1 answer:

8 0

In order to solve for a nth term in an arithmetic sequence, we use the formula written as:

an = a1 + (n-1)d

where an is the nth term, a1 is the first value in the sequence, n is the term position and d is the common difference.

THIRD
A3=4+(3-1)(-5)
A3 = -6

A(3)=-2(3-1)(-5)
A3 = 20

FIFTH
A5=4+(5-1)(-5)
A5 = -16

A(5)=-2(5-1)(-5)
A5 = 40

TENTH
A10=4+(10-1)(-5)
A10 = -41

A(10)=-2(10-1)(-5)
A10 = 90

Choose the equation that matches this proportional relationship. The variable x represents length in meters and the variable y r

The correct answer should be x=100y. This is because y is centimeters and x is meters. It takes 100 cm to make 1m so it takes 100y to make 1x.

Answer:

I am pretty sure it is D.

Step-by-step explanation:

Town A is semetrical, meaning that if you fold it exactly in half it would match up. Town B. Is positively skewed, meaning that there is one or more point(s) to the right. (Negatively skewed means the same thing, but to the left instead of the right)

Lunna [17]

So basically here is the answer mate!

2x + 7y = 3-------------------------(substitute x's value here, i.e., x = -4y)

2( -4y ) + 7y = 3

-8y + 7y = 3

-1y = 3

y = -3------------------------( 1 )

Since x = -4y

= -4 ( -3 ) --------------------------( since we found the value of y)
