  210 + 115.5 = 325.5

2) 210×55 = 11550

   11550÷100 = 115.5

Find g(x), where g(x) is the translation 8 units left of f(x)=x
Olegator [25]

Using translation concepts, it is found that function g(x) is given by:

g(x) = x + 8.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, function g(x) is a translation 8 units left of f(x) = x, hence x -> x + 8 and:

g(x) = f(x +8) = x + 8.

Solve the quadratic equation for x. What is one of the roots? (x + 6)^2 = 49
stich3 [128]

Answer:

x equals -1 and it also equals -13. They are both considered the roots.

Step-by-step

  1. (x+6)^2= 49    to get rid of the exponent square root each side of the equation.
  2. (x+6)= √49     Find square root of 49.
  3. (x+6)= ±7        It could be positive 7 or -7 because both of them squared equal 49. Now solve for each possible equation, (x+6)= 7 and  (x+6)=-7.
  4. (x+6)=7  subtract 6 from each side.
  5. x= 1
  6. (x+6)=-7  Subtract 6 from each side.
  7. x=-13
  8. So the answers are -13 and 1.
