Solve for x and y 9/x-4/y=8

borishaifa [10]

You can solve <span>9/x-4/y=8 for x or for y but NOT at the same time.

Solving for x: </span><span>9/x-4/y=8 Mult all 3 terms by xy to eliminate the fractions.

9(xy)/x - 4xy/y = 8xy => 9y - 4x = 8xy, or 9y = 4x + 8xy = 4x(1+2y)

then 9y = x [ 4(1+2y) ]
9y
therefore x = ------------
4(1+2y)

Solve for y using a similar approach.

Which value must be added to the expression x2 + 12x to make it a perfect-square trinomial?

denis23 [38]

36 is must be added to the expression x² + 12x to make it

perfect-square trinomial

Step-by-step explanation:

The perfect-square trinomial x² + 2ax + a² = (x + a)², then

1. The first term in the trinomial is square the 1st term in the bracket

2. The middle term in the trinomial is the product of 1st , 2nd

terms of the bracket and 2

3. The 3rd term in the trinomial is square the 2nd term in the bracket

∵ The expression is x² + 12x

∵ We must add the 3rd term which make it perfect-square trinomial

- Divide 12x by 2 to find the product of the 1st term and 2nd term

in the bracket

∵ 12x ÷ 2 = 6x

∴ The 1st term is x and the 2nd term is 6 of the bracket

∵ The 3rd term in the trinomial is square the 2nd term in the bracket

∴ The 3rd term in the trinomial is 6² = 36

∴ x² + 12x + 36 = (x + 6)²

36 is must be added to the expression x² + 12x to make it

perfect-square trinomial

Find the distance between each pair of points

dolphi86 [110]

Answer: the correct answer is 20

Step-by-step explanation:

The formula for determining the distance between two points on a straight line is expressed as

Distance = √(x2 - x1)² + (y2 - y1)²

Where

x2 represents final value of x on the horizontal axis

x1 represents initial value of x on the horizontal axis.

y2 represents final value of y on the vertical axis.

y1 represents initial value of y on the vertical axis.

From the graph given,

x2 = - 7

x1 = 5

y2 = - 7

y1 = 9

Therefore,

Distance = √(- 7 - 5)² + (- 7 - 9)²

Distance = √(- 12²) + (- 16)²

= √(144 + 256) = √400

Distance = 20

borishaifa [10]

Answer:

1. The weights of wrestlers on the team varies by 74 lbs. range

2. The most popular M&M's color is green. mode

3. The mean price for an mp3 download is $1.96. mean

4. Half of the students in 3rd hour PE are 15 or older. median

Step-by-step explanation:

1. The weights of wrestlers on the team varies by 74 lbs. This is the range, the difference between the maximum and the minimum value.

2. The most popular M&M's color is green. This is the mode, the value more repeated.

3. The mean price for an mp3 download is $1.96. This is the mean.

4. Half of the students in 3rd hour PE are 15 or older. This is the median, the value in the half of the values

Find the slope of the graphed line

Anna [14]

Answer:

4

Step-by-step explanation:

Pick two points on the line

(0,-5) and (1,-1)

We can find the slope using

m = (y2-y1)/(x2-x1)

= ( -1 - -5)/(1 - 0)

(-1+5)/(1-0)

4/1

= 4
