Answer:
What grade is this?
Step-by-step explanation:
Answer:
larger number is -5 and smaller one is -1
Step-by-step explanation:
x+y = -6
x = -6-y ....eqn i
x-y = -4...eqn ii
substituting eqn i in ii
x - y = -4
or, - 6 - y - y = -4
or, -6 - 2y = -4
or, - 2y = 2
so, y = -1
x + y = -6
x + (-1) = -6
so, x = -5
Answer:
The combined length is 61 inches
Step-by-step explanation:
Answer:
(x +1)^2 +(y +0.5)^2 = 22.25
Step-by-step explanation:
The center of the circle is the midpoint of the diameter, so is ...
(h, k) = ((-5, -3) +(3, 2))/2 = (-5+3, -3+2)/2 = (-1, -1/2)
The circle formula is then ...
(x -h)^2 +(y -k)^2 = r^2
(x -(-1))^2 +(y -(-1/2))^2 = r^2
We can find r^2 by substituting one of the points for (x, y).
(3 +1)^2 +(2 +1/2)^2 = r^2 = 16 +6.25 = 22.25
Then the circle equation is ...
(x +1)^2 +(y +0.5)^2 = 22.25
2³-4²
= 8-16
=-8
Hopefully this helps! Good luck! :)
