Answer:
x=−2y+6
Step-by-step explanation:
Step 1: Add -12 to both sides.
−2x+12+−12=4y+−12
−2x=4y−12
Step 2: Divide both sides by -2.
−2x /−2 = 4y−12/−2
x=−2y+6
You're trying to find constants

such that

. Equivalently, you're looking for the least-square solution to the following matrix equation.

To solve

, multiply both sides by the transpose of

, which introduces an invertible square matrix on the LHS.

Computing this, you'd find that

which means the first choice is correct.
Answer: B. 0 ≤ x ≤ 4

Answer:
C. The circumference of circle 1 is less than the circumference of circle 2.
Step-by-step explanation:
6<7
We know that the formula for the area of a circle is πr². This means the greater the radius, the greater the area.
We also know that the formula for circumference is 2πr. It is also dependent on radius. The greater the radius, the greater the circumference.
Given that Circle 2 has a greater area, this means that it has a greater radius which in turn means that it has a greater circumference.
C. The circumference of circle 1 is less than the circumference of circle 2.
