<h3>f(x) is equal to 4.5 when x = 1/2</h3>

<em><u>Solution:</u></em>

Given that,

y = f(x) = 9x

We have to find f(x) when x = 1/2

We can solve by substituting x = 1/2 in given function

f(x) = 9x\\\\Plug\ in\ x = \frac{1}{2}\\\\f(\frac{1}{2}) = 9 \times \frac{1}{2}\\\\f(\frac{1}{2}) = 4.5

Thus f(x) is equal to 4.5 when x = 1/2

Determine the next step for solving the quadratic equation by completing the square
GaryK [48]

Answer:

  • The two solutions are:           x=\frac{1}{2}+/-\frac{\sqrt{7} }{2}

  • The next and every step are below.

Explanation:

1. -3=-2x^2+2x    : Given (addition property / add - 3 to both sides)

2. -3 = - 2(x^2-x)    : Given (commom factor - 2)

3. -3-1/2=-2(x^2-x+1/4)

    To obtain the perfect square it was added the square of half of the coefficient of x: (1/2)² = 1/4, inside the parenthesis.

Since, the terms inside the parentthesis are multiplied by - 2, you have to add - 2 (1/4) = - 1/2 to the left side of the equation.

4. Now, you have that the trinomial x² - x + 1/4 is a square perfect trinomial which is factored as (x - 1/2)² and get the expression:

-7/2=-2(x-1/2)^2

5. Divide both sides by - 2 to get the next expression:

-7/4=(x-1/2)^2

6. The last step is to extract squere root from both sides of the equality:

(x-1/2)=+/-\sqrt{\frac{7}{4}}\\ \\ x-1/2=+/-\frac{\sqrt{7} }{2}\\ \\ x=\frac{1}{2}+/-\frac{\sqrt{7} }{2}

Snowcat [4.5K]
Well if it is marked 1/3 off, then you're actually paying 2/3 of it. 2/3 of 123. " of " means multiply 2/3 * 123 = 246/3 = 82 So it now costs $ 82

What is the equation of a line parallel to -x+3y=-6 that passes through 9,-1
Natali [406]

Answer:

{ \tt{ - x + 3y =  - 6}} \\ { \tt{3y = x - 6}} \\ { \tt{y =  \frac{1}{3}x - 2 }}

• For parallel line, their gradients are the same:

→ m = ⅓

• From general equation of a line;

→ \: { \tt{y = mx + c}} \\

• For the point (9, -1):

→ \: { \tt{ - 1 = (9 \times  \frac{1}{3} ) + c}} \\  \\→ \:  { \tt{ - 1 = 3 + c}} \\  \\ → \: { \tt{c =  - 4}}

therefore:

→ \: { \boxed{ \tt{y =  \frac{1}{3}x - 4 }}}
