Answer:

2x - 4

Step-by-step explanation:

Expand the brackets.

10x - 2(4x+5) + 6 = 10x - 8x - 10 + 6

Evaluate like terms.

10x - 8x - 10 + 6 = 2x - 4

Klio2033 [76]

Answer:

$(g\circ h)(x)=-x^2-x-3$

Step-by-step explanation:

So we have the two functions:

$g(x)=-x-3\text{ and } h(x)=x^2+x$

And we want to find:

$(g\circ h)(x)$

This is the same thing as:

$=g(h(x))$

So, substitute h(x) into g(x):

$g(x)=-x-3\\g(h(x))=-(x^2+x)-3$

Distribute the negative:

$g(h(x))=-x^2-x-3$

And we're done!

So:

$(g\circ h)(x)=-x^2-x-3$

If you want to convert quarts to cups, should you multiply or divide?

bonufazy [111]

<h3>Answer: Multiply by 4</h3>

This is because 1 quart = 4 cups

So if you had say 3 quarts, then it converts to 3*4 = 12 cups.

The mean can be found by adding the two numbers and dividing by 2

let the second number be y

(x + y)/2 = 1/2x + 1

solve for y

multiply each side by 2
x + y = 2(1/2x + 1)
distribute
x + y = x + 2
subtract x on both sides
y = 2

ANSWER: the second number is 2
