Answer:

x = 4

Step-by-step explanation:

2x + 4 = 6(1/2×)

2x + 4 = 3x

-2x on oth sides

4=×

x is 4

Answer:

A

Step-by-step explanation:

f(x) = (x + 3)(x + 2)(x - 3)

The three roots are going to give - 18 so only A and D can be correct. Why minus? because at some point 3 and 2 and - 3 will all be multiplied together. When they are, the result is - 18

So why did I write x + 2 rather than x - 2? Because the roots turn an equation into 0. You are looking for a way to make x + 2 = 0. It will do that when x = - 2

which is what you were given.

Now to get the answer

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

(x^2 - 9)(x + 2) = x^3 + 2x^2 - 9x - 18 = f(x)

Answer:

Step-by-step explanation:

difference of 10 and u = 10 - u

seven times the sum of twice a number m and 16 is 9 -

7 ( 2m + 16 ) = 9

5x + 6x -  sum of 5 times a number and 6 times a number

8 ( x - 7 ) = -35 - 8 times the difference of a number x and 7 is -35

Answer:

Step-by-step explanation:

We are given the sequence

[tex]15, 29, 49, 75, 107\\15->29 = 14\\29 -> 49 = 20\\49->75 = 26\\75 -> 107 = 32\\14, 20, 26, 32\\14 -> 20= 6\\20 -> 26 = 6\\26 -> 32 = 6\\\\6, 6, 6\\6->6 = 0[/tex]

Since we had to find the differences twice, it is a second degree polynomial

[tex]y = an^2 + bn + c\\plugging \: in \: n = 1, 2, 3...\\the \: sequence \: is \\a+b+c, 4a + 2b + c, 9a + 3b + c...\\the \: diff \: under \: is \\3a + b, 5a + b, 7a + b...\\the \: diff \: under \: is \\2a, 2a, 2a...\\so, \\2a = 6\\a = 3\\3(3) + b = 14\\b = 5\\\\a +b + c = 15\\3 + 5 + c = 15\\c = 7\\[/tex]

so,

[tex]y = 3n^2 + 5n + 7[/tex]

Answer:

(2, 7)

Step-by-step explanation:

hope this helps :)

( 1 ) Find by using a formula of (-b/2a, (4ac-b²)/4a)

[tex](\frac{-b}{2a},\frac{4ac-b^2}{4a})\\(\frac{-12}{2(-3)}),(\frac{4(-3)(-5)-(12)^2}{4(-3)})\\(\frac{-12}{-6}),(\frac{60-144}{-12})\\(2,\frac{-84}{-12})\\(2,7)[/tex]

The vertex is at (2,7)

( 2 ) Find by using a derivative (Calculus)

You can also find a vertex by using a calculus. Using a derivative

[tex]y'=-3x^2+12x-5\\y'=-6x+12\\\\[/tex]

Then substitute y' = 0 to get a vertex.

[tex]y'=-6x+12\\0=-6x+12\\-12=-6x\\2=x[/tex]

Then substitute x = 2 in the equation of y = -3x²+12x-5

[tex]y=-3x^2+12x-5\\y=-3(2)^2+12(2)-5\\y=-3(4)+24-5\\y=-12+24-5\\y=-17+24\\y=7[/tex]

x = 2 and y = 7, therefore. The vertex is (2,7)
