5h - 3 = 17
First, substitute h for 4 and the equation becomes 5(4)-3
Then, use PEMDAS (order of operations) to answer.
5 x 4 = 20
20 - 3 = 17
Since x and y are directly related, the equation for their comparison will look like
kx = y
where k is your constant. They give you an instance in the problem where x = 27 and y = 81. Plug this into the above equation and solve for k.
kx = y
k (27) = 81
k = 3
Thus, the constant of variation is 3.
For the first question: The equation would be set up as 30=1/2(12x) Then solve for x. (Or just plug that formula into Desmos)
Answer: x=5
Answer:
h−1(x)=−5x/3+5/6
Step-by-step explanation:
your answer is the second one
Answer:
Step-by-step explanation:
Open the brackets first:
Simplify:
It is determined that this can't be factored, so rewrite the equation so you can complete the square.
Take the square of 1.5 and add it to both sides:
Factor:
