Answer:

The value of the equation for x is x=\frac{58}{9} .  

Step-by-step explanation:

Consider the provided equation.

3(x - 5) + 2 (3x + 1) = 45

Open the parentheses.

3x - 15 + 6x + 2 = 45

Now add the like terms.

3x +6x- 15+ 2 = 45

9x- 13 = 45

Add 13 from both sides.

9x- 13+13= 45+13

9x= 58

Divide both the sides by 9.

\frac{9x}{9}=\frac{58}{9}

x=\frac{58}{9}

Hence, the value of the equation for x is x=\frac{58}{9} .

Answer:

6.444.... or 6&4/9

Step-by-step explanation:

3(x-5)+2(3x+1)=45<------distributive property

3x-15+6x+2=45    <------combine like terms

9x-13=45              <------addition property of equality

9x=58                   <------division property of equality

x=6.444...

If (x+1,10)=(4,2y) then find the value of x &amp; y
lawyer [7]

Answer:

<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>3</u></em><em><u> </u></em><em><u> </u></em><em><u>&</u></em><em><u> </u></em><em><u>y</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>5</u></em></h2>

Step-by-step explanation:

<h3><em><u>Given</u></em><em><u>, </u></em></h3>

(x+1, 10) = (4, 2y)

<u>First</u><u> </u><u>x</u><u> </u><u>coordinate</u><u>, </u>

x + 1 = 4

=> x = 4 - 1

=> <em>x = 3 (Ans) (i)</em>

<u>Second</u><u> </u><u>y</u><u> </u><u>coordinate</u><u>, </u>

10 = 2y

=  > y =  \frac{10}{2}

=> <em>y</em><em> </em><em>=</em><em> </em><em>5</em><em> </em><em>(</em><em>Ans</em><em>)</em><em> </em><em>(</em><em>ii</em><em>)</em>

Please help! Its for my big test tomorrow!
Aloiza [94]

Answer:

# The transformation of f(x) to be g(x) is

- Reflected across the x-axis

- Translated 7 units to the left

- Translated 6 units up

# The transformation of f(x) to be g(x) is

- Reflected across the y-axis

- Translated 7 units down

Step-by-step explanation:

* Lets revise some transformation rules

* Lets talk about the transformation

- If the function f(x) reflected across the x-axis, then the new

 function g(x) = - f(x)

- If the function f(x) reflected across the y-axis, then the new

 function g(x) = f(-x)

- If the function f(x) translated horizontally to the right  

 by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

* Lets solve the problems

# f(x) = 2^x ⇒ g(x) = -(2)^(x + 7) + 6

- There is a -ve sign in-front of the 2

∵ f(x) will be -f(x)

∴ f(x) will reflect across the x-axis ⇒ (1)

- The power x becomes x + 7

∵ -f(x) will be -f(x + 7)

∴ -f(x) will translate 7 units to the left ⇒ (2)

- after that -f(x + 7) add by 6

∴ -f(x + 7) will translate 6 units up ⇒ (3)

- From (1) , (2) , (3)

∴ The transformation of f(x) to be g(x) is

- Reflected across the x-axis

- Translated 7 units to the left

- Translated 6 units up

# f(x) = ㏒(x) ⇒ g(x) = ㏒(-x) - 7

- The (x) will be (-x)

∵ f(x) will be f(-x)

∴ f(x) will reflect across the y-axis ⇒ (1)

- after that f(-x) subtracted by 7

∴ f(-x) will translate 7 units down ⇒ (2)

- From (1) , (2)

∴ The transformation of f(x) to be g(x) is

- Reflected across the y-axis

- Translated 7 units down

* For more understand look to the attached graphs

# First function:

- f(x) is the red

- g(x) is the blue

# Second function:

- f(x) is the black

- g(x) is the green

The perimeter of th triangle shown is 32ft.
azamat

32 = 12 1/4 + 6 1/3 +x

get a common denominator for the fraction, 12

32 =  12 (1/4 * 3/3) + 6 1/3*4/4 + x

32 = 12 3/12 + 6 4/12 + x

add

32 = 18 7 /12 + x

subtract 18 7/ 12 from each side

32 - 18 7/12 = x

borrow from 32

31 12/12 - 18 7/12 = x

13 5/12 =x

Choice A
