a=6 b=12
Step-by-step explanation:

Seventy-three percent is the same as
73% ,
.73 , and
.
A) The given equation has no solution. The absolute value cannot be negative, but must be -9 in order for the equation to be satisfied.
b) |x -7| = 2 . . . . . . . the equation
Solution 1:
-2 = x -7
5 = x . . . . . . add 7
Solution 2
x -7 = 2
x = 9 . . . . . . add 7
The two numbers are {5, 9}
Answer:
![(x+2)^2+(y-4)^2=16](https://tex.z-dn.net/?f=%28x%2B2%29%5E2%2B%28y-4%29%5E2%3D16)
OK, lets start by drawing a basic graph (the first one) so we can visualize.
We already know that the y coordinate of the circle's center is
.
We know that the circle is tangent to the
axis at ![(-2,0)](https://tex.z-dn.net/?f=%28-2%2C0%29)
That means the x coordinate of the center has to be
, as the tangent is a point on the edge of the circle that touches a line at exactly one point.
The radius is the distance from the center of the circle to its edge. We know the center's location now, it is
and a point on the edge of the circle (the tangent point) which is
. so the distance between the points is 4 which is the radius (you can use the distance formula, but it's quite oblivious.)
We can imagine the circle should look like this (the second one):
Now we can piece together an equation
The equation of a circle is
where
is the center and
is the radius. When we put the numbers in: we get
which can be simplified into
which is the answer.
Step-by-step explanation:
He can spend $4.40 on each pet
4.4/22 .
You just have to divide $22 by 5 since Sherman has 5 pets in total
