Answer:

domain is set of all real number except 4/5

Step-by-step explanation:

$f(x)= (x-3)/(x)$

$g(x)=5x-4$

Now we find (fºg)(x)

(fºg)(x)=f(g(x))

We plug in g(x) inside in f(x)

$f(g(x))=f(5x-4)= ((5x-4)-3)/(5x-4)$

Now simplify the numerator

$f(g(x))=((5x-4)-3)/(5x-4)=(5x-7)/(5x-4)$

To find out domain we set the denominator =0 and solve for x

$5x-4=0$

Add 4 on both sides

$5x=4$

Divide both sides by 5

$x=(4)/(5)$

So domain is set of all real number except 4/5

Plz answer this question is really easy.

Answer:13.5

Really easy just do 4.5 times 3

well to solve this you will need the formula of a triangle: 1/2 (bh)

b= 3cm
h=4.5cm
so you would multiply those: 13.5cm but we’re not done because the formula says that it’s only half of bh

13.5 divided by 2 is 6.75cm

and with area it’s always square so the answer would be 6.75cm2 (i don’t know how to get the 2 small)

Can anyone please help me with 1,2,&,3 ?

Answers

Okay, lets start with number 1.

$(x+3)^(3)$ is also equal to (x+3)(x+3)(x+3)

If you take the first two ones and multiple them out it ends up with $x^(2) + 3x +3x + 9$ or also know as $x^(2) + 6x + 9$

You see to multiply them you take the first number in the first group of parenthesis and use the distributive property on the second equation, then you do the same this but with the second number in the first equation.

So once you have $(x^(2) + 6x + 9)$ you multiply it with your remaining (x + 3) using the distributive property to get $x^3 + 9x^2 + 27x + 27$

I hope this helps you get the answers for the other two.

(x+3)^3 = x^3+9x^2+27x+27

(x+2)(x-2)(x^2+4) = x^4-16

(x-2)^2+1 = x^2-4x+5

Multiply. 560.9 • 2.8
A.15705.2
B.1570.52
C.157.052
D.15.7052

Answers

560.9
* 2.8
ignore the decimals and multiply, as whole numbers.
5609 * 28 = 157052
now since there were two spots behind the decimal, squeeze the decimal in the number.
1,570.52 is the answer. which is B

560.9 x 2.8 = 1570.52

may runs 10/4 miles everyday after school. Beth says that she runs farther than May every day because she runs 5/2 miles everyday after school. is her statement correct

Answers

yes her statement is correct i think well maybe it is because if you cut 3 rectangles in to 2 than you color in 5 and stop and draw a rectangle with 4 in 3 rectangles and color in 10 and the two has less shaded in so the one who ran more was beth cause if you put it into a mixed number it is 2 and 1/2 and May's mixed number is 2 and 2/4 and the dinominator 2 is greater than the dinominator 4 cause 2 has bigger pices and 4 has smaller pices
