Answer:

The correct answer would be 4. Explanation below

Step-by-step explanation:

-6x-11x = 68

-6x-11x = -17x

-17x = 68

Answer:

Hey there! The correct answer would be x=-4.

Step-by-step explanation:

To start, you would first need to combine your like terms, terms that are not only raised to the same power but also have the same exact variables. In this case, your like terms are -6x and -11x:

-6x-11x=68 --> -17x=68

Now, divide both sides by -17 in order to isolate your variable term:

-17x/-17 = 68/-17

x=-4

Therefore, your answer would be x=-4.

To check to make sure this answer is right, plug -4 in for x and see if the result is 68=68:

-6(-4)-11(-4)=68

24+44=68

68=68


Hope this helps! :)

Arun scores 36 marks in English 44 marks in Hindi and 75 marks in maths and X in Science if average score is 50 find the value o
Gnoma [55]

Answer:

x = 45

Step-by-step explanation:

The average is calculated as

average = \frac{score}{count}

here the average = 50 , thus

\frac{36+44+75+x}{4} = 50

Multiply both sides by 4

36 + 44 + 75 + x = 200

155 + x = 200 ( subtract 155 from both sides )

x = 45

AUTOMOBILES The engine torque y (in foot-pounds) of one model of car is given by y = º3.75x2 + 23.2x + 38.8 where x is the speed
Scilla [17]

Answer:

Part 1) The engine speed that maximizes torque is 3,093 rev/min

Part 2)The maximum torque is 74.683\ foot-pounds

Step-by-step explanation:

<u><em>The correct equation is</em></u>

y=-3.75x^{2}+23.2x+38.8

This is the equation of a vertical parabola open downward (because the leading coefficient is negative)

The vertex represent a maximum

The x-coordinate of the vertex represent the engine speed that maximizes torque

The y-coordinate of the vertex represent the maximum torque

Solve the quadratic equation by graphing

using a graphing tool

The vertex is the point (3.093,74.683)

see the attached figure

therefore

The engine speed that maximizes torque is

3.093(1,000)=3,093 rev/min ---> because is in thousands of revolutions per minute

The maximum torque is

74.683\ foot-pounds
