Circle a has center of (6, 7), and a radius of 4 and circle b has a center of (2, 4), and a radius of 16. what steps will show that circle a is similar to circle b? translate circle a using the rule (x + 4, y + 3). rotate circle a 45° about the center. dilate circle a by a scale factor of 4. reflect circle a about the origin.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

answer:

c) the x-coordinate of the center of the circle increases by 3
