Answer:
- no question content
- (x, y) = (1/2, 4)
- (x, y) = (2, 10)
Step-by-step explanation:
1. No link, no question
__
2. Divide the first equation by 2 and substitute for y using the expression in the second equation.
2x +(4x+2) = 5
6x = 3 . . . . . . . . . subtract 2
x = 3/6 = 1/2 . . . . divide by2
y = 4(1/2) +2 = 4 . . . . substitute into the equation for y
The solution is (x, y) = (1/2, 4).
__
3. The solution using a graphing calculator is (x, y) = (2, 10). (see attached)

Scale Factor 2
Length = 6
Width = 8
Perimeter = 2(6+8)= 2(14) = 28
Area = 6 times 8 = 48.
Scale Factor 3
Length = 8
Width = 10
Perimeter = 2(8+10)= 2(18) = 36
Area = 8 times 10 = 80.
Scale Factor 4
Length = 10
Width = 12
Perimeter = 2(10+12)= 2(22) = 44
Area = 10 times 12 = 120.

Step-by-step explanation:
Just make m the subject m=fa
Let the longest side of ΔABC is c = 24 and the longest side of ΔXYZ is z = 60
The ratio of any pair of corresponding sides of these triangles is the same:
z/c = 60/24 = 2.5
x = 10 · 2.5 = 25
y = 20 · 2.5 = 50
The perimeter of ΔXYZ : 25 + 50 + 60 = 135 units
hc = 8
hz = 8 · 2.5 = 20
The area of ΔXYZ : 60 · 20 / 2 = 600 square units
