Hey there!

Here goes your answer ↓

Question:- State whether the given equation or function is linear. Write yes or no. Explain your reasoning. f(x) = 7x² + 4

(a) Yes, the equation is linear. It is of the form f(x) = m + b

(b) Yes, the equation is linear form. It is of the form f(x) = mx + b.

(c) No, the equation is not linear. It is in the form x + y = c.

(d) No, the equation is not linear. It is not of the form f(x) = mx + b.

<em>Answer</em> :- <em>Option</em><em> </em><em>(</em><em>D</em><em>)</em><em> </em>

<em>Explana</em><em>tion</em><em> </em><em>:</em><em>-</em><em> </em>

<em> </em><em>Given</em><em> </em><em>equ</em><em>ation</em><em> </em><em>:</em><em>-</em><em> </em><em>f(x) = 7x</em><em>²</em><em> + 4 </em>

<em>•</em><em>T</em><em>h</em><em>e</em><em> </em><em>form</em><em> </em><em>of</em><em> </em><em>any</em><em> </em><em>equation </em><em>should</em><em> </em><em>be</em><em> </em><em>→</em><em> </em><em>y</em><em> </em><em>-</em><em> </em><em>mx</em><em> </em><em>+</em><em> </em><em>b</em>

For this case we have the following function:

f (x) = 7x ^ 2 + 4

By definition, we have that a linear equation is of the form y = mx + b

On the other hand, a quadratic equation is of the formy = ax ^ 2 + bx + c

Then, the given equation is not a linear equation, it is not of the form y = mx + b

Answer:

No, the equation is not linear. It is not of the form f (x) = mx + b.

Two non-perpendicular, non-bisecting, intersecting line segments definition
hichkok12 [17]
Line segments are parts of line that have fixed ends. For them to be perpendicular, the angle between them should be 90°. Bisecting lines are those that cut each other into two equal parts. If the lines intersect but the conditions above are not satisfied then, the lines are non-perpendicular and non-bisecting, intersecting lines.

A alone can complete a work in 16 days and B alone can complete the work in 12 days. How many days will it take to complete the
Agata [3.3K]

Answer:

14 days

Step-by-step explanation:

1. Convert the amount of work person A and B can do respectively in one day into fractions.

                                        A = 1/16                  B = 1/12

2. Get both fractions to a common denominator using the least common multiple. This is 48.

                                1/16 × 3 = 3/48        1/12 × 4 = 4/48

3. Add both fractions to find out how much work will be done in two days.  We are doing this because we are working in a pattern, and this will allow us to multiply, which is more time efficient than repeatedly adding 3 and then 4.

                                               3/48 + 4/48 = 7/48

4. Figure out how many sets of two days work (7/48) will get them to 48/48 (100% done) or closest to it without being under. This would be 7 sets.

                                               7/48 × 7 = 49/48

5. Multiply 7 by 2. We are doing this because we worked in sets of two days to account for A working and then B, since they are taking turns.

                                                    7 × 2 = 14

6. It will take them 14 days.
