Answer:
an hour....
Step-by-step explanation:
Point slope form
y - y1 = m(x - x1)
Plug in the given
slope = -4
Point ( 4, 1)
y - 1 = -4(x - 4)
y - 1 = -4x +16
add 1 to both sides
y = -4x + 17
Hope this helps!
Answer:
44.08 or 44.1
Step-by-step explanation:
OK so the basics of this question is that for every 45 feet of the actual skyscraper we have 2 inches in the model. The first thing we do is divide 992/45 which equals 22.04. Know if this was 1 inch for every 45 feet we would be done however we need to multiply this number by 2 to get our answer so 22.04*2 =44.08
Answer:
A, C, E
Step-by-step explanation:
By analyzing the graph, we can see that the roots are
and
.
We now want to find all equations of the form
.
This immediately gives C as 1 answer.
We can expand our equation to find other possible solutions!
By the FOIL method: 
We can then divide both sides of the equation to find that
, so A is another answer.
We can complete the square on
to find the last possible solution.
.
We can then multiply both sides of the equation by
to find that
, so E is the last answer.
The proof that the other answers don't work is left as an exercise.
So, the answers are A, C, and E, and we're done!
