Answer:
Step-by-step explanation:
The key to answering this is to know that the only time you'll change the direction of the sign is when you multiply or divide by a negative number.
-46 - 8x > 22
-8x > 22 + 46
-8x > 68
x < 68/-8 (we divided by -8 so the inequality changed direction)
x < -17/2
Answer:
10
Step-by-step explanation:
1 2 3 4 5
1 shakes hands with 2,3,4,5
2 shakes hands with 3,4,5 but not with 1 because they already shook hands once
similarly, 3 only shakes hands with 4 and 5, same reason as abov
4 with 5 only, same reason
Perimeter = 2 widths + 2 length
356 = 2(84) + 2 length
356 = 168 + 2 length
356-168 = 2 length
188 = 2 length
so length = 188/2 = 94 yards
Answer:
Step-by-step explanation:
use the formula { a couple of times} cos 2 Θ = 2 cos ² Θ - 1 = 1 - 2 sin ² Θ....your answer will likely have a cos 2x , a cos 4x , and a cos 6x in it.....note : cos ² Θ - sin ²Φ = cos ( Θ + Φ) cos (Θ - Φ) will also be needed for appropriate choices of Θ & Φ in terms of x
The relation t relates x to y. To determine if it is a function, see if one x value can give two different y values. Since each x value only has one y value, the relation is a function. To check if the inverse is a function, see if any one y value will give multiple x values. By inversing t, there are two values of x for the value of y = -4 (x = 4 and x = 6), so this is NOT a function.
Answer: Relation t is a function. The inverse of relation t is NOT a function.
