Answer:
-9
Its in the format y=mx+b, where m is the slope and b is the intercept. Also since x is 0 at the y intercept, you could substitute 0 for x and see the intercept

Equation of the circle =
80 = ( x - 1)^2 + (y + 1)^2
Step-by-step explanation:
Center = (1 , -1)
Point = ( 5 , 7)
Eqn of a circle is
r^2 = (x - h)^2 + (y - k)^2
We are not given the radius of the circle, fortunately we are provided the information that the circle contains a point ( 5, 7), so we use the above information to find r
Using the center (1, -1)
h - 1
k - -1
r^2 = (x - 1)^2 + ( y - -1)^2
r^2 = (x - 1)^2 + (y + 1)^2
With the point ( 5,7)
x = 5
y = 7
r^2 = ( 5 - 1)^2 + ( 7 + 1)^2
= 4^2 + 8^2
= 16 + 64
= 80
r^2 = 80
r = square root of 80
r = 8.94
The r = 8.94 , which means the equation of the circle is
80 = (x - 1)^2 + ( y + 1)^2
Answer:
Step-by-step explanation:
Let x represent the number of cars that Jamie washes.
Let y represent the number of pies that Stella makes.
The amount of money needed by Jamie and Stella to sign up for the trip is $600 each
Jamie earns $25 for each car washed. This means that if he washes x cars, he would earn 25×x =$25x
Stella earns $15 for each pie made.
This means that if she makes y pies, she would earn 15×y =$15y
Part 1) The inequality is
25x greater than or equal to 600
Part 2)The inequality is
15y greater than or equal to 600
Part 3) Stella only has enough supplies to make 40 pies. Total amount made from 40 pies would be 40×15 = 600
Jamie's earnings is
25x greater than or equal to 600
Stella's earnings is
15y lesser than or equal to 600
Part 4) Maximum amount of money that Stella can earn is 15×40 = $600
Therefore, Stella can afford to sign up for the trip.
