G(2) = 2 + 4/3 = 10/3

f(g(x)) = f(g(2)) = (10/3)^2 + 20/3 + 3 = 187/9 = 20 7/9 answer

Let f(x)=4x+9. Write a function g whose graph is a reflection in the y-axis of the graph of f. g(x)= ?

frez [133]

Answer:

$g(x)=-4x+9$

Step-by-step explanation:

So we know that:

$f(x)=4x+9$

To reflect across the <em>y-axis</em>, instead of x, use -x. Therefore:

$g(x)=f(-x)=4(-x)+9$

Simplify:

$g(x)=-4x+9$

And that's our answer :)

(can u guys help me PLSSSSS ) A company sets sales goals for employees each month.

Pavlova-9 [17]

A. Kristina will sell 294 items in 28 days if she stays on her current pace.
B. She is not on track to meet the goal. By doing the math she would only sell around 294 items by day 28 when she needs to sell around 400 to reach her goal. if she keeps this pace she won’t reach that goal unless she is able to bump up her weekly count by 2-5 items then she can either hit the goal or go over.

Solve the rational equation (3x^2+1)/(x-1) + x =4 + 4/(x-1)

natita [175]

Answer:

The answer to your question is letter D

Step-by-step explanation:

Rational equation

$\frac{3x^{2} + 1}{x - 1} + x = 4 + \frac{4}{x - 1}$

Simplify

$\frac{3x^{2} + 1 + x(x - 1)}{x - 1} = \frac{4(x - 1) + 4}{x - 1}$

Cancel the denominators and expand

3x² + 1 + x² - x = 4x - 4 + 4

Simplify

4x² - x + 1 - 4x = 0

4x² - 5x + 1 = 0

Factor

4x² - 4x - 1x + 1 = 0

4x(x - 1) - 1(x - 1) = 0

(4x - 1)(x - 1) = 0

x₁ = 1/4 x₂ = 1
