Solve 1.1(3.4x-2.3)^2=15.5 and write it in ax^2+bx+c=0 form.

Answers

Answer 1

Answer:

In the normal ax² + bx + c format, this equation is expressed as:

12.716x² - 17.204x + 9.81 = 0

If we solve for x, it is approximately equal to both 178 and -0.43

Step-by-step explanation:

Let's reformat to ax² + bx + c = 0:

[tex]1.1(3.4x - 2.3)^2 = 15.5\\1.1(11.56x^2 - 15.64x + 5.29) = 15.5\\12.716x^2 - 17.204x + 5.819 = 15.5\\12.716x^2 - 17.204x + 9.81 = 0\\[/tex]

And now let's find the value of x

[tex]1.1(3.4x - 2.3)^2 = 15.5\\(3.4x - 2.3)^2 = 15.5 / 1.1\\(3.4x - 2.3)^2 = 14.09\\3.4x - 2.3 = \sqrt{14.09}\\3.4x = 2.3 \pm \sqrt{14.09}\\x = \frac{2.3 \pm 3.75}{3.4}\\x = (1.78, -0.43)[/tex]

Answer 2

Answer:

12.716x^2 -17.204x -9.681=0

ANSWER WITH EXPLANATION. BRAINLIST!!!!!

Answers

Answer:

1

Step-by-step explanation:

First, we have to make the fractions improper.

To this we would need to multiply the denominator by the whole number and add it to the numerator. 2*4 is 8.  8 + 5 is 13. So for the first fraction, it will be 13/5. Let’s do the second fraction. 2*4 is 8. 8 + 3 is 11. So for the second fraction, it will be 11/2. Since the fractions have the same denominator, we will not have to do anything to them. Now, all you have to do is simple subtraction. 13 - 11 is 2. Since the denominators are the same, it will equal to 2. So the final answer is 2/2 or 1.

Answer:

(5,-5)

Step-by-step explanation:

to find this out you would add them together and then divide by two:

(-5)+15= 10
10/2=5

(-18)+8=(-10)
-10/2=5

so your points would be 5,-5. you would add your x values and divide it by two and then your y values and divide them by two

whats the answer for (x) 1/2 (8x-6)=-1/3(9x-12)

Answers

Answer:

1/2(8x-6)=-1/3(9x-12)

We move all terms to the left:

1/2(8x-6)-(-1/3(9x-12))=0

Domain of the equation: 2(8x-6)!=0

x∈R

Domain of the equation: 3(9x-12))!=0

x∈R

We calculate fractions

(3x9/(2(8x-6)*3(9x-12)))+(-(-2x8)/(2(8x-6)*3(9x-12)))=0

We calculate terms in parentheses: +(3x9/(2(8x-6)*3(9x-12))), so:

3x9/(2(8x-6)*3(9x-12))

We multiply all the terms by the denominator

3x9

We add all the numbers together, and all the variables

3x^9

We do not support expression: x^9

What is the range of this function{(4,8), (9,2), (-3,-4)}

Answers

Answer:

8, 2, 4

Step-by-step explanation:

All the y values of a function are its range and all the x values are its domain

Since the y values of the functions are 8, 2, and -4. the range of this function{(4,8), (9,2), (-3,-4)} will be 8, 2, -4.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

All the y values of a function are its range and all the x values are its domain

All y's potential values are referred to as the function's range. Using the formula y = f(x), one may determine a function's range (x). If there is just one y value for each x value in a relation, then it is merely a function.

The y values of the functions are 8, 2, and -4.

Thus, since the y values of the functions are 8, 2, and -4. the ranges of this function{(4,8), (9,2), (-3,-4)} will be 8, 2, -4.
