A group of friends is roping off a soccer field in a back yard. A particular full-size soccer field is a rectangle with a length

of 100 yards and a width of 50 yards. To fit the field in the back yard, the group needs to reduce the size of the field so its perimeter is 60 yards.
What is the Area of the soccer field in the back yard?

Answer:

200 ft

The original perimeter would be 300, so divided by 5, it would be 60. 100/5 is 20, 50/5 is 10. 20*10 is 200.

Six decreased by 9 times a number is -39
Andrew [12]

The translation of the mathematical statement given as six decreased by 9 times a number is -39 is 9x - 6 = -39

<h3>How to translate the mathematical statement?</h3>

The mathematical statement is given as:

six decreased by 9 times a number is -39

9 times a number means

9 * x (assume x is the number)

So, we have:

six decreased by 9 times a number is -39 ⇒ six decreased by 9x is -39

Decreased by means we subtract 6 from 9x.

So, we have:

six decreased by 9 times a number is -39 ⇒ 9x - 6 = -39

Hence, the translation of the mathematical statement given as six decreased by 9 times a number is -39 is 9x - 6 = -39

Triangle XYZ has vertices X(2,4), Y(3,4) and Z(3,8). Suppose you reflect this across the y-axis, then dilate it with a scale fac
mel-nik [20]

Answer:

X'' (-4, 8)

Y'' (-6, 8)

Z'' (-6, 16)

Step-by-step explanation:

The rule for reflecting across the y-axis is (x, y) -> (-x, y)

When you dilate by a scale factor of 2 about the origin, multiply each coordinate point by 2.

X (2, 4) -> (-2, 4) -> (-4, 8)

Y (3, 4) -> (-3, 4) -> (-6, 8)

Z ( 3, 8) -> (-3, 8) -> (-6, 16)

Use factoring to solve the quadratic equation. Check by substitution or by using a graphing utility and identifying x-intercepts
MaRussiya [10]

9514 1404 393

Answer:

  x = -7, x = 9

Step-by-step explanation:

We presume your equation is ...

  x² -2x -63 = 0

Factors of -63 that have a sum of -2 are -9 and +7. Then the factored equation is ...

  (x -9)(x +7) = 0

Solutions make the factors zero.

  x -9 = 0   ⇒   x = 9

  x +7 = 0   ⇒   x = -7

The solutions to the quadratic equation are x = -7 and x = 9.
