For the answer to the question above, the answer is C. 4(x + 3). The expression means that the sum of x and 3 is multiplied by 4. This expression should be equal or greater than 28. I hope my answer helped you. Feel free to ask more questions. Have a nice day!

Lets check the first point (0,6)


3*0+4=4  no good

0+6 =6  good

0^2+6 =6 good

6 * (7/6) ^0 =6  good


Lets check the second point (1,7)

3*1+4=  we don't care since it didn't work for (0,6)

1+6 =7

1^2+6 =7

6 * (7/6) ^1 =7


Lets check the third point (2,10)


3x+4=  we still don't care

2+6 = 8 no good

2^2+6 =10  good

6 * (7/6) ^2 =6 * 49/36 =49/6  no good


f(x) = x^2 +6

Find the points which defined the reflection of the figure giving by A(2,2) B (3,7) C (5,5) reflected across the X-axis
elixir [45]

well the formula to reflecting across the x-axis is (x,-y).so the final points are A'(2,-2)   B'(3,-7)  C(5,-5) ANSWER



additional information

By the way the -y in the formula does not mean every number will always be negative it means switch the sign  so if the point is (5,-7) than reflecting across the x-axis it would be (5,7)

Determine which elements of S satisfy the inequality
kumpel [21]

Answer:

The elements of S-block elements are 14, so therefore to create an inequality model we declare S to be the unknown variable.

therefore since we have 14 elements we use an inclusive class interval from 1-14. the model is given as

1≤S≥14

Step-by-step explanation:

you have to declare variables before for the unknowns.

you also declare the class interval to be inclusive class interval or exclusive class interval.
