Answer:
Step-by-step explanation:
<u>The line x = 3 is parallel to y- axis, the perpendicular line is going to be parallel to x- axis and will have an equation:</u>
<u>Since it passes through the point (-2, 5), it will have a = 5:</u>
- y = 5 is the line we need
Answer:
Step-by-step explanation:
Since, the variables x and y are inversely proportional.
Answer:
7.5 or 15/2
Step-by-step explanation:
x-3x+6=2x-24 -- Combine like terms
-2x+6=2x-24 -- Add 2x to each side
6 = 4x-24 -- add 24 to each side
30 = 4x -- divide by 4
15/2 or 7.5 = x
- Subtraction can be thought of as the inverse operation of addition, OR as addition itself, if you look at it as adding a negative number.
- The number line allows us to interpret subtraction (or addition of a negative) geometrically; we can view it as a movement to the left on the number line with a distance equal to the number being subtracted.
- Lastly, the value of any expression a - b (where a and b are real numbers) is determined by the relative sizes of the numbers. If a > b, then a - b > 0 (a positive result). If b > a, then a - b < 0 (a negative result.
