The expression <span>4(2x – 3) – 4x is equal to 4·2x-4·3-4x=8x-12-4x=(8x-4x)-12=4x-12.
</span>
1. 4x-12=4x-12, then 0=0. This equation has infinite amount of solutions;
2. 4x-12=3x-4,4x-3x=-4+12,x=8. This equation has one solution.
3. 4x-12=3(2x-6),4x-12=6x-18,4x-6x=-18+12,-2x=-6,x=3. This equation also has one solution.
4. 4x-12=4(x-5),4x-12=4x-20,4x-4x=-20+12,0=-8 is not right equality, then this equation hasn't solutions.
Answer: Correct choices are B and C.

Answer:
A. -50 feet
Step-by-step explanation:
To find the number closest to sea level, take the absolute value of each number and see which is closest to zero.
A. -50 feet abs (-50) = 50
B. -68 feet abs (-68) = 68
C. -77 feet abs (-77) = 77
D. -86 feet abs ( -86) = 86
E. -97 feet abs (-97) = 97
The smallest number is 50. -50 ft is closest to sea level
Answer:
They represent the rise and run of the graph.
Step-by-step explanation:
The difference between the x-axis of the points represents the "run" of the graph (or how much you should run along x-axis to get to the next point.)
The difference between the y-axis of of the points represents the "rise" of the graph (or how much you should rise up the y-xis to get to the next point).
The ratio of rise to run is the slope of the graph, which tells us how many steps should we take on the y-axis for every step we move forward on the x-axis.
The answer is 3 hope this helps pls thank me
