Answer:
x=11
BC=19
Step-by-step explanation:
AB+AC=AC this is because B is in between A and C. So now we can substitute all of the line segments, so we have
x+2x-3=30 Now you add 2x and x
3x-3=30 Now you add 3 to both sides so you can get 3x alone on one side
3x=33 Now you divide both sides by 3 so you get the x alone on one side
x=11
The next step is to substitute x to find BC.
BC=2x-3 Substitute the x with 11
BC=2(11)-3 Then multiply 2 and 11 because that is the rule with parenthesis
BC=22-3 then subrtact the 3 from 22
BC=19
You can check your work by doing AB+BC=AC
11+19=30 substitute your answers and then add them together
30=30
Answer:
if f(x) = ax + b then f-1(x) = (x - b)/a
Step-by-step explanation:
Now
f(x)=ax + b
then y = ax + b
interchanging x and y , we get
or, x = ay + b
or, x - b = ay
or, (x - b)/a = y
therefore,f-1(x) = (x - b)/a

Answer:
4.5m/s^2
Step-by-step explanation:
Given data
Mass= 200kg
Force= 895N
Required
the acceleration a
We know that
F=ma
a= F/m
substitute
a= 895/200
a= 4.5 m/s^2
Hence the accelaration is 4.5m/s^2
