The standard form of a quadratic equation is expressed as;

ax²+bx+c = 0

Given the quadratic equation x²−7x+10

To factor this expression, we need to get two values if when multiplied will give 10 (product of the coefficient of x²and the constant term) and the sum will give -7(coefficient of x).

The two values are:

-2 and -5

-2 * -5 = +10-2-5 = -7

2 and 5

2 * 5 = 102 + 5 = 7

1 and 10

1 * 10 = 0

-1 and -10

-1 * -10 = 10

If f(3) = 12, which of the following could be a solution for the equation f(x).

Answers

Answer

f(x) = 3x+3

Explanation

So basically your replacing x with 3 to see which one would turn out to be 12.

3(3) = 9

2(3)+12 = 18

3(3)+3 = 12

(3)+10 = 13

Only the third one becomes 12 when you replace x with 3, so the answer is number 3.

The function of which f(3) = 12  is the solution is f(x) = 3x + 3 thus option (C) will be correct.

What is a function?

The function is a relationship between variables, and the nature of the relationship defines the function for example y = six and y = x +6 like that.

Given the solution of an unknown function,

f(3) = 12

If it is the solution then it must satisfy the respective function.

By cross-checking options ;

Option (A) →

f(3) = 3×3 = 9 so it will not the function.

Option (B) →

f(3) = 2(3) + 12 = 18 so it will not the function.

Option (C) →

f(3) = 3(3) + 3 = 12 so it will be the respective function.

Hence "The function of which f(3) = 12  is the solution is f(x) = 3x + 3".

Evaluate the expression
(120 divided by 20)divided by (2x3)

My question is how do I get the answer?

Answers

Answer: 1

Step-by-step explanation:

We are given:

(120/20) / (2 * 3)

Simplify the numerator first:

120/20 = 6

Simplify the denominator:

2 * 3 = 6

Put them together and simplify one final time:

6/6 = 1

The expression (120 divided by 20) divided by (2 times 3) evaluates to 1.

Here, we have,

given

the expression (120 divided by 20)divided by (2x3)

To evaluate the expression:

(120 divided by 20) divided by (2 times 3)

First, we can simplify within the parentheses:

120 divided by 20 = 6

2 times 3 = 6

Now we have:

6 divided by 6

Since both the numerator and denominator are the same, the result is 1:

6 divided by 6 = 1

Therefore, the expression (120 divided by 20) divided by (2 times 3) evaluates to 1.
