Answer:
45
Step-by-step explanation:
In an inverse variation situation, we have mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant.
So in this case: x*y is a constant
since x=9 and y=5 so
xy = 45
the constant of variation is 45
For inverse function, we usually write it as 
EXPLANATION:
3x= 2x+16
=> 3x-2x=16
=> x=16°
m∠1= 360 - (16+16)
= 360 - 32
= 328°
ANSWER:
x = 16°
m∠1 = 328°
Hope it helps u!
Answer:
x ≠ - 2, 5
Step-by-step explanation:
The restrictions occur in the denominator which cannot be zero as this would make the function undefined. Equating the denominator to zero and solving gives the values that x cannot be.
solve x² - 3x - 10 = 0 ⇒ (x - 5(x + 2) = 0 ⇒ x = -2, 5
Answer:
x > 3
Step-by-step explanation:
This is based on the concept 'when a negative number is multiplied to both sides of the inequality, the sign gets reversed. For example, x > - 2 when it is multiplied by - 1, it becomes - x < 2.'
*only when the number is -ve.
Similarly, in this question, multiply both sides by - 1.
2x > 6
x > 6/2
x > 3
For more : take - 5 > - 2, as you know
Note that 5 is actually greater than 2. To make this true we change signs
Answer:$13.82
Step-by-step explanation:
$79.99+7.75%=$86.18
