A circle with the equation (x + 6)2 + (y + 3)2 = 16 is reflected over the line x = 2.

fomenos

Answer: $(x-10)^{2}+(y+3)^{2}=16$

Step-by-step explanation:

We know the center of the original circle is (-6, -3). After reflecting this over the line x=2, the new center is now (10, -3).

Thus, the equation of the circle is $(x-10)^{2}+(y+3)^{2}=16$ .

mina [271]

Answer:

e = 6

Step-by-step explanation:

10e - 2e - 9 = 39

8e - 9 = 39

8e = 48

e = 6

CHECK:

10(6) - 2(6) - 9 = 39

60 - 12 - 9 = 39

39 = 39

It would be option D because a dilation means an increase in size, where as a translation, rotation, and reflection are all movements that does not increase it size, so it will remain congruent

On a winter morning, the temperature before sunrise was -10℉. The temperature then rose by 1℉ each hour for 7 hours before dropp

Artemon [7]

Answer:

The temperature after 10 hours is -9 ºF.

Step-by-step explanation:

This statement can be translated mathematically as follows. The temperature after 10 hours from sunrise is:

$T = -10\,^{\circ}F + \left(1\,\frac{^{\circ}F}{h} \right)\cdot (7\,h)+ \left(-2\,\frac{^{\circ}F}{h} \right)\cdot (3\,h)$

$T = -9\,^{\circ}F$

The temperature after 10 hours is -9 ºF.
