Let's assume
that number is x
now, we are given
The difference between nine times a number an 7 is -70
nine times of that number is 9x
so, we can set up equation
now, we can solve for x
so, number is -7.........Answer
Answer:
The standard from of the expression is:
Step-by-step explanation:
Here the given expression is :
Now, the standard form of a circle is given as :
Here, (h,k) = Coordinates of Center, r = Radius
Also, use the algebraic identity:
Now, converting the given expression in the standard form, we get:
Add 2 on both sides of the equation, we get:
So, here the standard from of the expression is:
Center coordinates here are (h,k) = ( -1 ,1) and Radius = 2 units
