What is the vertex of y=-6(2.5-x)(x-5.5)?

Alex787 [66]

Hello :

 y=-6(2.5-x)(x-5.5) = -6(2.5x -13.75 -x² +5.5x)
y = -6(-x²+8x -13.75)
y = 6x²-48x+82.5
note :
if f(x) = ax²+bx +c the vertex is the point : ( -b/2a ; f(-b/2a))
a=6 b=-48 c = 82.5 .......calculate
-b/2a = -(-48)/2(6)= 4
f(4) =6(4)²-48(4)+82.5 =96 - 192 +82.5 = -13.5

Use substitution to solve the following system of equations.

Diano4ka-milaya [45]

$d+e-f=-3 \\
e=f+d+7 \\
f=2e-6 \\ \\
\hbox{substitute 2e-6 for f in the 2nd equation and solve for e:} \\
e=2e-6+d+7 \\
e=2e+d+1 \ \ \ |-2e \\
-e=d+1 \ \ \ |\times (-1) \\
e=-d-1 \\ \\
\hbox{substitute -d-1 for e in the 3rd equation and solve for f:} \\
f=2(-d-1)-6 \\
f=-2d-2-6 \\
f=-2d-8$

$\hbox{substitute -d-1 for e and -2d-8 for f in the 1st equation and solve for d:} \\
d+(-d-1)-(-2d-8)=-3 \\
d-d-1+2d+8=-3 \\
2d+7=-3 \ \ \ |-7 \\
2d=-10 \ \ \ |\div 2 \\
d=-5 \\ \\ e=-d-1=-(-5)-1=5-1=4 \\ \\
f=-2d-8=-2 \times (-5)-8=10-8=2 \\ \\
\boxed{d=-5} \\ \boxed{e=4} \\ \boxed{f=2} \\
\hbox{answer D}$

Plz solve this question mhanifa

IrinaK [193]

Answer:

Option D

Step-by-step explanation:

Given:

f(x) = 1/ (x - 3)
g(x) = $\sqrt{x+5}$

The composite function f · g(x) is:

f(g(x)) = 1 / ( $\sqrt{x+5} - 3$ )

Restrictions are:

x + 5 ≥ 0 ⇒ x ≥ - 5

and

$\sqrt{x+5}$ ≠ 3 ⇒ x + 5 ≠ 9 ⇒ x ≠ 4

Combination of the above gives us the domain:

x ∈ [ - 5, 4) ∪ (4, +∞)

Correct choice is D
