124 inches of a frame is the required amount. 31 times 4 is 124.

Since it is a square we can use the rules for a 45-45-90 right triangle or Pythagorean Theorem to solve.
Using 45-45-90 rules:
When you cut the square down the diagonal you create a 45-45-90 right triangle with the hypotenuse = 44 in.
The rule is: hyp = sqrt2 * leg
44 = sqrt2 * leg
Divide both sides by the square root of 2 to find the leg.
31 = leg
To find the perimeter of the square, the length needed to make a frame, multiply the length of the leg by 4.
31 * 4 = 124 in

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2 is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes. our only condition is that it passes through the point (-2,5)

A. write an equation of a line that passes through (-2, 5). b. how many different equations could y

answered: Guest

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.
