Answer:
The equation of the line is y = 4x + 13
Step-by-step explanation:
In this question, we want to write the equation of the line using the point slope form.
Mathematically, the point slope form can be represented as;
(y-y1) = m(x - x1)
where x1 = -2 , y1 = 5 and m which is the slope is 4
Plugging these values into the equation, we have;
(y-5) = 4(x - (-2))
y-5 = 4(x + 2)
y -5 = 4x + 8
y = 4x + 8 + 5
y = 4x + 13
As there are 81 tiles total, that makes your area 81. Being a square, that makes your area equation A=s^2. As you need a side, this makes your equation s=√A. Plugging in 81 as A, we get s=√81=9, so an edge has 9 tiles.
Answer:
k = -3
Step-by-step explanation:
1) Simplify
5+20k+7k=28k+8
2) Combine the k's
5+27k=28k+8
3) Subtract 27k on both sides
5=k+8
4) Subtract 8 on both sides
-3=k or k= -3
I would go with B but this is a tricky question. Hopefully i am correct.
Answer:
AC = 7.3 in
Step-by-step explanation:
tan(51°) = 9/AC
1.24 = 9/AC
AC = 9/1.24
AC = 7.26
