Answer: has a maximum
the maximum is 11
Step-by-step explanation:
f(x)= -5x^2-10x+6
the function f(x)= ax^2+bx+c=0 has a<0 so the equation has a maximum
I know V has the coordonate x=-b/2a, and y=-(b^2-4ac)/4a
b^2-4*a*c= (-10)^2-4*(-5)*6=100+120=220
so -b/2a=-(-10)/-2*5=+10/-10=-1 and
-(b^2-4ac)/4a=-220/4*(-5)=-220/-20=22/2=11
so V( -1, 11)
and the maximum is 11
Keeping in mind that complex solutions never come all by their lonesome, they always come with their sister
thus, "i" is not there all by herself, her sister is there too, namely the conjugate
so
i = 0+i and thus its conjugate sister will be 0-i
thus
3.687 x 10 with a small one above the 10
Answer:
-9
Step-by-step explanation:
-2x + 3 = -x + 12
move -x over by adding
-x + 3 = 12
move the 3 over by subtracting
-x = 9
divide by - to get the x positive
x = -9
If you are asking what to multiply on each side to get rid of 3/5 then you would do B. 5/3 but im not 100% sure if that is what you're asking
