Answer:
100
Step-by-step explanation:
.15x + 23 = .10x + 28
Answer:
around 4.1
Step-by-step explanation:
x+a=3/4
Move a to the other side. Sign changes from +a to -a.
x+a-a=3/4-a
x=3/4-a or x=-a+3/4
Answer: x=3/4-a or x=-a+3/4
Answer:
(x - 5)^2 + y^2 = 225/4,
or you could write it as (x - 5)^2 + y^2 = 56.25.
Step-by-step explanation:
The factor form is
(x - h)^2 + (y - k)^2 = r^2 where the center is (h, k) and r = the radius.
So we have:
(x - 5)^2 + (y - 0)^2 = r^2
As the point (-1, 9/2) is on the line:
(-1 - 5)^2 + (9/2)^2 = r^2
r^2 = 36 + 81/4
r^2 = 225/4.
So substituting for r^2:
(x - 5)^2 + (y - 0)^2 = 225/4
(x - 5)^2 + y^2 = 225/4 is the standard form.
6/7...
12 divided by 2 = 6
14 divided by 2= 7
hope this helps!
