Answer:
(-7, 4) and 7
Step-by-step explanation:
The standard equation of a circle is expressed as (x - a)^2 + (y - b )^2 = r^2
Where the center is the point (a, b) and the radius is r
Note: simply inserting the variables and playing around with your signs gives you the value for (a and b)
The square root of the radius gives you the value for r

Answer:
The three numbers are 12, 11, and 6
Step-by-step explanation:
Let
First Number be x
Second Number be y
Third Number be z
Now, we can come up with equations from the word problem.
The 2nd is 1 less than 1st means:
y = x - 1
3rd is 5 less than 2nd means:
z = y - 5
1st is TWICE as large as 3rd means:
x = 2z
We have 3 equations. Let's put 3rd into 1st, we get:
y = 2z - 1
Now put this into 2nd equation, we get:
z = 2z - 1 - 5
Solving for z:
5 + 1 = 2z - z
z = 6
We know x = 2z, so x = 2(6) = 12
x = 12
and y = x - 1, this means y = 12 - 1 = 11
y = 11
Step-by-step explanation:
9$ x 71 hours (rewritten) 9x 71 = 639
plus the commission
10% x 1,901$ (rewritten) .1 x 1,901 = 190.1
639 + 190.1 = 829.1
