Answer:
Both 
and 
are solutions to the system.
Step-by-step explanation:
In order to determine whether the two given points represent solutions to our system of equations, we must "plug" thos points into both equations and check that the equality remains valid.
Step 1: Plug into 
The solution verifies the equation.
Step 2: Plug into 
The solution verifies both equations. Therefore, is a solution to this system.
Now we must check if the second point is also valid.
Step 3: Plug into
Step 4: Plug into
The solution verifies both equations. Therefore, is another solution to this system.
Answer:
5y+5
Step-by-step explanation:
I hope this is right
F(2)= 4(2)-1
8-1
f(2)= 7
g(2)= 2(2)+2
4+2
g(2)= 6
Ratio of the sides of the triangles,
<em>2 : 3 : 4 </em>
Let's consider each side to be
2x,3x and 4x
Therefore the perimeter of the triangle is,
<em>2x + 3x + 4 x = 9x </em>
The shortest side is 15 inches.
We know that the smallest value in the above ratio is 2
Therefore,
2x = 15 inches
x = 7.5 inches
<u>☞</u><u>Perimeter of the triangle </u>
= 9x
= 9 * 7.5 inches
= <u>67.5 inches</u>
