Find the value of x

Doss [256]

Answer:

x = 40

Step-by-step explanation:

The three angles in a triangle add to 180 degrees

x + 30 + (3x-10) = 180

Combine like terms

4x +20 = 180

Subtract 20 from each side

4x+20-20 = 180-20

4x= 160

Divide each side by 4

4x/4 =160/4

x = 40

Let the graph of g be a translation 5 units up followed by a reflection about the y−axis of the graph of f(x)=6x. Write a rule f

yan [13]

Reflections and translations are instances of transformation.

The rule of function g for the given reflection and translation is $g(x) =-6x + 5$

Given

$f(x) = 6x$

The rule of translating 5 units up is:

$(x,y) \to (x,y+5)$

So, we have:

$f'(x) = f(x) +5$

$f'(x) = 6x +5$

The rule of reflecting about the y-axis is:

$(x,y) \to (-x,y)$

So, we have:

$g(x) =f(-x)$

$g(x) =6(-x) + 5$

$g(x) =-6x + 5$

Hence, the rule of function g is: $g(x) =-6x + 5$

What is the value of the expression 2x² – 5x + 6 when x = -2?

Svet_ta [14]

Answer:

24 is correct answer

Step-by-step explanation:

$2 {x}^{2} - 5x + 6 \\ = 2 {( - 2)}^{2} - 5 \times ( - 2) + 6 \\ = 2 \times 4 + 10 + 6 \\ = 8 + 10 + 6 \\ = 24$

hope it helped you:)

The water in a reservoir decreased by 47% during a drought. Before the drought, the reservoir held 44,580 acre ft (AF) of water.

RSB [31]

44,580 x 47 %

44,580 x .47 = 20,952.6

So, the water decreased 20,952.6 ft

If you want the water level after the drought just subtract.

44,580 - 20,952.6 = 23,627.4 ft

Hope this helps. :)
