Answer:

(d) k = 8

Step-by-step explanation:

The value k in the equation ...

g(x) = f(x) +k

represents a vertical translation by k units.

The vertex coordinates for f(x) and g(x) are ...

f(x): vertex = (-3, -3)

g(x): vertex = (-3, 5)

This means ...

f(-3) = -3

g(-3) = 5 = f(-3) +k = -3 +8 ⇒ k = 8

_____

<em>Additional comment</em>

Translations of various kinds are often most easily seen by comparing points where the graph has a distinctive feature. On this graph, that is the vertex.

Does anyone know how to do thesubstitution method?

Angelina_Jolie [31]

Hi!

<h3>How do we use the substitution method?</h3>

To solve using the substitution method, we first want to isolate any of the variables from one of two equations, and then you take the value of that and plug it into the other equation.

<h3>Given:</h3><h3> $y=4x-10$ </h3>

$y=-3x+4$

Normally, our step one would be to pick a variable and isolate it, but it looks like we already have the y-value in both equations isolated! So our step one is already done!

Plug the isolated variable into the other equation.

We will use the value of y in the first one, and plug it into the second.

The value of y is "4x - 10", so we will change "y" in the second equation to "4x - 10", like so:

$4x-10=-3x+4$

<h3>Step Three:</h3>

Algebra!

You should be familiar with how to solve equations.

So:

$4x-10=-3x+4$

Add 10 to both sides:

$4x=-3x+14$

Add 3x to both sides:

$7x=14$

Divide both sides by 7:

$x=2$

Now, take the x value and plug it into one of the other equations and solve for y.

$y=4(2)-10$

$y=8-10$

$y=-2$

Therefore, our answer is (2, -2).

What is the value of x

azamat

Answer:

x = 20

Step-by-step explanation:

given a line parallel to a side of a triangle and intersecting the other two sides, then it divides those sides proportionally , that is

$\frac{10}{5x+10}$ = $\frac{11}{121}$ = $\frac{1}{11}$ ( cross- multiply )

5x + 10 = 110 ( subtract 10 from both sides )

5x = 100 ( divide both sides by 5 )

x = 20
