A 4-column table with 4 rows. Column 1 is labeled x. Column 2 is labeled y. Column 3 is labeled x + y = 56. Column 4 is labeled 2 x minus 7 = y. All rows are blank. Using the guess and check technique, find two numbers that satisfy both conditions. The sum of the two numbers is 56. The second number is seven less than two times the first number. What is the value of the first number, x? 19 21 31 35

Step-by-step explanation:

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

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.
