Answer:
A. (1, -2)
B. the lines intersect at the solution point: (1, -2).
Step-by-step explanation:
A. The equations can be solve by substitution by using the y-expression provided by one of them to substitute for y in the other.
This gives ...
3x -5 = 6x -8
Adding 8-3x to both sides, we get ...
3 = 3x
Dividing both sides by 3 gives ...
1 = x
Substituting this value into the first equation, we can find y:
y = 3(1) -5 = -2
The solution is (x, y) = (1, -2).
__
B. The lines intersect at the solution point, the point that satisfies both equations simultaneously. That point is (1, -2).
Answer:
When you fill in the blanks you get ($0.25*x)+(0.1*y)+(0.05*z). When you evaluate it you get $1.35, which is the total amount of change in her pocket.
Step-by-step explanation:
All of the numbers that are given in the equation are values of the coins (ex: a quarter is worth $0.25) and the variables are the different coins. Multiply the quantity of each coin (that's the variable) by its value then add them together. Finally, plug in the numbers it gives you for x, y, and z.

Answer to this question depends on the person answering the question.
Step-by-step explanation:
The set of statements that Neil made he might have tried to indicate that mathematics is no less than reading itself. Math is a beautiful language and he is trying to advocate that like people compel on reading, people should also compel learning mathematics up to a certain extent. People should try to discover the beauty of mathematics.
When people in general say that they are bad at mathematics they might mean they are not good at basic math or they might also mean that they are not good in advance mathematics. Since the field of advance mathematics or applied mathematics does not come in to play in the common life therefore, people in general think that is it okay to say that they are bad at math.
For an instance advance math which is behind the design of jet engine, plane engine, math behind the architecture of a building is hidden from the vision of common people and neither they are interested. So I believe for them it is okay to say that they are bad at math.
But if one is curious to learn and apply mathematics, then it certainly is not okay to say that he/she is bad at math.
