Answer:
(x+1)2+(y−2)2=5
Explanation:
The general form for a circle with center
(a,b) and radius r is XXX(x−a)2+(y−b)2=r2
With center (−1,2) and given that (0,0) is a solution (i.e. a point on the circle),according to the Pythagorean Theorem: XXX r 2=(−1−0)2+(2−0)2=5
and since the center is (a,b)=(−1,2)by applying the general formula we get:XXX(x+1)+(y−2)2=5
Step-by-step explanation:
its already in the answer
We need to assign a value for x to check the possible values of y.
1st inequality: y < -0.75x
X = - 1 ; y < -0.75(-1) ; y < 0.75 possible coordinate (-1,0.75) LOCATED AT THE 2ND QUADRANT
X = 0 ; y < -0.75(0) ; y < 0 possible coordinate (0,0) ORIGIN
X = 1 ; y < -0.75(1) ; y < -0.75 possible coordinate (1,-0.75) LOCATED AT THE 4TH QUADRANT
2nd inequality: y < 3x -2
X = -1 ; y < 3(-1) – 2 ; y < -5 possible coordinate (-1,-5) LOCATED AT THE 4TH QUADRANT
X = 0 ; y < 3(0) – 2 ; y < -2 possible coordinate (0,-2) LOCATED AT THE 4TH QUADRANT
X = 1 ; y < 3(1) – 2 ; y <<span> 1 possible coordinate (1,1) LOCATED AT THE 1ST QUADRANT
The actual solution to the system lies on the 4TH QUADRANT.

Substraction is a comutative operation
x + 3x + 4 = 72
4x + 4 = 72
4x = 68
x = 68 / 4
x = 17.
1,750 is the total cost of it.
Answer:
x=y
Step-by-step explanation:
because
6x=8y-2y
6x=8y
x=y
