Answer:

True

Step-by-step explanation:

Best to use a graphing calculator or graph it onto paper, after you change Point A after it reflected over the x - axis. The rule for reflection over the x-axis is (x, y) ---> (x, -y), so all you would need to do is change the positive 3 (the y value of A) into -3. So A' = (1, -3)

LenaWriter [7]

<span>  x^2 +(x-4)^2 =20^2</span>

<span>  x^2 +(x-4)^2 =400</span>

x^2 +(x-4)^2 -400=0

factor:

2x^2-8x-384=0

Factor the 2 out of 2X^2

2(x-16) (x+12) =0

<span> Divide both sides by 2</span>

(x-16) (x+12) =0

X=16 , x=-12

<span> Number cannot be negative so x=16</span>

The equation for the line of best fit is f(x) ≠1. 8x ⒠5. 4 for the set of values in the table. A 2-column table with 7 rows.
AleksandrR [38]

The equation for the line of best fit, the good approximation for x when f(x) = 30 is 20.

Given that

The equation for the line of best fit is f(x) = 1.8x − 5.4 for the set of values in the table.

A 2-column table with 7 rows.

The first column is labeled x with entries 4, 5, 6, 6, 8, 9, 10.

The second column is labeled f(x) with entries 5, 2, 5, 6, 8, 7, 18.

We have to determine

Using the equation for the line of best fit, what is a good approximation for x when f(x) = 30?

According to the question

The quadratic regression equation can be expressed as;

\rm f(x) = 1.8x - 5.4

Then,

The approximation for x when f(x) = 30 is,

\rm f(x) = 1.8x - 5.4\\\\\rm 30= 1.8x - 5.4 \\\\ 1.8x= 30+5.4\\\\1.8x=35.4\\\\x = \dfrac{35.4}{1.4}\\\\x=19.67\\\\x=20 \ approx

Hence, the equation for the line of best fit, the good approximation for x when f(x) = 30 is 20.

A NUMBER , TRIPLE THAT NUMBER , AND 12 ARE ADDED THE RESULT IS 32
liraira [26]
If you want to find out what that number is, then let's call it n
n + 3n (Three times the number) + 12 = 32
Simplify
4n + 12 = 32
Subtract 12 from each side
4n = 20
Divide each side by 4
n = 5
