Answer:
C. y = 1/4x + 1/4
Step-by-step explanation:
Just did it on Edmentum and got it right
A certain journey by train takes 5 hours at the speed of 45 km/h. What will be the speed of the train to complete the same journey in 3 hours?
-1
In a slope intercept equation, y=mx+b B is always the Y intercept
The statement " <span>y </span><span>varies directly as </span><span>x </span><span>," means that then </span><span>x </span>increases,<span>y </span><span>increases </span><span>by the same factor so we have: y/x=k
for question 1 then: 15/5=3
so the direct variation equation is y=3x
Now if x=9 you only have to replace x in your equation and you get:
y=3*9=27</span>
Answer:
Step-by-step explanation:
The given expression is:
Moving the expression to the other side in the fraction changes its sign to opposite. A numerator with negative exponent, when written in denominator will have the positive exponent. Using this rule, we can write:
The exponent 5 can be distributed to both numerator and denominator as shown:
The power of a power can be written as a product. i.e.
So, the expression similar to the given expression and with positive exponents is:
