f(x) = -4x2 + 4x - 4
Find f(3)

Answers

Answer 1

Answer:

-28

Step-by-step explanation:

Answer 2

The solution is the value of f(3) = -28.

What is an expression?

An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

here, we have,

given expression is,

f(x) = -4x^2 + 4x - 4

now, we have to find the value of f(3).

so, we have to put x = 3, in the expression.

we get,

f(x) = -4x^2 + 4x - 4

f(3) = -4* 9 + 4*3 -4

or, f(3) = -36 + 12 -4

or, f(3) = -28

Hence, The solution is the value of f(3) = -28.

what is the value of X with f (x) =4

Answers

Answer:

I can find all the x-values in the domain of the function f(x)=4:

Domain = (−∞, ∞), {x | x∈R}

Here’s the range if you need it:

Range: {4}

Hope this helps! :)

The answer is Range: {4} or,  x is a member of the real numbers and that it can be anything from negative infinity to positive infinity.

What is number?

A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words.

Here, we have,

f (x) =4

now,

we can find all the x-values in the domain of the function f(x)=4:

Domain = (−∞, ∞), {x | x∈R}

Here’s the range if you need it:

Range: {4}

There are x’s in the equation.

It’s actually all numbers are x’s because anything you put into the function f(x)=4, y will always equal 4.

So the value of x in f(x)=4 is all numbers.

To be more specific, all real numbers.

That’s why I put (−∞, ∞), {x | x∈R} because x is a member of the real numbers and that it can be anything from negative infinity to positive infinity.

Answers

Answer: -3

Step-by-step explanation: just multiply

The best estimate of the average rate of change for the function graphed over the interval 1 ≤ x ≤ 3 is 3.

What is Average Rate of Change of a Function?

Average rate of change of a function is defined as the rate at which the value of the function is changing with respect to the change in the input values.

The interval given is 1 ≤ x ≤ 3.

The graph of the function is given below.

It can be clearly seen that,

The y value corresponding to x = 1 is y = f(1) = 2.

So one point on the graph is (1, 2).

The y value corresponding to x = 3 is y = f(3) = 8.

So the other point on the graph is (3, 8).

Average rate of change over 1 ≤ x ≤ 3 = [f(3) - f(1)] / [3 - 1]

                                                               = [8 - 2] / [2]

                                                               = 6/2

                                                               = 3

Hence the best estimate for the average rate of change of function over the interval 1 ≤ x ≤ 3 is 3.

Chin canned a number of quart jars and a number of pint jars of tomatoes from his garden. A pint is 16 ounces and a quart is 32 ounces. The number of pints he canned is represented by p, and the number of quarts he canned is represented by q. Which equation models the scenario if Chin canned a total of 1,280 ounces? 1280 plus 16 p equals 32 q 1280 plus 32 q equals 16 p 32 q minus 16 p equals 1280 16 p plus 32 q equals 1280

Answers

Answer:

16 p plus 32 q equals 1280

16p + 32q = 1,280

Step-by-step explanation:

A pint = 16 ounces

A quart = 32 ounces

p = number of pints he canned

q = number of quarts he canned

if Chin canned a total of 1,280 ounces?

Total ounces canned = 1,280

Equation:

p × 16 ounces + q × 32 ounces = 1,280

16p + 32q = 1,280

The options:

1280 plus 16 p equals 32 q

1,280 + 16p = 32q

1280 plus 32 q equals 16 p

1,280 + 32q = 16p

32 q minus 16 p equals 1280

32q - 16p = 1,280

16 p plus 32 q equals 1280

16p + 32q = 1,280

The correct answer is

16 p plus 32 q equals 1280

16p + 32q = 1,280

Fiona can make 8 cards in 12 hour. She divides to find the number of cards she can make per hour, but she makes a mistake. Three of these reasons explain why her answer must be wrong. Which does NOT?

Answers

Answer:

2/3 card per hour

Step-by-step explanation:

The correct calculation is given below

The number of cards she can make per hour is :

12 hours = 8 cards

1 hour = x cards

Cross Multiply

12 hours × x cards = 8 cards × 1 hour

x cards = 8 cards × 1 hour/12 hours

x cards = 2/3 card

Answer:

Y=(1/2)x + 3

Step-by-step explanation:

The equation of the line is y = (1/2)x + 3.

We have,

The equation of a line is written as:

y = mx + c

Where m is the slope and c is the y-intercept.

Now,

From the line,

We have the following coordinates:

(2, 4) and (4, 5)

Now,

Slope.

m = (5 - 4) / (4 - 2) = 1/2

And,

(2, 4) = (x, y)

Substituting.

y = mx + c

4 = (1/2) x 2 + c

4 = 1 + c

c = 4 - 1

c = 3

Now,

y = (1/2)x + 3

Thus,

The equation of the line is y = (1/2)x + 3.

How do I find x in these equations

Answers

Answers:

Problem 9) x = 1Problem 10) x = 3Problem 11) x = 12Problem 12) x = 12

==============================================

Explanation:

For problems 9 through 12, we'll use the same set of steps. Recall that any parallelogram has the property that the adjacent angles are supplementary. This means close by angles add to 180. Each of the four diagrams show pairs of adjacent angles.

------------------

In problem 9, we have the following steps

(79x-1) + (102) = 180

79x + 101 = 180

79x = 180-101

79x = 79

x = 79/79

x = 1

------------------

Problem 10 is the same idea

(85) + (30x+5) = 180

30x+90 = 180

30x = 180-90

30x = 90

x = 90/30

x = 3

------------------

Problem 11

(55)+(9x+17) = 180

9x+72 = 180

9x = 180-72

9x = 108

x = 108/9

x = 12

------------------

Problem 12

(3x+12)+(132) = 180

3x+144 = 180

3x = 180-144

3x = 36

x = 36/3

x = 12

Answer:

9. X = 1

10. X = 3

11. X = 12

12. X = 12

Step-by-step explanation:

9.

1) 79x - 1 + 102 = 180

2) 79x + 101 = 180

3) Subtract 101 from both sides

4) 79x = 79

5) x = 1

10.

1) 85 + 30x + 5 = 180

2) 30x + 90 = 180

3) Subtract 90 from both sides

4) 30x = 90

5) x = 3

11.

1) 55 + 9x + 17 = 180

2) 9x + 72 = 180

3) Subtract 72 from both sides

3) 9x = 108

4) X = 12

12.

1) 3x + 12 + 132  = 180

2) 3x + 144 = 180

3) Subtract 144 from both sides

4) 3x = 36

5) x = 12

All answers have been checked by plugging the X back into the equation.

Step-by-step explanation:

We have completed the diagram with some lengths that come directly from the figure's symmetry.

Note the triangle formed at the left side of the trapezium is isosceles because it has an angle of 90° and another angle of 45°.

This means the base of the triangle has the same length as the height of 9.

This means the total base of the trapezium is x = 9 + 7 = 16

The right triangle must satisfy Pythagora's Theorem:

[tex]y^2=2*9^2[/tex]

[tex]y=\sqrt{2*9^2}[/tex]

Let's see

Firstly produce the line to Q such that it passes through and dives Q into two.

The interior angle of the Pentagon at the point Q=sum of its interior angle/5

The angle=540°/5=108°

That would make the exterior angle there=180°-108°=72°

Again,find the interior angle of the heptagon at the point Q=(sum of its interior angles)/7

Angle=900°/7=128.57°≈129°

That would make the exterior angle there=180°-129°=51°

Since Q was divided into the two exterior angles,we sum them up to obtain the angle value of Q

That is 51°+72°=123°
