Answer:
-3
Step-by-step explanation:
An increase in x-value from 9 to 10 is an increase of 1 unit. The slope of -7 tells you that the corresponding change in y will by -7 units:
v = 4 -7 = -3
The value of v is -3.
_____
<em>Alternate solutions</em>
You can see this easily on a graph, or you can use the equation of the line. We have a point and a slope, so the point-slope form is useful.
y = m(x -h) +k
y = -7(x -9) +4
For x=10, the value of y is ...
v = -7(10 -9) +4 = -7 +4
v = -3
Answer:
1/4 for both
Step-by-step explanation:
2/8 -- you divide 2 by 2 you get 1, 8 divided by 2 is 4 -- 1/4
3/12 -- you divide 3 by 3 you get 1, 12 divided by 3 is 4 -- 1/4
** tip: what you do to one half of the fraction you have to do to the other
hope this helps!

Step-by-step explanation:
you do stuff and you get 4 - 20 i
Diagram D has the relative locations correct.
If I were to show the bearing in a straightforward manner, I'd mark the angle NPQ as 50° and forget about angle NQP. That is, the diagram would look like that of A, but with P and Q swapped.
Answer:
B
Step-by-step explanation:
a difference of cubes factors in general as
a³ - b³ = (a - b)(a² + ab + b²)
given
p³ - 343q³
= p³ - (7q)³ ← a difference of cubes , then
= (p - 7q)(p² + 7pq + 49q²) ← in factored form
