Given the function g(x) = 8x − 2, compare and contrast g(−2) and g(4). Choose the statement that is true concerning these two va

kramer

Answer:

The value of g(−2) is smaller than the value of g(4).

Step-by-step explanation:

To solve this, simply plug in the values in the given equation g(x)=8x-2.

g(-2)=8(-2)-2 -----> -18

g(4)=8(4)-2 ------> 30

here it is obvious that -18 is smaller than 30, therefore the value of g(−2) is smaller than the value of g(4).

Kate and Jean paint a house together in 6 days. If they work alone, Kate takes 5 fewer days than Jean would take to do the same

dsp73

Answer: $x^2-17x+30=0$

Step-by-step explanation:

Let x = Time taken <em>(in days)</em> by Jean to do the job.

Then, Time taken by Kate to do the job = x-5

Then, together they will take time (t) as

$\dfrac{1}{t}=\dfrac{1}{x}+\dfrac{1}{x-5}$

$=\dfrac{x-5+x}{x(x-5)}=\dfrac{2x-5}{x(x-5)}$ .

$\Rightarrow\ t=\dfrac{x(x-5)}{2x-5}$

Since it is given that Kate and Jean paint a house together in 6 days.

i.e.

$6=\dfrac{x(x-5)}{2x-5}\\\\\Rightarrow 6(2x-5)=x^2-5x\\\\\Rightarrow\ 12x-30=x^2-5x\\\\\Rightarrow\ x^2-5x-12x+30=0\\\\\Rightarrow\ x^2-17x+30=0$

So, the equation represents the time it takes Kate to paint the house by herself is $x^2-17x+30=0$ .
