First you put the equation in point slope form- Y-0= 5x - 4
Then add the zero to the 4.
Final answer: y= 5x -4
The answer is B. 0.25 inch. Lets multiply all of them by the same factor. Since A. and B. have 3 decimals, lets divide all numbers by 1000: A. 0.026 * 1000 = 26, B. 0.25 * 1000 = 250, C. 0.24 * 1000 = 240, D. 0.025 * 1000 = 25. So, by comparing the whole numbers, it can be concluded that the biggest steel rod is B. 0.25 inch.
It's not too difficult!! your absolute value expression is already isolated, so now you have to set it up like this:
5v + 3 > -9
and
5v + 3 < 9 (opposite of original, flip inequality symbol)
this is because absolute value only tells you how many units away a number/expression is from 0 on a number line. it could go to the left, or the right--negative, or positive. so you have to allow for both equations
from there, just solve them like normal inequalities
5v + 3 > -9 ... subtract 3
5v > -12 ... divide by 5
v > - 12/5
5v + 3 < 9 ... subtract 3
5v < 6 ... divide by 5
v < 6/5
so, v must be greater than -12/5, and less than 6/5
