Answer:
y=-1 and x=-1
Step-by-step explanation:
10x/-10y=-1 y=-1 same with x=-1
here is a different equation
12x(-1)=(144/12y)=x and y
x=-y
y=-x
-y=-1y because if there is no variable it is 1 or -1 depending if its a - Symbol
same with -x=-1x
Bring all the terms to one side.
x^2+5x–5x –43 –6 = 0
x^2–49=0
x^2 = 49
x = +- 7
Hope I helped :)
Answer:
Step-by-step explanation:
A mixed number is an addition of its whole and fractional parts.
−(1 + 29/40)
Add
1 and 29/40
Write 1 as a fraction with a common denominator.
−(40/40 + 29/40)
Combine the numerators over the common denominator.
−40+29/40
Add 40 and 29
−69/40
The result can be shown in multiple forms.
Exact Form:−69/40
Decimal Form:−1.725
Mixed Number Form:−1 29/40
1/2x+y=-6 y=3/5x+5
substitute
1/2x+3/5x+5=-6
11/10x+5=-6
11/10x=-11
11x=-110
x=-10
Answer:
Option A. 
Step-by-step explanation:
we know that
The area of the rectangle is equal to
A=LW
where
L is the length of rectangle
W is the width of rectangle
we have
Plot the vertices
see the attached figure
L=AD=BC
W=AB=DC
the formula to calculate the distance between two points is equal to
<em>Find the distance AD</em>
substitute in the formula
<em>Find the distance AB</em>
substitute in the formula
Find the area
