How do You graph : y-10= -5x?
miv72 [106K]

Equation:

y - 10 = -5x

Solve:

(y - 10) + 10 = (-5x) + 10

y = -5x + 10

Remember the formula (Slope Intercept Form):

y = mx + b

m = Slope (Rise/Run)

b = Y-intercept

So your graph would look something like the attached image:

A 3 inch radius circle is drawn inside a 7 inch radius circle. If you throw a dart at these circles, what is the probability you
lorasvet [3.4K]

Answer:

Step-by-step explanation:

The first step is to determine the areas of the inner and the bigger circles.

The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

Considering the inner circle,

diameter = 148.4 cm

Radius = 3 inches

Area = 3.14 × 3² = 28.26 inches²

Considering the bigger circle,

Radius = 7 inches

Area = 3.14 × 7² = 153.86 inches²

The area between the bigger and inner circles is

153.86 - 28.26 = 125.6 inches²

Probability = number of favourable outcome/number of total outcome.

the probability you land inside the bigger circle but outside smaller circle is

125.6/153.86 = 0.82
