Answer:
15-44+32= 3
Step-by-step explanation:
Write the vertex form of the equation and find the necessary coefficient to make it work.
.. y = a*(x +3)^2 -2
.. = ax^2 +6ax +9a -2
You require the y-intercept to be 7. So, for x=0, you have
.. 9a -2 = 7
.. 9a = 9
.. a = 1
The equation you seek is
.. y = x^2 +6x +7
The answer is A- between 8 m& 12m
Answer:
It could be 32:40.
Step-by-step explanation:
There is a constant ratio 4:5 with the ribbons in the boxes, so with a table you would go down multiplying both the numbers by the same to get the answer...
(4:5 x 2 = 8:10... x 3 = 12:15...x 4 = 16:20...etc.)
