Answer:
B)
Step-by-step explanation:
because 45= 1(45)
the rest don't show it on the table
Answer:
Step-by-step explanation:
slope=m= 5
points=(-1,2)
<u>By point-slope form:</u>
-
=m(
)
<u>Substitute the values in formula:</u>
<u>y-2=5(x+1)</u> (It is the point slope form)
Now,
<u>Slope intercept form:</u>
y-2=5x+5
y=5x+5+2
<u>y=5x+7</u>
<u />
<h3><u>If you need to ask any questions, please let me know.</u></h3>
You can work it out by using trial and error
so you get
x=3 , y=2

![\Large\boxed{\mathsf{\Rightarrow NO\quad SOLUTIONS}}](https://tex.z-dn.net/?f=%5CLarge%5Cboxed%7B%5Cmathsf%7B%5CRightarrow%20NO%5Cquad%20SOLUTIONS%7D%7D)
Step-by-step explanation:
<h3><u>TO SOLVE:</u></h3>
Isolate by the x on one side of the equation.
<h3><u>SOLUTIONS:</u></h3>
First, subtract 3x from both sides.
![\displaystyle \Rightarrow \mathsf{3x+11-3x=3x-11-3x}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5CRightarrow%20%5Cmathsf%7B3x%2B11-3x%3D3x-11-3x%7D%7D)
Solve.
![\displaystyle \mathsf{11=-11}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cmathsf%7B11%3D-11%7D)
Sides are NOT equal.
![\Large\boxed{\mathsf{\Rightarrow THERE \quad ARE \quad NO \quad SOLUTIONS}}}](https://tex.z-dn.net/?f=%5CLarge%5Cboxed%7B%5Cmathsf%7B%5CRightarrow%20THERE%20%5Cquad%20ARE%20%5Cquad%20NO%20%5Cquad%20SOLUTIONS%7D%7D%7D)
Therefore, there are no solutions.
Let x = Barbie's number
1/3 x -20 = 72
1/3 x = 92
x = 92*3=276
