What is the equation for the translation of x2 + y2 = 16 seven units to the right and five units up?
(x + 7)2 + (y – 5)2 = 16
(x - 7)2 + (y + 5)2 = 16
(x + 7)2 + (y + 5)2 - 16
(x - 72 + (y – 5)2 = 16

.

Step-by-step explanation:

The given circle has equation .

This is the equation that has its center at the origin with radius 4 units.

When this circle is translated seven units to the right and five units up, then the center of the circle will now be at (7,5).

The equation of a circle with center (h,k) and radius r units is .

This implies that, the translated circle will now have equation.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
