Seven because 1+2 is 3 and 3+1 is 4 so in total is seven
Answer:

Step-by-step explanation:
The length of the base is the distance between the points 4+2i and 10+4i, so

The middle point of the base is placed at point

The length of the height is the distance between the points 5+9i and 7+3i

So, the area of the triangle is

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
Answer:
x < 5
Step-by-step explanation:
Hi,
If you have a line under the < or > sign, it means x can be less than OR EQUAL TO, since x has to be less than 5, neither of those signs can work. Now, < means less than and > means greater than. For this, x < 5 is the correct answer because we know that x has to be less than 5.
I hope this helps :)
