Mathematics
1 answer:
iVinArrow [24]2 years ago
6 0

Answer:

A' (1, -4)

B' (-4, -2)

C' (-5, 4)

D' (-2, 1)

Step-by-step explanation:

When reflecting a point across the x-axis, the x-coordinate remains the same, but the y-coordinate becomes its additive inverse.

The additive inverse of a number is simply the opposite of a number.

So, to reflect this quadrilateral across the x-axis, we must change the coordinates.

Remember: When reflecting a point across the x-axis, <u>the x-coordinate remains the same, but the y-coordinate becomes its additive inverse.</u>

Point A: (1, 4) ⇒ A' (1, -4)

Point B: (-4, 2) ⇒ B' (-4, -2)

Point C: (-5, -4) ⇒ C' (-5, 4)

Point D: (-2, -1) ⇒ D' (-2, 1)

Which of the following has a value this is less than zero? A:(-6)^2 B:1/3 x 2 C:0.5^2 D:-7^2
solniwko [45]

The value of -7² is less than zero which is the correct answer would be an option (D)

<h3>What is the fraction?</h3>

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

<h3>What are Arithmetic operations?</h3>

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

To determine the value is less than zero

Option A: (-6)² ⇒ 36

So this value is greater than zero

Option B: 1/3 × 2 ⇒ 2/3

So this value is greater than zero

Option C: 0.5² ⇒ 0.25

So this value is greater than zero

Option D: -7² ⇒ -49

So this value is less than zero

Determine whether the relationship is an inverse variation or not. Explain.
kolbaska11 [484]

Answer: The product xy is not constant, so the relationship is not an inverse variation.

Step-by-step explanation:

For it to be an inverse variation, the product of x and y must be constant.

  • For the first row, xy=2(424)=848.
  • For the second row, xy=3(280)=840.
  • For the third row, xy=4(210)=840.

This means <u>the product xy is not constant, so the relationship is not an inverse variation.</u>
