Answer:
Its -2
Step-by-step explanation:
Let's solve your equation step-by-step.
−12−4x+3=−1
Step 1: Simplify both sides of the equation.
−12−4x+3=−1
−12+−4x+3=−1
(−4x)+(−12+3)=−1(Combine Like Terms)
−4x+−9=−1
−4x−9=−1
Step 2: Add 9 to both sides.
−4x−9+9=−1+9
−4x=8
Step 3: Divide both sides by -4.
−4x
−4
=
8
−4
x=−2
If you can rewrite the formula as (x-a)² + (y-b)² = r², the center is at (a,b) and the radius is r.
If you work out this equation, and map it to the original, you will find that the +4x term hints that a = 2 (double product) and -12y hints that b=-6, and r=6.
So, the formula can be written as (x+2)² + (y-6)² = 6² and the center is at (-2,6) and the radius is 6.
Answer:
<h3> The first: The easiest to solve for is x in the first equation.</h3>
Step-by-step explanation:
To get x from first equation you just need to subtract 4y from both sides.
The rest of variables needs two operations to get variable - subtracting and then dividing.
Area = lw
So 7(4) =28
Area = 28
The answer is C.
