Answer:
y+2-x=0
Step-by-step explanation:
Here,
(-3,-5)=(x1,y1)
(3,1)=(x2,y2)
Slope(m)=y2-y1/x2-x1
=1-(-5)/3-(-3)
=1+5/3+3
=6/6
=1
Mid point=(x1+x2/2 , y1+y2/2)
=(-3+3/2 , -5+1/2)
=(0/2 , -4/2)
=(0 , -2)
Now, (0,-2)=(x1,y1)
Equation:
y-y1=m(x-x1)
y+2=1(x-0)
y+2=1x
y+2-x=0 is the required equation.
Answer:
600ft square
Step-by-step explanation:
Lets multiply all numbers given by 10 beacuse they represent 10 ft
20ft*30ft=600ft square` the area of living room
25ft*20ft=500ft square` the area of bedroom
Answer:
Number of term N = 9
Value of Sum = 0.186
Step-by-step explanation:
From the given information:
Number of term N =
Number of term N =
Number of term N = 9
The Value of the sum can be determined by using the expression for geometric series:
here;
m = 5
n = 9
r = 0.5
Then:
Answer:
7 )
x =
8 )
Step-by-step explanation:
7 ) 8)
In Δ ABC In Δ XYZ
∠ C = 45° ∠ X = 60°
∠ A = 90° ∠ Y = 90°
To Find :
x = ?
y = ?
Solution:
We Know
In Δ ABC
∠ C = 45°
∠ A = 90°
∴ ∠ B = 45° ......Angle sum property of a triangle i.e 180°
∴ Δ ABC is an Isosceles Triangle
∴ AC = AB = x =
Now appplying Trignometry identity we get
Now In Δ XYZ
∠ X = 60°
∠ Y = 90°
∴∠ Z = 30° . .....Angle sum property of a triangle i.e 180°
Now appplying Trignometry identity we get
Now,
