Answer:
Step-by-step explanation:
y = |x - 3| + 1
to translate up one unit becomes
y = |x - 3| + 1 + 1
or
y = |x - 3| + 2
which could be rewritten
y = |x - 1|
to translate down one unit
y = |x - 3| + 1 - 1
y = |x - 3|
The answer is B. It's B because a straight line has a degree of 180, if you have 2, then of course it becomes 360. In B, you have 90, 90, and 150. If one of the angles is 30, you add that onto 150 to get 180 and add 90 and 90 together to get 180. Naturally, add those two answers together to get 360.
If the line is moving about 4 feet every 15 minutes, then a person will need about 3 hours to reach 50-foot line from the back to the front. It's because:
50 / 4 = 12,5 (that's how many quarters of an hour one needs to move 50 feet)
12,5 * 15 = 187,5 (that's how long it will take in minutes)
187,5 min = 3h 7min 30 sec
Approx. - 3h
1. D; -5m+2m, because -5+2=-3
2. B; 4 terms, every part of an expression that's not the subtraction/addition sign counts as a term.
3. Not 100% sure about this one, but I'll go with B; 4x².
4. C; 5b, that term cannot be combined because the variable is different from the rest.
I hope this was helpful.
¹/₄x - 3 ≥ 2
+ 3 + 3
4(¹/₄x) ≥ 4(5)
x ≥ 20
