Seriously someone help me i answered it but i don’t know if it is right so please tell me if it is and how i got the answer or p

Answer:

<h2>C</h2>

Step-by-step explanation:

To determine a function rule, look at the table. Input the x and y value from one column into the function to see if it is correct.

<h3>Function a: y = 10 - 2x</h3>

Input values

22 = 10 - 2(6)

22 = 10 - 12

22 ≠ -2 ❌

As we can see, function a gives us a false statement, so a is incorrect.

<h3>Function b: y = 2 - 10x</h3>

Input values

22 = 2 - 10(6)

22 = 2 - 60

22 ≠ -58 ❌

We once again get a false answer, so b is also not correct.

<h3>Function c: y = 10 + 2x</h3>

Input values

22 = 10 + 2(6)

22 = 22 ✔

Finally, we get a true statement, so option c is correct.

<h3>Function d: y = 2 + 10x</h3>

Just to check that option c is correct, we need to prove that d is incorrect.

Input values

22 = 2 + 60

22 ≠ 62 ❌

This is also wrong, so that proves that c is correct.

I'm always happy to help :)

It is known that x1 and x2 are roots of the equation 3x^2+2x+k=0, where 2x1=−3x2. Find k.
miss Akunina [59]

Answer:

k = 8

Step-by-step explanation:

Since the roots of the equation 3x² + 2x + k are x₁ and x₂ and 2x₁ = 3x₂.

By the roots of an equation, ax² + bx + c , where its roots are  x₁ and x₂. It follows that sum of roots are x₁ + x₂ = -b/a and product of roots are x₁x₂ = c/a.

Comparing both equations, a = 3 b = 2 and c = k.

So, x₁ + x₂ = -b/a = -2/3 and x₁x₂ = c/a = k/3

x₁ + x₂ = -2/3 and x₁x₂ = k/3

3x₁ + 3x₂ = -2 (1) and 3x₁x₂ = k  (2)

Since 2x₁ = -3x₂, and -2x₁ = 3x₂substituting this into equations (1) and (2) above, we have

3x₁ + 3x₂ = -2 (1) and 3x₁x₂ = k  (2)

3x₁ + (-2x₁) = -2  and x₁(3x₂) = k

3x₁ - 2x₁ = -2  and x₁(3x₂) = k  

x₁ = -2  and x₁(-2x₁) = k  

x₁ = -2  and -2x₁² = k  

Substituting x₁ = -2 into -2x₁² = k, we have

-2x₁² = k

-2(-2)² = k

2(4) = k

8 = k

So, k = 8
