Answer:
x^2 + y^2 - 8x + 18y + 48 = 0
Step-by-step explanation:
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the centre of circle and r is the radius of circle. hence the standard form of equation can be obtained by expanding
(x-4)^2 + {y-(-9)}^2 = 7^2
The first one is 3:6, or 1:2 in simplest form. There are three hammers for every six screw drivers.
The second one is 2:8, or 1:4. I am not sure if they want you to actually count each banana, but if so, that would be the answer. For every 2 apples, there are 8 bananas. If you are not supposed to count the bananas, it would be 2:2, or 1:1.
The third one is 15:100, or 3:20 in simplest form. For every 15 sixth grade teachers, there are 100 sixth grade students.
Hope this helps!!! :)))
Answer:
$8.50/h
Step-by-step explanation:
I am unsure of the - in the equation. This should be 4h+50+6h+70=M
then we would set the equation equal to the $205
205=4h+50+6h+70
if we simplify we have
205=10h+120
then we would get the h by itself and we get
205-120=10h
85.00=10h
85.00/10=10h/10
8.50=h
