Solve for .x. x-2(3-2x) = 2x +9

Mathematics
1 answer:
Zepler [3.9K]3 years ago
5 0

Answer:

Step-by-step explanation:

X-2(3-2x)=2x+9

First you distribute the -2

So it will then be x-6+4x=2x+9

Combine like terms now so the x’s first

5x-6=2x+9

Now subtract the 2x from the 5x

3x-6=9 now you need to get the 6 to the other side so add it on both sides 3x=15

Divide both sides by 3 and you get x=5

729 = blank to the third power
Crazy boy [7]
One way is to factor and group and get every 3
729=3 times 3 times 3 times 3 times 3 times 3
so we group the ones that happen 3 times
729=(3*3*3) times (3*3*3)
we know that we can take the cube root of each group and multiply the result
729=( \sqrt[3]{3*3*3})( \sqrt[3]{3*3*3})=(3)(3)=9

the answer is 9

the functions f and g are defined as follows f(x)=-5x+2 g(x)=3x^2-3x find f(g) and g(-2) simplify your answer as much as possibl
daser333 [38]

Answer:

f(g) = -15x^2 + 15x + 2.

g(-2) = 18.

Step-by-step explanation:

f(g) = -5(3x^2 - 3x) + 2

= -15x^2 + 15x + 2.

g(-2) = 3(-2)^2 - 3(-2)

= 12 + 6

= 18.

Step-by-step explanation:

if she had 10 left at the end and you add the other half from lunch which is 12, then that gives you 22. Since before lunch she had half (22), all you gotta do is add the other half which is 22. 22+22=44 and that's your answer.
