Answer:
You can put this equation into point slope formula which is…
y-y1= m(x-x1)
Whilst m is slope
x1 and y1 (x1, y,1)
So in this case lets find the slope first.
Slope is calculated by y2-y1/ x2-x1
Can be any point.
7-(-1) / 1-(-3)
Which is
2
Slope is 2
So plug it in.
y-(-1)= 2(x-(-3)
Solve
y+1= 2x+6
isolate y
Y=2x+5
Your equation is y=2x+5
X^2-4x+4=-12y+24
(x^2-4x-20)/-12=y
quadratic => vertex is (-b/2a,f (-b/2a))
Note it is a minimum since coefficient a is positive
Answer:
x = 31.2
Step-by-step explanation:
x - 19.7 = -4.1
x = 15.6 --- add 19.7 to both sides to get rid of -19.7
x = 31.2 --- multiply both sides by 2 to get rid of
Answer:
The correct option is parallelogram ABCD is a rhombus, because the diagonal bisects two angles
Step-by-step explanation:
In triangle ABD:
∠B = ∠D
Thus AB=AC by the property of opposite sides of equal angles are equal
In triangle CBD
∠B = ∠D
Thus CB=CD by the property of opposite sides of equal angles are equal
Thus all four sides of quadrilateral ABCD are equal
And diagonal BD bisects the angles
So, it is a rhombus
Therefore the correct option is parallelogram ABCD is a rhombus, because the diagonal bisects two angles....
