Answer:

x = {9, -3}

Step-by-step explanation:

  • 2| x-3| - 5 = 7
  • 2| x-3|  = 12
  • | x-3| = 6
  • x - 3 = ± 6
  • ⇒ x= 3+ 6= 9
  • ⇒ x= 3 - 6= -3

Or it can be shown as:

  • x= {9, -3}

How do I solve and whats the answer?
8090 [49]

Answer:

x = -6

Step-by-step explanation:

Here we have an equilateral triangle.  All three sides have the same length, 2.  Therefore, the interior angles are all equal to 60 degrees.

Therefore, 6 - 9x = 60, and -9x = 54.  Dividing both sides by -9 results in

x = -54/9, or x = -6.

Question 1:
AnnyKZ [126]

Answer(1):

Given that h(y)=2y-7.

h(8) means  plug y=8 into h(y)=2y-7.

h(8)=2*8-7=16-7=9

Hence C) 9 is the final answer.


Answer 2:

(7/8) = (m/32)

to solve for m, we begin by cross multiply

8m=7*32

8m=224

m=28

Hence choice C) 28 is final answer.


Reflection symmetry occurs when a line is drawn to divide a shape in halves so that each half is a reflection of the other.


Rotational symmetry is to check if the given picture is symmetric after some rotation.


Answer 3:

Letter "E" will have

B) the letter has reflection symmetry only

So B) is correct.


Answer 4:

Which statement is true?

Letter "Z" will have

B) the letter has rotation symmetry only

Hence B) is correct.


Answer 5:

Letter "X" will have

A) the letter has both reflection and rotation symmetry

Hence A) is correct.

Find inverse of f(x)=x^3-9<br>Not sure of my answer!​
Katyanochek1 [597]

as you may already know, to get the inverse of any expression, we start off by doing a quick switcheroo on the variables, and then solve for "y".

\bf \stackrel{f(x)}{y}=x^3-9\implies \stackrel{\textit{quick switcheroo}}{\underline{x}=\underline{y}^3-9}\implies x+9=y^3\implies \sqrt[3]{x+9}=\stackrel{f^{-1}(x)}{y}
