Answer:

Option B is correct

y = -75x+640

Step-by-step explanation:

The equation of line is given by:

y=mx+b

where, m is the rate or slope and b is the initial amount.

As per the statement:

Wanda has $640 in her checking account.

She pays her landlord $75 per week for rent.

Assume that the number of weeks be x.

Let us assume that the y represented the money in the account after x weeks.

then;

the function becomes,

y = 640-7x

or

y = -75x+640

Therefore, the function best models the linear relationship is, y = -75x+640

The answer is y = 640 - 75x
As her balance starts at a fixed point ( 640)
and decrease every x weeks by 75
Hope it helps

Artist 52 [7]

Answer:

The statement is always TRUE

Step-by-step explanation:

An equilateral triangle has all angles and all sides equal

The sum of angles in a triangle is 180 degrees.

Let each of the angles be x degrees.

Then we solve the following equation for x.

x+x+x=180\degree

\implies 3x=180

\implies x=\frac{180}{3}=60\degree
