7x + 3y = m

attashe74 [19]

7x + 3y = m

3y = m - 7x

y = (m - 7x) / 3

4( r + 3 ) = t

r + 3 = t / 4

r = ( t - 3 )/ 4

2x + b = w

2x = w- b

x = ( w - b ) / 2

x (1 + y) = 2

x = 2 / 1 +y

What is the rate of interest on a loan of $2,000, for 284 days, if the amount of interest is $93.37, using the exact interest me

Viefleur [7K]

Answer: Option (c) is correct. Rate of interest = 6% p.a.

Step-by-step explanation:

Given that,

principal amount = $2000(loan)

time period = 284 days

interest amount (SI) = $93.37

we have to calculate the rate of interest (i),

Simple interest(SI) = principal amount × rate of interest (i) × time period

93.37 = 2000 × i × $\frac{284}{365}$

i = $\frac{34080.05}{568000}$

i = 0.06

i = 6%

the center of a circle is on the line y=2x and the line x=1 is tangent to the circle at (1,6).find the center and the radius

Julli [10]

The radius and the center of the circle are 4 units and (1,2), respectively

<h3>How to determine the center and the radius?</h3>

The center of the circle is on

y = 2x and x = 1

Substitute x = 1 in y = 2x

y = 2 * 1

Evaluate

y = 2

This means that the center is

Center = (1, 2)

Also, we have the point of tangency to be:

(x, y) = (1, 6)

This point and the center have the same x-coordinate.

So, the distance between this point and the center is

d = 6 - 2

d = 4

This represents the radius

Hence, the radius and the center of the circle are 4 units and (1,2), respectively
