Step-by-step explanation:
Water is the universal solvent" with a grain of salt (pun intended). Of course it cannot dissolve everything, but it does dissolve more substances than any other liquid, so the term fits pretty well. Water's solvent properties affect all life on Earth, so water is universally important to all of us.
For finding the value of b, we must consider that Line MN passes through points M(4, 3) and N(7, 12). With this condition y = mx + b, can be written 3=4m+ b (because line passes through M(4,3) ) and 12=7m+b, b ( because line passes through M(7,12)).
We have a system of equation
4m+ b=3
7m+b=12
For solving this, 4m+b- (7m+b)= 3-12, it is equivalent to -3m= -9 and then m=3, if m=3 so
4x3 +b =3 implies b= 3 -12= -9, so the value of b= -9

Let the value of the number be represented as x.
Then, write out an equation;
3x=2x+3 <--- Solve for x now
3x-2x=3
x=3
Therefore the number is 3.
Hope I helped :)

Answers: Angle 4 and angle 2</h3>
==================================================
Explanation:
Supplementary angles add to 180 degrees. Visually, supplementary angles can be glued together to form a straight angle or a straight line.
We see that happens with angles 1 and 4, and this also happens with angles 1 and 2. This is why these two angles make up the answer.
--------------
The other answer choices can be ruled out.
Angles 1 and 9 would be congruent if we knew the shallow sloping lines were parallel. The only time angles 1 and 9 are supplementary is if both are 90 degrees. In any other case, they are not supplementary angles.
Angles 1 and 12 are same side exterior angles. They would be supplementary if the shallow sloping lines were parallel. However, if you extend out each line, you'll see that they eventually intersect. Parallel lines never intersect.
