What/where is the question you have for me?
Step-by-step explanation:
Answer:
9.268
Step-by-step explanation:
To find out if they are parallel we need to see if the gradient is the same, to do this we need to get y in terms of x:
assuming the first equation is x+y+7=0
y=-x-7
and
y=x-3
The gradient is the coefficient of x (the number infront of x)
For equation 1 the gradient is -1, and for number 2 it is 1, therefore they are not parallel.
However to check if they are perpendicular we need to see if their gradients multiply to equal -1.
-1*1=-1 therefore they are perpendicular
0.4x 0.4x 0.4 = (0.4)^3
Exponential form = (0.4)^3
