Answer:
B [2,∞)
Step-by-step explanation:
Answer: The coordinates of D are Option c (1,-2)
<u>explanation: </u>
The Parallelogram is a quadrilateral whose opposite sides are equal and parallel. The location of a parallelogram on a coordinate plane is determined based on its four vertices.
A coordinate plane is a two-dimensional plane formed by the intersection of two lines one is a vertical line and the other is horizontal. The vertical line is the y-axis and horizontal line x-axis.
Four points of parallelogram ABCD are A(-2,4),B(1,3), C(4,-1), D(1,-2)

|z+7|=12/3
|z+7|=4
z+7=4
-(z+7)=4
solve the first equation:
z+7=4
z=-3
solve the second equation:
-(z+7)=4
z=-11
z=-11,-3
Answer:
Step-by-step explanation:
“y varies directly as x”
y = kx
Plug in (4, 1.25) and solve for k:
1.25 = 4k
k = 1.25/4 = 0.3125
The equation becomes
y = 0.3125x
Answer:
b= -3
x= -2
x= -7
n = -6
Step-by-step explanation:
3b+7-1=-3
3b = -3 -7 +1
3b = -10+1
3b= -9
b = -9/3
b= -3
3x+1-6x=7
-3x = 7-1
-3x= 6
x= -6/3
x= -2
312=-6(7x-3)
312 = -6*7x +6*3
312= -42x +18
312-18= -42x
294 = -42x
x= -294/42
x= -7
-4(4n-8)=128
-4*4n +4*8 =128
-16n +32 = 128
-16n= 128-32
-16n = 96
n=-96/16
n = -6
