What is the equation of the line that goes through the points (-5,-1) and (5,5)?
Margaret [11]

Answer:

y = 3/5 x + 2.

Step-by-step explanation:

Use the point-slope equation of a straight line:

y - y1 = m (x - x1) where m = the slope amd (x1, y1) is a point on the line.

Here:

m = (5- (-1)) / (5 - (-5))

= 6/10

= 3/5.

Substituting for m and  (5, 5):

y - 5 = 3/5(x - 5)

y - 5 = 3/5x - 3

y = 3/5 x + 2.

Patrick wants to play laser tag. It costs $9.00 per game and he gets a student discount of $10. Write an equation to represent t
Nana76 [90]

Answer:

T=9x-10

Step-by-step explanation:

Let x be the number of games

Cost of 1 game = $9

Cost of x games = 9x

he gets a student discount of $10.

So, Cost after discount = 9x-10

Let the total cost be T

So, T=9x-10

So, An equation to represent the total cost of playing laser tag including the discount is  T=9x-10

timama [110]

Answer:

A_s=179  \ yd

Step-by-step explanation:

Area of Circle can be calculated using following formula

A=\pi r^{2}

Where r is radius of circle

<u>Area of outer circle (r=11 yd)</u>

A_1=\pi (11)^{2}\\A_1=379.94 \ yd

<u>Area of inner circle (r=8 yd)</u>

A_2=\pi (8)^{2}\\A_2=200.96 \ yd

Area of shaded region

A_s=A_1-A_2

A_s=379.94-200.96\\A_s=179  \ yd
