Answer: The answer would be the first choice.
Step-by-step explanation:
Remember that a function is where every INPUT has exactly ONE OUTPUT. That means for the coordinates (x, y), no pair could have an x value repeat. So, the first ordered row pair does not have any repeating x values, so it's the first answer.
15 minutes = 1/4 of an hour = 0.25
64 x 4.25 =272 miles total
Answer:
Step-by-step explanation:
for this equation
d=st
we can represent s as d/t
we can represent t as d/s
and in real world we have a lot of this type of equations
some of them are,
d=m/v ( density = mass / volume )
C = m.c ( heat capacity = mass x specific heat )
Here's how you solve this. So, x+y=2, right? Let's isolate x. x+y-y=2-y. x=2-y. NOW, if x=2-y, in 3x+2y=5, we can REPLACE x with 2-y and use it to solve for y! 3x+2y=5. 3(2-y)+2y=5. (3*2)+(3*-y)+2y=5. 6+(-3y)+2y=5. 6+(-y)=5. 6+(-y)-6=5-6. -y=-1. -y/-1=-1/-1. y=1.
So, if y=1, we can substitute that back into either equation--but let's go with the easier one, x+y=2. x+1=2. x+1-1=2-1. x=1. 1+1=2, so that works; let's check the other equation. 3(1)+2(1)=5. 3+2=5. 5=5. That's correct!
Answer: x=1, y=1
