Answer:

$\frac{5}{1-x}$

Step-by-step explanation:

Given

$\frac{3}{1-x}$ - $\frac{2}{x-1}$

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

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

= $\frac{5}{1-x}$

A thief steals an ATM card and must randomly guess the correct pin code that consists of four digits (0 through 9) that must be

stiv31 [10]

The lowest value he'd be able to produce is 0000. The highest value he'd be able to produce is 9999. This means that the thief would have to select the correct pin out of 10,000 combinations. So his chances of selecting the correct pin on his first try would be:

1/10,000

{1 out of 10,000}

write the slope-intercept form of the line with a slope of 2 and a y-intercept of -4. include your work in your final answer.

IgorLugansk [536]

I cant really show you how to graph this but i can try to explain it. you would make a 4 quadrant graph and do rise over run.
1)start by making the graph
2) on the line of the graph marked Y is where you would put -4
3) From -4, you would go up (rise) by 2 and go over to the right 1 where you end is the slop

I'm assuming you didn't mean to repeat each number 3 times.

If she did 184 jumping jacks in 4 minutes that means she did 46 jumping jacks per minute.

Find all solutions to 4sin(5x) = 4 between 0 and 360°. (Give your answer in degrees.)

Step2247 [10]

Answer:

when n=0, x=18°

when n=1, x= 90°

when n=2 x=18+72*2=162°

when n=3, x=18+72*3=234°

when n=4, x=18+72*4=306°

or

x= 18 + 72n, when n={0,1,2,3,4}

Step-by-step explanation:

4sin(5x) =4

sin(5x) = 1

sin(α) = 1, when α=90° + 360n

5x = 90° +360n

x= 18 + 72n

when n=0, x=18°

when n=1, x= 90°

when n=2 x=18+72*2=162°

when n=3, x=18+72*3=234°

when n=4, x=18+72*4=306°

when n=5, x°=18+72*5 = 378°

General answer : x= 18 + 72n, when n={0,1,2,3,4}
