Answer:
7
Step-by-step explanation:
(5x6) equals 30, then 5+4-3 equals 6. So divide 30 and 6 and you'll get... actually this is starting to confuse me.
Answer:
(x,y)=(5,6)

Answer:
Step-by-step explanation:
<u>Use properties of rhombus:</u>
- diagonals are perpendicular
- diagonals are angle bisectors
- opposite angles are equal
<u>The angle measures are:</u>
- m∠2 = 90°
- m∠3 = 70°
- m∠1 = m∠4 = 90° - 70° = 20°
The solution of a linear inequality in two variables like Ax + By > C is an ordered pair (x, y) that produces a true statement when the values of x and y are substituted into the inequality.
Example
Is (1, 2) a solution to the inequality
2x+3y>1
2⋅1+3⋅2>?1
2+5>?1
7>1
The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥. The half-plane that is a solution to the inequality is usually shaded.
Example
Graph the inequality
y≥−x+1
