Answer:
A. y = 1/2 x.
Step-by-step explanation:
Use the point-slope form of a linear (straight line) function:
y - y1 = m(x - x1)
m = 1/2, x1 = 4 and y1 = 2, so:
y - 2 = 1/2(x - 4)
y = 1/2x - 2 + 2
y = 1/2 x (answer)
Answer:
Step-by-step explanation:
Remember:
![(\sqrt[n]{a})^n=a\\\\(a+b)=a^2+2ab+b^2](https://tex.z-dn.net/?f=%28%5Csqrt%5Bn%5D%7Ba%7D%29%5En%3Da%5C%5C%5C%5C%28a%2Bb%29%3Da%5E2%2B2ab%2Bb%5E2)
Given the equation 
, you need to solve for the variable "x" to find its value.
You need to square both sides of the equation:
Simplifying, you get:
Factor the quadratic equation. Find two numbers whose sum be 7 and whose product be -8. These are: -1 and 8:
Then:
Let's check if the first solution is correct:
(It checks)
Let's check if the second solution is correct:
(It does not checks)
Therefore, the solution is:

Step-by-step explanation:
Answer:
g(x) = | x + 7 |
Step-by-step explanation:
The absolute value graph f(x)=|x| is a V-shaped graph with the vertex (tip, point) at (0,0). The graph shown has been translated (slid, shifted) 7 units to the left. Left or right shifts, horizontal shifts, are caused by an adjustment to the x. Horizontal shifts are also maybe the opposite of your intuition. Left shifts, you ADD to x. Right shifts, you subtract from x.
This is a left shift, so adjust the x by inserting a +7
f(x) = |x|
g(x) = | x + 7 |
