J and k stands for two numbers.

1 answer:

8 0

2j = .5k

Let j = 5
2(5) = .5k
10 = .5k
divide both sides by .5
20 = k
When j = 5 , k = 20

The answer is c because if you do 7x60 you'll get 420 and 830-420=410 and 7x80 you'll get 560 and 970-560 is also 410.

Just multiply them together and get a4-2a2-24.
(a2-6)(a2+4)
F: a4
O:4a2
I:-6a2
L:-24
Add together

Answer:

yes they both are wrong

Step-by-step explanation:

Center of the Circle is (h,I) which is (4,-3)

so h= 4 and k = -3

radius is 4 units (3+1)

Equation for circle

$(x - h) {}^{2} + (y - k) {}^{2} = r {}^{2}$

substitute all the values in this equation

$(x - 4) { }^{2} + (y - ( - 3)) {}^{2} = 4 {}^{2} \\ (x - 4) {}^{2} + (y + 3) {}^{2} = 16$
