Answer: 3) k = 22.5; xy = 22.5
Step-by-step explanation:
If two variables are inversely proportional, it means that an increase in the value of one variable would cause a corresponding decrease in the other variable. Also, a decrease in the value of one variable would cause a corresponding increase in the other variable.
Given that y varies directly with x, if we introduce a constant of proportionality, k, the expression becomes
y = k/x
If y = 2.5 when x = 9, then
2.5 = k/9
k = 9 × 2.5 = 22.5
Therefore, an equation for the inverse variation is
y = 22.5/x
xy = 22.5
Answer:
b
Step-by-step explanation:
because heat transfer from hot to cold but it does not transfer to something hotter or the same exact temp
(x+8)(x-6)= 0
x^2-48+8x-6x=0
x^2-48+2x=0
x+8=0 x-6=0
x= -8 x=6
The answer is -8 and 6, I did the process in case you need it
P(G) is 26/52
P(H) is 8/52

<h3>Answer:</h3>
x = -2
<h3>Explanation:</h3>
The line represents the output value (y) for a given input value (x). Where the lines cross, the output values are equal. These lines cross at x=-2.
