Answer:
e║f.
Step-by-step explanation:
1) the pointed vectors of the given lines are:
for line e: (3-10;5-8)=(-7;-3);
for line f: (10-3;4-1)=(7;3);
2) -7/7=-3/3=-1, it means the lines are parallel.
Your answer should be 52.8
Answer:
y=3x-5
Step-by-step explanation:
parallel means that both lines share the same gradient.
from the equation y=3x-12 , we can deduce that the gradient is 3 because it is in the gradient-intercept form
now substitute values into formula
y-y1=m (x-x1)
y--2=3 (x-1)
expand brackets and simplify
y+2=3x-3
subtract 2 from both sides of equation
y=3x-5

Answer:
Lanza is correct.
Step-by-step explanation:
The two missing dimensions on the left are 4.5 m on the vertical line, and 5 m on the horizontal line.
These dimensions let us partition the garden a number of ways. One way is ...
- a rectangle 9 m by 4.5 m
- a rectangle 4 m by 3.5 m
The total of the areas of these is ...
(9)(4.5) +4(3.5) = 40.5 +14 = 54.5 . . . . square meters
At £16 per square meter, Lanza's charge will be ...
£16 × 54.5 = £872
Lanza is correct that she will have to charge more than £800.
