Answer:
Y=2x+7
Step-by-step explanation:
To find the gradient of the line u have to subtract the y intercepts and the x intercepts
11--9/2--8=20/10=2
Y-11/x-2=2
Y-11=2(x-2)
Y-11=2x-4
Y=2x-4+11
Y=2x+7
Area of a square: side^2
Area of a circle: (pi)(radius^2)
A(square)=(10x)^2
A(circle)=(pi)(2x)^2
A(square)=100x^2
A(circle)=(pi)4x^2
Shaded Area=A(square)-A(circle)
Shaded Area=100x^2-(pi)4x^2
=4x^2(25-(pi))
let L be <span>Lissette's age

Answer:
4/3
Step-by-step explanation:
x + 6 - (x + 2) / 3
= x - x + 6 - 2 / 3
= 4/3
Answer:
c). y + x = 0
Step-by-step explanation:
The locus is a line perpendicular to the line connecting the 2 points and passing through the centre of the line.
The mid-point of the line connecting the given points is:
(a + b + a - b)/2 , (a - b + a + b) / 2
= (a, a)
It's slope = (a + b)- (a - b) / (a - b)- (a + b)
= 2b/ -2b
= -1
So the slope of the line we want is -1/(-1) = 1.
Using the point-slope form of a line:
y - y1 = m(x - x1)
y - a = 1(x - a)
y - a = x - a
x + y = 0
