The value fo k is $\frac{13}{2}$ . This is because c, the constant, is the y-intercept. The graph shows where the line intersects the y-axis, which is -3. So you substitute -3 with c. To find the value of k, plug in the coordinate with the x and y values and then solve for k.

Answer:

x = 2

Step-by-step explanation:

$\frac{1}{2} (x - 1) - \frac{1}{6} (x+1) = 0$

In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we divided by 2 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.

$\frac{1}{2} (x - 1) - \frac{1}{6} (x+1) = 0$

→ Expand the brackets

$\frac{1}{2} x- \frac{1}{2}-\frac{1}{6}x -\frac{1}{6} =0$

→ Multiply everything by 12 to make solving the equation easier

6x - 6 - 2x - 2 = 0

→ Simplify equation

4x - 8 = 0

→ Add 8 to both sides to isolate 4x

4x = 8

→ Divide by 4 on both sides to isolate x

x = 2

⇒ We can substitute x = 2 back into the equation to see if the solution is correct, if we get 0 on both sides then x = 2 is correct

$\frac{1}{2} (x - 1) - \frac{1}{6} (x+1) = 0$

⇒ Substitute in the values

$\frac{1}{2} (2-1)-\frac{1}{6} (2+1) = 0$

⇒ Simplify

$\frac{1}{2} (1)-\frac{1}{6} (3) = 0$

⇒ Simplify further

$\frac{1}{2} -\frac{1}{2} =0$

0 = 0

The solution x = 2 is correct

If g(x)=f(x)−1, then g(x) translates the function f(x) 1 unit _[blank]_. Which word correctly fills in the blank in the previous

Nataly [62]

Answer:

Down

Step-by-step explanation:

Given

$g(x) = f(x) - 1$

Required

The translation of f(x) that gives g(x)

Given that the relationship between 2 functions be:

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

This means that f(x) is translated b units downward to give g(x). <em>So, the word that completes the blank is down</em>
