<span>Put up a graph or a chart, and suddenly everything you're saying makes sense! Graphs or charts help people understand data quickly. Whether you want to make a comparison, show a relationship, or highlight a trend, they help your audience "see" what you are talking about.

Hope this helps.

Point A, located at (-11,17) on the coordinate plane, is reflected over the x-axis to form point B. Then point B is reflected ov

zalisa [80]

Answer:

B = (-11, -17)

C = (11, -17)

Step-by-step explanation:

Reflection over the x-axis is accomplished by changing the sign of the y-coordinate:

(x, y) ⇒ (x, -y) . . . . . reflection over x-axis

Reflection over the y-axis is accomplished by changing the sign of the x-coordinate:

(x, y) ⇒ (-x, y) . . . . . reflection over the y-axis

B = (-11, -17)

C = (11, -17)

<em>Check</em>

Reflection over both axes negates both coordinates. It is equivalent to reflection over the origin, or rotation 180°.

A(-11, 17) ⇒ C(11, -17) . . . . . both coordinates change sign

Suppose you needed to subtract a from b but mistakenly subtract b from a instead. How is the answer you get related to the corre

I would assume you would get a negative number and a positive number either way, but they would be the same number just one is negative and one is positive
