Point a, located at (-11,-7) on the coordinate plane, is reflected over the x-axis to form point b. then point b is reflected over the y-axis to form point c. what are the coordinates of b and c?

B (-11,7)

C (11,7)

Step-by-step explanation:

The coordinates of point A are (-11,-7).

If the point is reflected over the x-axis to form point B then, the x coordinate will remain the same and the y coordinate will change by sigh only.

So, coordinates of point B will be (-11,7)

Now, point B is reflected over the y-axis to form point C.

Hence, the y coordinate of point C will remain the same as point B and the x coordinate of point B will change by its sign only.

Therefore, the coordinates of point C will be (11,7). (Answer)

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
