Find f(-2) f(x)=9x^2-5x+2
f(-2) means replace x in the equation with -2:
f(-2)=9(-2)^2-5(-2)+2
= 9(4) +10 + 2
= 36 +10 + 2
= 48
f(-2) = 48
<span>get all your x one on side and y on the opposing side
so we have
xdy=4ydx
dy/y=4dx/x
</span><span>integrate both sides
</span><span>lny=4lnx+C
</span><span> y=e^(4lnx+C)
</span><span>The answer is y=cx^4 </span>
Answer: (5+√2) and (3+√2)
Step-by-step explanation: Let (5+√2) and (3+√2) be two irrational numbers
Difference = (5+√2) - (3+√2)
Difference = 2
2 is a rational number
Answer:
y = 45/m^2 − 49/4
Isolate the variable by dividing each side by factors that don't contain the variable
