Answer:

Step-by-step explanation:

to find the x-intercepts put y=0

x²+6x+8=0

x²+4x+2x+8=0

x(x+4)+2(x+4)=0

(x+4)(x+2)=0

x=-4,-2

so x - intercepts are (-4,0) and (-2,0)

How do I get the ans??

ioda

Answer:

11 sets of forks

Step-by-step explanation:

First subtract 406-278 to find total amount of forks needed which is 128 forks.

Then divide 128 by 12 to see how many sets of forks you need.

You get 10.67 but because you can't buy two thirds of a set, you have to round up to 11 sets of forks.

Hope this helps :)

Do rational expressions contain logarithmic functions? A. always B. sometimes C. never

bazaltina [42]

The right answer is C. never

The quotient of two algebraic expressions is a fractional expression. Moreover, the quotient of two polynomials such as:

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

is called a rational expression. So according to this definition rational expressions does not contain logarithmic functions. In fact, a rational expression is an expression that is the ratio of two polynomials like this:

$f(x)=\frac{P(x)}{Q(x)} \\ \\ with \ Q(x) \neq 0$

Rosie is a real estate agent and is paid the following for commission on sales: 4% for the first $50,000, 2% for the next $100,0

Elena-2011 [213]

Answer:

22,000

Step-by-step explanation:

4%/100=0.04

0.04*50,000=20,000 || 130,000-50,000=80,000 ||

2%/100=0.02

0.02*100,000= 2,000 || 80,000 - 100,000 ||

To explain it simply, Rosie receives 20,000 in commission for the first 50,000 of the sale. However, she sold a property for 130,000 meaning she also receives 2,000 for the next 100,000. Therefore she receives $22,000 in total on her $130,000 sale.
