Answer:

C

Step-by-step explanation:

x²-14x-49=0

x²-14x+49=49+49

(x-7)²=98

(x-7)²=49×2

x-7=±7√2

x=7+7√2=7(1+√2)≈7(1+1.414)≈7(2.414)≈16.898≈16.9

or

x=7-7√2=7(1-√2)≈7(1-1.414)≈-7×0.414≈-2.898≈2.9

The equation f(x)=x−5 translated 4 units to the left is g(x)=
elixir [45]

The equation of the function g(x) is g(x) = x - 1

<h3>How to determine the equation of the function g(x)?</h3>

The given parameters are:

f(x) = x - 5

The above function f(x) is translated left by 4 units

So, we have

g(x) = f(x + 4)

This gives

f(x + 4) = x + 4- 5

Evaluate the sum

f(x + 4) = x - 1

So, we have:

g(x) = x - 1

Hence, the equation of the function g(x) is g(x) = x - 1

Rudik [331]

The height of the travel box version is 2 cm.

<h3>Dilation</h3>

Dilation is the increase or decrease in the size of a figure by a factor k to create and image. Both the figure and image are similar, hence the ratio of their corresponding sides are congruent.

Let h represent the height of the travel box, hence:

h / 8 = 306 / 1224

h = 2 cm

The height of the travel box version is 2 cm.

I THINK IT"S "C"

Your answer is no solutions.

Multiply the first equation by - 2.

- 2(3x - 2y = 6)
- 6x + 4y = -12

Combine the like terms of this equivalent equation and the original second equation.

- 6x + 4y = -12
6x - 4y = 14

Everything on the left side of the equal sign cancels out leaving you with:
0 ≠ 2

Because this statement is not true, it means there are no solutions to this system of equations.
