The answer is 54. Let me know if you need an explanation
Answer:
Step-by-step explanation:
The total angle measure of supplementary angles (straight angles like this one) will always equal °, so the following equation can be used:
Because the expressions x and y² varies inversely, the equation that can be used in order to relate them is,
y² = k/x
k here is the constant of proportionality. Using the first set of given, x = 4 and y = 10, we determine the value of the proportionality constant.
k = (x)(y²)
Substitute the known values to the equation,
k = (4)(10²) = 400
The completed equation for the relation is therefore,
y² = 400/x
Substituting the value of y to this equation,
(2²) = 400/x
The value of x is 100.
<em>ANSWER: D. x = 100</em>
12
Step by step:
14 1/2=14.5
1 1/4=1.25
14.5 divided by 1.25=11.6
Answer:
D. (-∞,4]
Step-by-step explanation:
The range is the y values
The lowest y values is negative infinity
The highest y values is 4
( - inf, 4]
We use the parentheses since we cannot get to negative infinity, the bracket since we reach 4
