Answer:
and 
Step-by-step explanation:
We know,
'Direct Variation function' is the function where two quantities vary directly i.e. variables x and y are said to be directly varying if 'y=kx' where k is the constant of variation.
Thus, from the options, we see that the function,
is varying directly with the constant of variation i.e. k = 1.
is also varying directly with constant 
Answer:
Step-by-step explanation:
We want to find the square root of 50;
We need to first rewrite 50 as a prime factorization.
We now split the square root to get:
Take square root to get:
To the nearest tenth we have
No because equivalent is like 5/10 so it's not right
Answer:
y= 13/2x +12
Step-by-step explanation:
so first move expression to right hand side
13x-2y+24=0
2y= 13x+24
then divide every term by 2 to cancel out 2
2y/2 = 13x/2 + 24/2
and then you get your final answer
