Answer:
-2x-8=10, x=-9
Step-by-step explanation:
After all transactions as wee see nothing's changed but we add '-' to all. And we get -2x-8=10 and -2x=18; x=18/-2=-9
The width can be x.
so it means that the length is 2x
the equation would be
2(x+2x)=24 inches
2x+4x= 24
6x= 24
x=4 (this is the width, so the length will be 8 inches)
the area will be 4 times 8 = 32
Answer:
Step-by-step explanation:
If a given variable varies inversely with another variable, an increase in the value of the given variable would cause a corresponding decrease in the value of the other variable. Also, a decrease in the value of the given variable would cause a corresponding increase in the value of the other variable.
If y varies inversely with x, we would introduce a cost of variation, k so that the expression becomes
y = k/x
When y = 0.25, x = 8
Substituting into the expression above, it becomes
0.25 = k/8
k = 0.25 × 8
k = 2
The inverse variation function is
y = 2/x
A^2+b^2+=C^2 so it would be 9.43 Or C none of the choices are correct
