Answer:
17
Step-by-step explanation:
The opposite of a negative number is a positive number!
Therefore, the opposite of -17 is 17 :)
This is a simple ratio. x : y. So x = 21 when y = 5.
21 : 5.
x : 25
So you are timesing each side by 5
So 21 x 5 = 105.
x = 105
Answer:
The answer to this is y=4
Step-by-step explanation:
The answer is the point at which the line intercepts the y-axis.
Hope this helped. :)
A constant of variation is only in the form ay=bx where b/a=constant so given any point y/x=constant let us check here by substituting x=1 and x=2
when x=1---> 2y=14,y=7 here y/x=7
when x=2--->2y=19,y=9.5 here y/x=4.75
so this equation is not constant of variation
let us check an equation of the form 3y=7x
when x=1--->y=7/3--->y/x=7/3
when x=2--->y=14/3---->y/x=7/3
so 3y=7x is a constant of variation
