Answer:
y = 3/8x + 1/8
Step-by-step explanation:
The slope of a perpendicular line is the opposite and reciprocal of the original slope.
-8/3 -> 3/8
Find the new y-intercept.
y = 3/8x + b
2 = 3/8(5) + b
2 = 1.875 + b
0.125 = b
y = 3/8x + 1/8
Best of Luck!
Step-by-step explanation:
it clearly consists of 2 rectangles and 1 triangle (as you tried correctly to point out by drawing the separating lines).
we only need to calculate all 3 areas and add them up for the total.
the area of a rectangle is
length × width
so, in our 2 cases we have
6 × 2 = 12 km²
5 × (3 + 2 + 3) = 5×8 = 40 km²
the area of a triangle is
baseline × height / 2
in case of a right-angled triangle the 2 sides enclosing the 90° angle can be used as baseline and height.
so, in our case
6 × (5 + 2 + (3 + 2 + 3 - 2)) / 2 = 6×(7 + 6)/2 = 3×13 = 39 km²
in total, the whole area is
12 + 40 + 39 = 91 km²
Answer:
x = 5
y = 4
Step-by-step explanation:

Answer:
The value of f(x) when x=-1 is 0.5
Therefore 
Step-by-step explanation:
Given that y=f(x)=
to find the f(x) when x=-1 :
That is to find f(-1)
Put x=-1 in the given function f(x)=



Therefore 
The value of f(x) when x=-1 is 0.5
The answer would be 7.42
