When the variable is attached like 2a you divide to isolate. When it is 2+a you subtract 2 to the other side and when it’s -2+a you add to the other side!

I'm going to try this one more time...
irina [24]

Answer and Step-by-step explanation:

<u>C and D  is the answer.</u>

It needs a lot of mass so that it can collapse on itself to form a black hole, and when it dies, it also collapses on itself, forming a black hole.

A is incorrect because the mass of our sun hasn't made it to collapse, and it still has some billions of years before the mass increases.

B is incorrect because the hydrogen needs to be depleted in order for the sun/star to start the nuclear process.

NEED HELP ASAP<br><br> Question A.) k=5<br> Question B.) ????
andrezito [222]

Answer:

b) f^{-1}(x) = \frac{4x+5}{3}

Step-by-step explanation:

b) To find the inverse function, switch the x and y variables and solve for y:

f(x) = \frac{3x-5}{4}\\y = \frac{3x-5}{4}\\x = \frac{3y-5}{4}\\4x = 3y-5\\4x+5 = 3y\\\frac{4x+5}{3} = y\\f^{-1}(x) = \frac{4x+5}{3}

Verify Answer:

f(1) = \frac{3(1)-5}{4} = -0.5\\f^{-1}(-0.5) = \frac{4(-0.5)+5}{3} = 1
