Answer:
(6, - 2)
Step-by-step explanation:
To determine which point is a solution to the system, substitute the coordinates of the point into the left side of the inequalities and compare the value to the right side
(6, 1)
6 - 1 = 5 < 7
6 + 2 = 8 > 5
(6,1) does not represent a solution
(8, - 1)
8 + 1 = 9 > 7
8 - 2 = 6 > 5
(8, - 1) does not represent a solution
(6, 2)
6 - 2 = 4 < 7
6 + 2 = 8 > 5
(6, 2) does not represent a solution
(6, - 2)
6 + 2 = 8 > 7
6 - 4 = 2 < 5
(6, 2) represents a solution to the system

Answer:
122.5 cm²
Step-by-step explanation:
a = 21cm
b = 14cm
h = 7cm
Area of given figure(trapezium) =
= 21 + 14/ 2 * 7
= 35/2 * 7
= 17.5 * 7
= 122.5 cm²
Math:
Step #1: Distribute
<span><span>(1.8)(1.5x)+<span>(1.8)(−2.6y)</span></span>+(−2.5)(2x)</span>+<span>(−2.5)<span>(1.5y<span>)
</span></span></span>
you'd get: <span><span><span><span>2.7x+ −4.68y </span>+ </span>−5x </span>+ </span>−<span>3.75<span>y
Step #2: Combine like terms
</span></span><span>(<span>2.7x + <span>−5x</span></span>)</span>+<span>(<span><span>−4.68y </span>+ <span>−3.75y</span></span><span>)
</span></span><span>
</span><span>Your answer:
</span><span>−<span>2.3x</span></span>−<span>8.43<span>y</span></span>
