I think the first answer is x > 4, but I'm not sure, I need help with that. I don't know if there even is a second answer or

STALIN [3.7K]

Hi again!

|2x - 3| - 1 > 4

|2x -3| > 4 + 1

|2x -3| > 5

Now let's solve the absolute value

We know either 2x -3 >5 or 2x -3<-5

Let's solve the first possibility

2x - 3 > 5

2x > 5+ 3

2x > 8

x > 8/2

x> 4

Now solve the second possibility

2x - 3 < -5

2x < -5 + 3

2x < -2

x < -2/2

x< -1

Thus the correct answer is x > 4 or x < -1

I used an online graphing calculator

I hope this helps again!

(Please show all work) 1. Find f(6) if f(x)= 1/2x + x - 4

dsp73

Answer:

$\large\boxed{1.\ f(6)=5\ or\ f(6)=20}\\\boxed{2.\ d=5}\\\boxed{3.\ vertex=(-3,\ -1)}$

Step-by-step explanation:

$1.\\\text{Put x = 6 to the equation of a function}\ f(x):\\\\\text{If}\ f(x)=\dfrac{1}{2}x+x-4\to f(6)=\dfrac{1}{2}(6)+6-4=3+6-4=5\\\\\text{If}\ f(x)=\dfrac{1}{2}x^2+x-4\to f(6)=\dfrac{1}{2}(6^2)+6-4=\dfrac{1}{2}(36)+2=18+2=20\\\\2.\\\text{The formula of a distance between two points:}\\\\d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\\text{We have the points (2, -4) and (5, -8). Substitute:}\\\\d=\sqrt{(5-2)^2+(-8-(-4))^2}=\sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5$

$3.\\\text{The vertex formula of a parabola:}\\\\y=a(x-h)^2+k\\\\(h,\ k)-vertex\\\\\text{We have}\ y=(x+3)^2-1=(x-(-3))^2-1\\\\\text{Therefore the vertex is:}\ (-3,\ -1).$

the function f(x)= 0.11 x + 43 relates how much derek pays for phone service, f(x), to the number of minutes, x, used for intern

san4es73 [151]

Answer:
f(320)= how much Dereck pays for phone service if he calls 320 minutes.

F(320)=0.11(320)+43=35.2+43=78.2

Answer: the value of f(320) is $78.2 and it will be the cost of phone service for 320 minutes of international calls.
