That's Roman numerals but it is 1636 not as Roman numerals hope I helped
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
8.
33 = 2y + 1 + y - 1
Add the 1 and -1
Add the y and 2y
33 = 3y
11 = y
9, AQ = 2y + 1
2(11) + 1
22 + 1
23
AQ = 23
10, QX = y - 1
QX = 11 - 1
10
QX = 10
11. 62 = 3x - 4 + 3x - 4
Add -4 and -4
Then add 3x + 3x
62 = 6x
Divide 62 by 6x
x = 11 2/3
AB = 3x - 4
3 (11 2/3) - 4
3 * 11 2/3 = 35
35 - 4 = 31
AB = 31
Both sides are equal, so BC also equals 31
12. 206 = 3x - 4 + 3x - 4
206 = 6x
x = 34 1/3
AB = 3x - 4
AB = 3(34 1/3) - 4
AB = 103
Because AB and BC are the same, BC also equals 103.
Simplify the following:
k - 2 (k - (2 - k)) - 2
-(2 - k) = k - 2:
k - 2 (k + k - 2) - 2
Grouping like terms, k + k - 2 = (k + k) - 2:
k - 2 ((k + k) - 2) - 2
k + k = 2 k:
k - 2 (2 k - 2) - 2
-2 (2 k - 2) = 4 - 4 k:
k + 4 - 4 k - 2
Grouping like terms, k - 4 k - 2 + 4 = (4 - 2) + (k - 4 k):
(4 - 2) + (k - 4 k)
k - 4 k = -3 k:
-3 k + (4 - 2)
4 - 2 = 2:
Answer: 2 - 3 k
