B. 4.9
C. 7
D. 33.4
F. 13
Answer:
C
Step-by-step explanation:
Hey! So first divide 234 by 18 to find a ratio. You would get 13:1. So apply this to y=91. 91/13 is 7.
To find the value of x when y = 91, set up a proportion using the given values and cross-multiply. Divide both sides of the equation by the coefficient of x to solve for x. The value of x when y = 91 is 7.
To find the value of x when y = 91, we can use the concept of proportionality. We know that when y = 234, x = 18. We can set up a proportion by cross-multiplying:
(x / 18) = (91 / 234)
Cross-multiplying gives us:
234x = 91 * 18
Dividing both sides by 234 gives us the value of x:
x = (91 * 18) / 234
Simplifying the expression, we get:
x = 7
Therefore, the value of x when y = 91 is 7.

Answer:
Likely to get it.
Step-by-step explanation
Do you mean 1% or 1? If 1 then it is likely to pick that.
If it is 1% then it's the opposite (unlikely) to pick that.
Hopes this makes sense!

Answer:
(n ≤ -3) ∪ (-1 ≤ n)
Step-by-step explanation:
I like to "unfold" the absolute value expression by copying the right-side expression to the left side (with the same comparison symbol) and negating its value. I do it this way because I find it easier to work the problem "all at once".
-1 ≥ n +2 ≥ 1
Obviously, -1 ≥ 1 is not true, which means the solution to this inequality will be disjoint sections of the number line. A compound inequality of this nature is generally interpreted to mean the AND of the two inequalities. So, technically, this is an incorrect step. I choose to overlook that, and consider the expression to represent the two inequalities ...
-1 ≥ n +2 . . . OR
n +2 ≥ 1
Subtracting 2 from the above compound inequality gives ...
-3 ≥ n ≥ -1
So, the solution is ...
(n ≤ -3) ∪ (-1 ≤ n)
_____
Further explanation
The inequality symbol negates its content if that content is negative. So, the expression ...
|n+2| ≥ 1
means ...
±(n +2) ≥ 1
This resolves to two cases:
n +2 ≥ 1
and
-(n +2) ≥ 1
The latter case is equivalent to ...
n +2 ≤ -1
which can also be written as ...
-1 ≥ n +2
A more technically correct solution process would identify the two cases and work them separately.

In the graph, the red shading (with the solid edge) shows the solution with respect to the numbers on the x-axis. If you were to graph this on a number line, you would put solid dots at -3 and -1, and shade the line to their left and right, respectively. The blue curve shows the absolute value, and the green line shows y=1, so you can see that the shaded areas correspond to the absolute value being greater than or equal to 1.
The graph of y > 3/4 x – 2 is a dashed line.
The area below the line is shaded.
One solution to the inequality is (0, 0).
The graph intercepts the y-axis at (0, –2).
Answer:
The area below the line is shaded
since it is an inequality with a number of possible solution.
The graph intercepts the y-axis at (0, –2) as seen from the equation above.
