3x - 5y = 5 ——> 6x - 10y = 10

6x - 10y = 10
x + 10y = 4
——————-
5x = 6
x = 1.2

1.2 + 10y = 4
10y = 2.8
y = 0.28

so, x = 1.2 and y = 0.28

hope this helps :)

An equation of a circle is given as (x + 6)² + (y − 7)² = 81. Find the center and radius of the circle. Show all work to receive

Center is (-6,7) and radius is 9. A circle with a center at (h,k) and a radius of r has the equation (x-h)^2 + (y-k)^2=r^2 so h= -6 k= 7 r is 9 you just work back wards, what two numbers multiplied gives you 81? Well 9

Negative one fourths times negative six elevenths

You multiply fractions simply by multiplying numerators and denominators with each other:

$-\dfrac{1}{4} \times \left(-\dfrac{6}{11}\right) = \dfrac{1 \times 6}{4 \times 11} = \dfrac{6}{44} = \dfrac{3}{22}$
