Answer:
y+4 = 9/4(x-3)
Step-by-step explanation:
m=slope and b=y-intercept (probably useful for later on in the school years)
y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point
Substituting in what we know
y--4 = 9/4(x-3)
y+4 = 9/4(x-3)
In the expression given, the "n" is referring to a certain term, in this case, it would be the 16th term. So in order to find the 16th term, all you have to do is substitute n as 16 in the expression, so the answer is
. So the 16th term of the sequence is -29.
Answer:
The word you are looking for is rotational symmetry and for that an octagon has orders of 8 (that is what you call the times it overlaps) I do not know what you mean on the swcong question
Step-by-step explanation:
A way of finding out how many orders a shape has of rotational symmetry is by getting some tracing paper and tracing the shape. You then put your pencil on the center of the shape and count how many time the shape overlaps
Answer:
Step-by-step explanation:
Start by setting the width = x.
Length is equal to x+20.
We know the cost of the land was $12 per square foot (area) and the cost of the fence around the perimeter is equal to $8 per foot. This gives us two equations we need to work with.
$12(x*(x+20)) + $8((2*x)+(2*(x+20))) = 10560. It looks a little difficult to read but as we distribute the cost throughout the equations, we see it start to take shape.
12(x^2+20x) + 8(2x+2x+40) = 10560
12x^2+240x+16x+16x+320 = 10560
12x^2+272x+320=10560
The roots of our equation here are x=20, and x = -128/3
Since we know that area is not negative, our answer is x=20.
Check the work: 12(20)^2 + 272(20) +320 = 10560
