Is 6x-8 equal to 2(3x-5)? Also, btw the x is a variable... not the multiplication sign.

No, it is not. Using the distributive property, multiply 2 to 3x and -5 to get 6x-10. 6x-8 does not equal 6x-10, they have the same coefficient by not the same constant.

No because 2(3x-5) is equal to 6x-10 not 6x-8

F(x)=-2x+10 what value of x will f(x)=0

trapecia [35]

For x=5 the function will be zero

Further explanation:

In order to find the value on which a particular function will be zero, the function is put equal to zero and the equation is solved for x.

Given function is:

$f(x)=-2x+10\\$

Putting the function equal to zero

$-2x+10=0\\Subtracting\ 10\ from\ both\ sides\\-2x+10-10=0-10\\-2x=-10\\Dividing both sides by -2\\\frac{-2x}{-2}=\frac{-10}{-2}\\x=5$

For x=5 the function will be zero i.e.

f(x)=0

We can verify:

$f(5) = -2(5)+10\\=-10+10\\=0$
