Circle = (x-h)^2 + (y-k)^2 = r^2

Center is (h,k) h = -5, k = 2
Radius is 4, r = 4

(x - -5)^2 + (y - 2)^2 = 4^2
(x + 5)^2 + (y - 2)^2 = 16

Find the equation of the line that is parallel to the given line and passes through the given point. y=0,5x-2;(-2,1)
Mashcka [7]

Answer:

y = 0.5x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 0.5x - 2 ← is in slope- intercept form

with slope m = 0.5

Parallel lines have equal slopes, thus

y = 0.5x + c ← is the partial equation

To find c substitute (- 2, 1) into the partial equation

- 1 = - 1 + c ⇒ - 1 + 1 = 0

y = 0.5x + 0 , that is

y = 0.5x ← equation of parallel line

24. Anton borrowed $460 for a new bicycle. He made 9 monthly payments to repay the loan. He paid $60 interest. What is his simpl
hodyreva [135]

Answer:

17.4%​

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E is the interest amount, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time, in year.

In this question:

He borrowed $460, so P = 460

Paid $60 interest, so E = 60

9 months. So t = \frac{9}{12} = 0.75

We have to find I.

E = P*I*t

60 = 460*I*0.75

I = \frac{60}{460*0.75}

I = 0.174

So the correct answer is:

17.4%​
