lions [1.4K]

Answer:

Step-by-step explanation:

x=2,x-2=0

x=8

x-8=0

y=(x-2)(x-8)=x²-2x-8x+16=x²-10x+16

=x²-10x+25-25+16

=x²-10x+25-9

y=(x-5)²+9

axis of symmetry is x-5=0 or x=5

Which equation has a solution of k = 6.5?
olga_2 [115]
Answer:

-7k = -45.5

Explanation:

You can solve this by plugging in the “k” to the problems that are listed.
If you were to plug 6.5 in for all those problems, you’d get:

-3(6.5) = -19.5

-1 + 6.5 = 5.5

-7(6.5) = -45.5

-2 + 6.5 = 4.5

So, in this case, looking at the ones I answered and looking at the problems listed, the correct answer would have to be -7k = -45.5.

natima [27]
1 yards = 36 inches

3 × 36 = 108

1 foot = 12 inches

108 + 12 =120

So 3 yards and 1 foot is equal
to 120 inches

120 is greater than 100 so 3 yards and 1 foot is greater than 100 inches
