Abbi can substitute y=3 and x=3 into the equation y=1/3x+2 and show that a true statement results thus option (A) will be correct.
<h3>What are the roots of an equation?</h3>
The roots of an equation are the solution of that equation, since an equation consists of hidden values of the variable so to determine them by different processes and then the resultant is called roots.
As per the given equation,
y = 1/3 x + 2
If (3,3) lies on the equation then it must satisfy.
3 = (1/3)3 + 2
3 = 1 + 2 = 3
Thus, Abbi can substitute into the equation to prove.
Hence "Abbi can substitute y=3 and x=3 into the equation y=1/3x+2 and show that a true statement".

Plug in the first equation into the he second equation
3x-(2x+7)=-9
3x-2x-7=-9
x-7=-9
x=-2
plug in x=-2 into the first equation
y=2(-2)+7
y=-4+7
y=3
answer: (-2,3)
Answer:
2005 points
Step-by-step explanation:
1. 35x50=750
2. 2 min. 45 sec.=(-165 sec.)
3. 500x5=2500
4. 2500-495=2005
Hope this helped!!:)
Y = kx
9 = k4
k = (9/4)
y = (9/4)x
when x=10,
y = (9/4)10
y = 22.5
Firstly lets find how many breaths in one minute.
Since one minute equals 60 seconds we need to multiply 4 and 60
4x60=240
Lillian takes 240 breathes in one minute; but since we need to know how many breaths in TWO minutes, we multiply 240 and 2.
240x2=480
So Lillian takes 480 breaths in two minutes.
