To solve this you have to divide 90 by 10 which would be 9 so

t=9

Hope it helps

Which of the following values are zeros for the function below g(x)=(x2+4x-12)(x-3)

Brilliant_brown [7]

Answer:

Step-by-step explanation:

$g(x)=(x^2+4x-12)(x-3)=(x^2+6x-2x-12)(x-3)\\\\=[x(x+6)-2(x+6)](x-3)=(x+6)(x-2)(x-3)\\\\\text{The zeros for}\ g(x)=0:\\\\(x+6)(x-2)(x-3)=0\iff x+6=0\ \vee\ x-2=0\ \vee\ x-3=0\\\\x=-6\ \vee\ x=2\ \vee\ x=3$

Answer:

4 blue marbles

Skills needed: Number Theory, Fractions

Step-by-step explanation:

1) The problem tells us that the jar contains marbles that are either red, green, or blue (No Other Color).

It also mentions that $\frac{2}{5} (\frac{4}{10})$ of the marbles are red

and that $\frac{1}{10}$ of the marbles are blue

- The given statement is that 20 marbles are green, and we need to find out the number of blue marbles.

2) We need to first find out the total number of marbles, and then multiply that by $\frac{1}{10}$ to get the # of blue marbles.

---> Given $\frac{4}{10}$ are red and $\frac{1}{10}$ are blue, $1-\frac{1}{10}-\frac{4}{10}$ of the marbles are green (since fractions add up to 1 whole)

$1 - \frac{1}{10} - \frac{4}{10} = \frac{9}{10} - \frac{4}{10}=\frac{5}{10}$

$\frac{5}{10} \text{ is also } \frac{1}{2}$

Half the marbles are green.

3) Let's make the total marbles the variable: $m$

$\frac{1}{2} * m=20$ ---> Since half of (of signifies multiplication) the total marbles are green.

Multiply both sides by 2 to isolate: $m = 20*2$ , $m=40$

Total number of marbles is 40.

4) After that, we multiply this by $\frac{1}{10}$ since one-tenth of the total is blue.

---> $\frac{1}{10}*m = \frac{1}{10}*40=4$

4 blue marbles is the answer.

To find (f+g)(x), add the equations and simplify by combining like terms.

(x/2)-2+2x^2+x-3
2x^2+ (x/2) +x -5
2x^2 + (1/2)x+x -5
2x^2+ (3/2)x -5

Final answer: C

Remember that (x/2) is the same as (1/2)x. They both represent half of x.
