Answer:
B
Step-by-step explanation:
we are given a equation of a line
we want to figure out the equation of the perpendicular line passes through the <u>(</u><u>6</u><u>,</u><u>5</u><u>)</u><u> </u>points
in order to do so
recall that,
we got from our given equation that m=2
because equation of a line is y=mx+b
thus
remember that, when we want to figure out perpendicular line or parallel line we should the formula given by
since we got our perpendicular m is -½, and
, substitute
to get the perpendicular equation you should simplify the above equation to y=mx+b form
distribute -½:
add 5 to both sides:
hence,
our answer choice is B
Answer:
To identify which integer does not belong with the rest, we must first evaluate each.
Step-by-step explanation:
- [25.6...] is already evaluated. Therefore, let's move on to Integer <em>b: </em>
, where is <em>x </em>is 48.
- 48 = 2 * 24--> 2 * 12--> 2 * 6--> 2 * 3
- √48 =
* 2 * 2 * 2 * 3
- We have 1 perfect sqaure:
- When we multiply, we receive 2.
- Therefore, 2 *
- When -51/2 is relatively prime, we receive -25 1/2
- Finally, the last integer is already simplified.
Based on these results, you may determine the number that does not belong with the other three, whether than is through means of irrationability, value, absolte value, or whatever other means you decide.
