Answer:
The constant of variation is 3
Step-by-step explanation:
Given.
And y is directly related to x
∝ 
Here k is constant of variation
--------------(1)
Put the and value in equation 1.
So, the constant of variation is 3.
Answer:
(3, 5)
Step-by-step explanation:
The graph is is the standard y=|x| except the values tells you that x shifts 3 (within the absolute value or parentheses x does the opposite) to the right and the y value shifts 5 up (numbers outside parentheses affects y and does what it says). You can try using a table of values then graphing to check your answer.
Domain is the set of numbers you can use
usually, domain=all real numbers except those that divide by zero
so find those exceptions
find what numbers make deonenator equal to 0 and exclude them
x-23 is denom
x-23=0
x=23
doman is all real numbers except 23
Answer:
15 is 30% of 50
Step-by-step explanation:
We have, 30% × x = 15
Multiplying both sides by 100 and dividing both sides by 30,
we have x = 15 × 100/30
x = 50
If you are using a calculator, simply enter 15×100÷30, which will give you the answer.
Answer:
Step-by-step explanation:
x²-12x+(-12/2)²=x²-12x+36=(x-6)²
