Answer:
(2, 4)
<u>x = 2</u>
<u>y = 4.</u>
Step-by-step explanation:
To find the solution to the system of equations, we can simply set the two equations equal to each other as shown:
x + 2 = 3x - 2
Subtract 'x' from both sides:
2 = 2x - 2
Add '2' to both sides:
4 = 2x
x = 2.
Plug this value for 'x' into an equation to solve for 'y':
y = (2) + 2
y = 4.
Therefore, the solution to the system is (2, 4).
Answer:
He caught 392 fish last month.
Step-by-step explanation:
If you do how many fish (28) he caught each time multiplied by how many times, you get 14. So do 14x28=392 fish last month.

Answer:
Yes, it's a right-angle triangle
Step-by-step explanation:
3 root 2 is 4.24
3 root 3 is 5.2
3 root 5 is 6.71
3 root 5 is the longest side, so must be the hypotenuse.
a^2 + b^2 = c^2
(3 root 3)^2 + (3 root 2)^2 = c^2
45 = c^2
Square root both sides
C = root 45
( simplified to C= 3 root 5)
Thus, it is a right-angle triangle.
(Root means a square root)
