Y=-7X-14<br> 1. What is the y-intercept of the graph of the given function? How do you know?
34kurt

Answer:

(0, -14)

Step-by-step explanation:

The y intercept of the graph of the function is at (0, -14)

In the equation y = mx + b, the constant b is the y value of the y intercept. In this equation, b is equal to -14, so this means the y intercept is at (0, -14).

We can also find the y intercept by setting x equal to 0, then solving for y.

Substitute 0 for x:

y = -7x - 14

y = -7(0) - 14

y = 0 - 14

y = -14

So, the y intercept is at (0, -14)

A group of church members chartered a bus for $832. After making the arrangements, 6 more members decided to join the excursion
g100num [7]
Let x = # of original members
Cost per person (originally) = 832/x
Cost per person after 6 more people = 832/(x+6)
Solve 832/x=832/(x+6) +6  (because the cost was reduced by 6 
Solve for x.
x = 26 or -32 (but x is number of members, so it can't be negative)
# of original members is 26.
Original cost is 832/26 = $32 per person.

What is the radius of the circle given by the equation (x-2)^2+y^2=14
Rainbow [258]
The general equation of a circle is
 (x-a) ^ 2 + (y-b) ^ 2 = r ^ 2
 for this case the values of a and b are
 a = 2
 b = 0
 The radius of the circle is
 r ^ 2 = 14
 r = (14) ^ (1/2) = 3.74
