos^{-1}(x))$

we can simplify it

$cos(-y)=x$

$cos(y)=x$

we can see that

both sides cos(y) value is different

so, this is FALSE.........Answer
