50 points and will mark brainlest if you were constructing a triangular frame, and you had wood in the length of 4inches, 4 inches, and 7 inches, would it make a triangle? would you be able to create a frame from these pieces of wood? yes or no? = explain your mathematical thinking:

In order for three line segments to form a triangle with non-zero area, they must satisfy the "triangle inequality." There are several ways to express this, but perhaps the simplest is ...

  a + b > c

where a, b, and c are the lengths of sides in order from shortest to longest.

Here, that means the requirement for a triangle is ...

  4 + 4 > 7 . . . .  true, so a triangle can be formed

The triangle inequality is satisfied by these segment lengths.

the answer is (-4,-4)

hope this ! : d

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
