Step-by-step explanation:
You use the order of operations: PEMDAS.
Sooo...
4*6-8/4=
24-8/4=
24-2=
22
6a^2 - 2 -6 a -5a = 0
6a^2 -11 a - 2 = 0
a = 2 , a= -1/6
Answer:
9
Step-by-step explanation:
All you have to do is add them up so the answer would be 13.5
Answer:
see explanation
Step-by-step explanation:
first we calculate the slopes of EF and FG using the slope formula
m = 
with (x₁, y₁ = E (7, 7 ) and F (4, 8 )
=
=
= - 
repeat with (x₁, y₁ ) = F (4, 8 ) and (x₂, y₂ ) = G (2, 2 )
=
=
= 3
if 2 lines are perpendicular then the product of their slopes = - 1
here
×
= -
× 3 = - 1
then EF is perpendicular to FG
