This is the answer, let me know if something isn't clear
1. DE || AB - Given
2. DE 1/2 AB - side splitter theorem
3. CD/CA = CE/CB - sst = proportioned sides
Answer:
y=6x-2 is perpendicular to the 6y=-x+7
y=6x+1 is parallel to the y=6x-2
Step-by-step explanation:
if product of two lines gradient is -1 than lines are perpendicular
gr y=6x-2
y=mx+c m=gradient
1)m=6
2)m=-1/6
3)m=6
if gradients of 2 lines are equal they are paralel
A scale factor of 3 was used
Answer:
x = 6
y = 7
a = 1/4
Step-by-step explanation:
Equation 1:
2(3x+2) = 2x + 28
6x + 4 = 2x + 28
4x = 24
x = 6
Equation 2:
5y+13 = -43-3y
8y = -56
y = -7
Equation 3:
8a + 8 = 16 - 24a
32a = 8
a = 1/4
