Answer:
(1,2) is a solution to both equations
Step-by-step explanation:
To determine if (1,2) is a solution to both equations, substitute into the equation and see if it is true
2x+y =4
2(1) + 2 =4
2+2 =4
4=4
true
y =3x-1
2 = 3(1) -1
2 =3-1
2=2
true
Since both statements are true
(1,2) is a solution to both equations
Lcm is 24 and the gcf is 2
Do you want the answer for question 1!? It's already done! It says Given right there, that's an example answer :)
First we see there are two extremes, two limits
-2 and 5
x is between them
BUT theres a difference , the point at left is black
the point at right is white rounded
this means x is equal or less than -2
and x is ONLY less than 5 , not equal
so this means the answer is the d option
