Answer:
the first option (2x+3y=-6)
Step-by-step explanation:
I think C would be for number 11
A is for 12.
x/2 < - 18
Answer:
5x3=15
Step-by-step explanation:
Answer:
The other endpoint is located at (-4,-2)
Step-by-step explanation:
we know that
The diagonals of a rhombus bisect each other
That means-----> The diagonals of a rhombus intersect at the midpoint of each diagonal
so
The point (0,4) is the midpoint of the two diagonals
The formula to calculate the midpoint between two points is equal to
we have
substitute
<em>Find the x-coordinate 
of the other endpoint</em>
<em>Find the y-coordinate 
of the other endpoint</em>
therefore
The other endpoint is located at (-4,-2)
Answer:
c > 5
Step-by-step explanation:
The properties of equality can be used to solve inequalities. Attention needs to be paid to ordering.
<h3>Application</h3>
We can subtract 3 from both sides to solve this.
c +3 > 8 . . . . . . given
c +3 -3 > 8 -3 . . . . subtract 3 from both sides
c > 5 . . . . . . . . . simplify
The solution is c > 5.

<em>Additional comment</em>
Adding or subtracting a value to a number on a number line is equivalent to shifting it right or left. It does not change ordering.
Multiplying or dividing by a <em>positive</em> number is equivalent to expanding or compressing the distance from zero. It does not change ordering.
Multiplying or dividing by a <em>negative</em> number reflects the value across the origin, in addition to expanding or compressing the distance from zero. This reflection reverses the left-right ordering. For example, -2 < -1, but 2 > 1. (Both numbers multiplied by -1.)
As long as you're aware of the effect on ordering, you can use any of the properties of equality to solve inequalities.
