Answer:

Reflection

Step-by-step explanation:

Given in the picture are some trapezoids.

Of these we find that trapezoids 1 and 2 are on either side of the x axis with same dimensions.

By seeing the shape and size of trapezoid on the graph, we find that the reflection would map trapezoid to trapezoid 2.

I need help with 14 and 15!?

Levart [38]

Answer:

Step-by-step explanation:

Pythagorean theorem states that the hypogenous of a right triangle is $c=\sqrt{a^{2}+b^{2}}$ . The hypogenous is the longest part of the triangle which is directly across from the 90 degree angle.

a = 9

b = 12

so,

$c = \sqrt{9^{2}+12^{2} } = 15$

George wrote an integer. The opposite of George's integer is - 53. Which of these statements about George's integer must be true

Readme [11.4K]

Answer:

D I and IV

Step-by-step explanation:

The opposite of an integer "x" is "-x".

I. The integer is 53. → Since the opposite of George's integer is -53, the integer is -(-53) = 53

II. The integer has an absolute value of - 53. → The absolute value of 53 is 53.

III. The integer is - 53. → It was 53, found in I.

IV. The integer has an absolute value of 53. → It has an absolute value of 53, found in II.

Any of these please I’m having difficulty

frosja888 [35]

Answer:

864 squared meters

Step-by-step explanation:

Set up a proportion. The scale between 270 and 360 should be the same as 648 to the fourth yard.

$\frac{270}{360} = \frac{648}{x}\\270x = (360)(648)\\270x = 233280\\x = 864 m^2$

8xy= 2(2x + y) solve for y

STatiana [176]

Answer: $\displaystyle y= \frac{2\text{x}}{4\text{x} - 1}$

============================================

Work Shown:

$8\text{x}y= 2(2\text{x} + y)\\\\8\text{x}y= 4\text{x} + 2y\\\\8\text{x}y - 2y= 4\text{x}\\\\y(8\text{x} - 2)= 4\text{x}\\\\y= \frac{4\text{x}}{8\text{x} - 2}\\\\y= \frac{2*2\text{x}}{2(4\text{x} - 1)}\\\\y= \frac{2\text{x}}{4\text{x} - 1}\\\\$

---------------

Explanation:

The idea is to first get all the y terms to one side. I did this by subtracting 2y from both sides in the third step.

Then factor out y and divide both sides by (8x-2)

Afterward there's the optional steps of simplifying (as shown in the final two steps).
