Answer:
No
Step-by-step explanation:
Please write: "Determine whether y+x=1 shows direct variation."
No, it does not, because of the constant term, 1.
If we were to eliminate the 1 and write y + x = 0, then yes, this would represent direct variation.
Answer: 64 cups
Step-by-step explanation:
Each gallon has 16 cups so you multiply 16 by 4 because there are 4 gallons and you get 64. Hope that helped. :)
The first and the 2nd one are correct because x is 21 and y is 49
3 and 4 at wrong
A quarter of an hour is 15 minutes, so a quarter past 7 is 7+15 mins. This gives you:
7:15
Hope this helps and good luck!
The equation y= 2
has one real root and that is x=-1.
What is real roots of the equation?
We are aware that when we resolve a linear or quadratic equation, we always arrive at the value variable of the equation, or, to put it another way, we always locate the equation's solution. This "solution" is what we refer to as the real roots. For instance, when the equation
-7x+12=0 is solved, the actual roots are 3 and 4.
Here given,
=> y = 2
Take y=0 then,
=> 2
=0
=>
=0
=>(x+1)=0
=> x=-1
Hence the given equation has one real root and that is x=-1.
