Answer:

The required absolute equation is: |x-430|=20

The minimum and maximum acceptable soccer ball weights is 410 grams and 450 grams respectively.

Step-by-step explanation:

Consider the provided information.

The recommended weight of a soccer ball is 430 grams. The actual weight is allowed to vary by up to 20 grams.

Let x is the actual weight of the soccer ball.

The difference of actual weight and recommended weight can vary by 20 grams.

Thus, the required absolute equation is:

|x-430|=20

x-430=20 or x-430=-20

x=450 or x=410

The minimum and maximum acceptable soccer ball weights is 410 grams and 450 grams respectively.

For this problem, let's assign variable x to the value of the actual weight. The recommended weight is the central value of the range. So, the variation must be 20 grams below and above the recommended weight. The equation would be:

Actual weight = |Recommended weight +/- 20|
x = |430 +/- 20|

Evaluate x-y/5 when x is 23 more than 3 times y and y=6

posledela

Answer:

Step-by-step explanation:

1) "x is 23 more than 3 times y" is the same thing as "x = 23 + 3y"

REMEMBER: when you see "is" replace is with an equals sign.

2) Solve for x with your new equation.

3) Plug 6 into the y ("y = 6")

x = 23 + 3 x 6... x = 23 + 18... x = 41

4) Plug in your variables, and evaluate.

(41 - 6)/5... 35/5... 7!

Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let (x,y) be the unkno

spin [16.1K]

The other endpoint is (1, -17).

The midpoint formula is:

$m=(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Using our midpoint and endpoint, we have:
$(6, -11) = (\frac{11+x_2}{2}, \frac{-5+y_2}{2})
\\
\\6=\frac{11+x_2}{2} \text{ and } -11=\frac{-5+y_2}{2}
$

For the first equation (to find the x-coordinate) we will multiply both sides by 2:
$6\times2=\frac{11+x_2}{2}\times 2
\\
\\12=11+x_2$

Subtract 11 from both sides:
12 - 11 = 11+x₂ - 11
1 = x₂

For the second equation (the y-coordinate) we multiply both sides by 2:
$-11\times2=\frac{-5+y_2}{2}\times 2
\\
\\-22=-5+y_2$

Add 5 to both sides:
-22+5 = -5+y₂ + 5
-17 = y₂

This means that (x₂, y₂) is at (1, -17).
