Y = x + 3 . . . (1)
4x + y = 18 . . . (2)
Putting (1) into (2) gives
4x + x + 3 = 18
5x = 18 - 3 = 15
x = 15/5 = 3
x = 3
y = x + 3 = 3 + 3 = 6
Solution = (3, 6)
Answer:
equation;
Center (-4,2)
Radius is
Step-by-step explanation:
Since the x^2 and y^2 have the same coeffiecent this will be a circle in a form of
Where (h,k) is center
r is the radius
So first we group like Terms together
Add 7 to both sides
Since the orginal form of the equation of the circle has a perfect square we need to complete the square for each problem
and
so we have
To find our center, h is -4 and k is 2
so the center is (-4,2)
The radius is
So the radius is 3 times sqr root of 3.

Answer:
its 152 i know cause i just did this....
Step-by-step explanation:
Answer:
Your answer is 4x.
Step-by-step explanation:
Add 2+2
Combine your x's (like terms)
then you got 4 from 2+2
Add the leftover x so it makes 4+x then add it will give you 4x.
