Answer:
option a is correct.
Step-by-step explanation:
We have given the equation:
Squaring both sides of the above equation we get:
After simplifying the first step
After final simplification we get:
We are getting quadratic equation since, the degree in resultant is 2.
Therefore, option a is correct.
Answer:
If my calculations are correct.
Step-by-step explanation:
Answer:
a = 18.15
Step-by-step explanation:
Combine like terms on the left side of the equation first. Add 7 and 42, then subtract 32 from the answer you get, then subtract 32 from that answer. This is going by order of PEMDAS.
Remember PEMDAS: (numbers 3 & 4 and numbers 5 & 6 are solved from left to right)
After combining like terms on the left side, you get -15. Now combine like terms on the right side of the equation by adding 14.3 and 7.
Get -2a alone by subtracting 21.3 from both sides.
Divide both sides by -2.
In this equation, a should equal .
Answer:
f()=2x+1
Step-by-step explanation:
given f(x)=-4x+1................(1)
x= put in equ (1)
f(x)=-4x+1
f( ) =-4(
)+1
f()=2x+1 answer
