X/2x+5=x-2/2x-1
X(2x-1)=(2x+5)(x-2)
2x²-x=2x²-4x+5x-10
-x+4x-5x=-10
-2x=-10
X=5



Then x=5

I REALLY NEED HELP, PLEASE HELP !! WORTH 30 POINTS !!
valina [46]

Answer:

2/9

Step-by-step explanation:

y=6(3)^x

Let x =-3

y = 6 * 3^-3

Remember negative exponents move it from the numerator to the denominator

y = 6 *1/3^3

y = 6 * 1/27

y = 6/27

y = 2/9

Find the dimensions of the rectangle with area 289 square inches that has minimum perimeter, and then find the minimum perimeter
nalin [4]
 <span>To minimize the perimeter you should always have a square. 
sqrt(289) = 17 
The dimensions should be 17 X 17 

To see , try starting at length 1, and gradually increase the length. 
The height decreases at a faster rate than the length increases, up until you reach a square. 

Or if you want to use algebra, Say the width is 17-x 
Then the length is 289/(17-x) 

Now, this is bigger than 17+x, as shown here: 
289/(17-x) > 17+x 
289 > 289 - x^2 
which is true. 
so the perimeter would be bigger than 2 * (17- x + 17 + x) = 2 * (2 * 17) = 4 * 17 

Again, the dimensions should be a square. 17 X 17.</span>

What is the length of the missing leg of a right triangle given a leg of length 8 and a hypotenuse of length 10. Leave your answ
bezimeni [28]

Answer:

6

Step-by-step explanation:

The hypotenuse will always be equal to "c." You can put "a" or "b" as 8. This gives us a^2 + 8^2 = 10^2 which simplifies to a^2 + 64 = 100. From there, you simplify (subtract 64, giving you a^2 = 36, and then take the square root of a^2 & 36 to get a = 6 (because 6*6 = 36))
