17 =k
Step-by-step explanation:
is means equals
51÷3 = k
17 =k
The vertex is at (2, 5).
To find the vertex, we first find the axis of symmetry; this is given by
x = -b/2a
For our equation, b = -16 and a = 4:
x = -(-16)/2(4) = 16/8 = 2
We substitute this back into our equation:
y = 4(2)² - 16(2) + 21 = 4(4) - 32 + 21 = 5
Therefore the vertex is at (2, 5).
Hello :
x²-x-2 = (x+1)(x-2)
x²-x-2 = 0 : x+1 =0 or x-2 = 0
x= -1 or x= 2 are the zero of f(x)
Answer:
210 candy bars
85 gum
Step-by-step explanation:
$200=0.75cb+0.50gum
cb+gum=295
gum=295-cb
substitute
$200=0.75cb+0.50(295-cb)
$200=0.75cb+147.5-0.50cb
$200=0.25cb+147.5
0.25cb=52.5
cb=210
gum=295-210=85
