Answer:
y ≥ 4x − 5
Step-by-step explanation:
using the point (2,4)
when x = 2 then y =4
y ≥ 4x − 5
4 ≥ 4(2) - 5
4 ≥ 8 - 5
4 ≥ 3
How big is the target in compound archery?
The target in a compound event is set at 50 metres. The target face is 80cm in diameter with the innermost 10-point ring 8cm in diameter. A barebow is the most primitive form of bow in archery, with archers allowed no stabilisers or sight pins to shoot at their targets.
If the corresponding sides of two similar triangles have congruent angles than the sides correspond to each other
in triangle abc
and triangle def
ab:de
bc:ef
ca:fd
so they correspond in ratio but are not necessarily congruent
if in the similar triangles the sides are equal than the angles will correspond in ratio to add up to 180 degrees
so if triangle abc≈ triangle def
then
∠abc:∠def
∠bca:∠efd
∠cab:∠def
Answer:
f⁻¹(x) = -(x+4) / 5
Step-by-step explanation:
Given function is :
f(x) = -5x-4
We have to find the inverse of given function.
Step 1. Put y = f(x) in given function
y = -5x-4
Step 2. Add 4 to both sides of above equation
y+4= -5x-4+4
y+4 = -5x
Step 3.Divide by -5 to both sides of above equation
y+4 / (-5) = -5x / (-5)
-(y+4) / 5 = x
Step 4 . Swap sides
x = -(y+4) / 5
Step 5. Put x = f⁻¹(y) in above equation
f⁻¹(y) = -(y+4) / 5
Step 6. replace y with x
f⁻¹(x) = -(x+4) / 5 which is the inverse of f(x) = -5x-4.
