<span>If f(x)= 2x^2 -4x and g(x) = 5 – 2x, evaluate f(x) – g(x) for x = 5
you first plug in 5 for x in both equations...
(2(5)^2-4(5))=f(x)
5-2(5)=g(x)
now you evaluate...
(2(25)-20)-5-10
50-30-15
20-15=5
Answer:
5

R=-7, you have to put each answer in the equation, therefore; 21=42-3(-7) So you have to do multiplication (PEMDAS, if you arent aware of that acronym then it stands for the order of what to do with an equation, Parentheses get solved first, then Exponents, then multiplication, then division, then addition, then finally subtraction. Solving in that order will solve your answer correctly.) With -3 times -7 which gives you 21. Then you do 42 - 21 which equals 21. So 21 = 21.
Answer:
yes
Step-by-step explanation:
this is a function as there are no negative exponents/fractions as exponents/division in the function....this is in fact a binomial hope this helps!
3x+3=9
x=2
that way the answer is 9
Answer:
26.4° (nearest tenth)
Step-by-step explanation:


<em>Taking the inverse of sine on both sides:</em>

x= 26.4° (nearest tenth)
