F(x) = 4(5) - 2 → f(x) = 20 - 2 → f(x) = 18
Answer:
x=139
Step-by-step explanation:
angles on a straight line add up to 180 degrees
Step-by-step explanation:
1. secx / cscx
2. sinx /cosx
Step-by-step explanation:
given x=2
and the equation

to find the value of q , you need to make q the subject in the equation as shown below
q= 3x-x -4
q=2x-4
but x= 2
so just substitute the value of x in the equation for the q

q=4-4
q=0
therefore the value of q is 0
