Annabelle's homework is 75% it took her three hours how long should she estimate it will take her to complete her homework.

1 answer:

8 0

It will take Annabelle 4 hours to complete her homework. If it took her 3 hours to finish 75%, then it probably took her 1 hour for every 25% she finished. If she finished 75%, she has 25% left to be done or 100% complete. 25% = 1 hour. So 3 hours + 1 hour = 4 hours or 100% complete

If f(x)=x+3 and g(x)=x-3 find (f-g)(x)

maw [93]

Answer:

$(f-g)(x)$ $=6$

Step-by-step explanation:

Given:

$f(x)=x+3\\g(x)=x-3$

To find $(f-g)(x)$

Solution:

In order to find $(f-g)(x)$ we will subtract the function $g(x)$ from $f(x)$

So, we have:

$(f-g)(x)$ $=f(x)-g(x)$

Plugging in $f(x)$ and $g(x)$ in the above combinations of functions.

$(f-g)(x)$ $=(x+3)-(x-3)$

Simplifying by removing the parenthesis and reversing the signs of the terms in the parenthesis after the negative.

$(f-g)(x)$ $=x+3-x+3$

Combining like terms.

$(f-g)(x)$ $=x-x+3+3$

∴ $(f-g)(x)$ $=6$

Help, answer one that hasn’t been answered

4x + 2x = < y

This is because the opposite sides (which is 4x and 2x) of a triangle add up to the exterior angle (<y).

We have to find X.

As you know:

$3x + 4x + 2x = 180$

because the angles of a triangle add up to 180.

When we add them:

$9x = 180$

$x = \frac{180}{9}$

The 9 is multiplying with the X. We want X only and not 9 with it. So, when we take 9 to the other side, it becomes divide. As a result, the answer to x is:-

$x = 20$
