Answer:
x=20
Step-by-step explanation:
inverse operation
add 7 to both sides
x=20
Answer:
C. (see the attachment)
Step-by-step explanation:
Both inequalities include the "or equal to" case, so both boundary lines will be solid. That excludes choices A and D.
The first inequality is plotted the same way in all graphs, so we must look at the second inequality. The relationship of y and the comparison symbol is ...
-y ≥ (something)
If we multiply by -1, we get ...
y ≤ (something else)
This means the solution space will be <em>on or below (less than or equal to) the boundary line</em>. This is the shaded area in graph C. (Graph B shows shading <em>above</em> the line.)
___
<em>Further comment</em>
Since the boundary for the second inequality is fairly steep, "above" and "below" the line can be difficult to see. Rather, you can consider the relationship of x to the comparison symbol. For the second inequality, that is ...
x ≥ (something)
indicating the solution space is <em>on or to the right of the boundary line</em>.
Answer:
The correct answer is option B. Trapezoid
Step-by-step explanation:
In a trapezoid only one pair of sides area parallel.
a. Rhombus: It have 4 sides opposites sides are parallel and equal.
c. Rectangle :Rectangle have 4 sides opposite sides are equal and parallel. Also all angles are equal.all angles equal to 90°
d. Square : square ave 4 sides all sides are equal and parallel. Also all angles are equal.all angles equal to 90°
