Answer:

Graph is option A

Step-by-step explanation:

3x + 5y = –15

To graph the equation , we need to get y alone

$3x + 5y = –15$

Subtract 3x on both sides

$5y = -3x–15$

Divide whole equation by 5

$y=-\frac{3x}{5} -3$

To graph this equation , we need to make a table

Plug in some number for x and find out y

x $y=-\frac{3x}{5} -3$

0 -3

Two points on the graph is (-5,0) and (0,-3)

Graph is option A

Solve for the width in the formula for the area of a triangle

zmey [24]

Answer: $\frac{2A}{h} = w$

Step-by-step explanation:

The formula for area of a triangle is $A = wh\frac{1}{2}$

Now we have to isolate for w.

First multiply by the 2 which is the reciprocal of 1/2 to cancel it out.

$2A = wh\\$

Now divide by h to isolate w.

$\frac{2A}{h} = w$

<span>kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other.

a square does fir this definition since it has 4 equal sides, hence 2 pairs and hte equal sides are adjacent to each other.
so yes a square is a kite

the definition of a rectangle is </span>
<span>a figure with four straight sides and four right angles, </span>

a parallelogram with 4 right angle woudl be a rectangle but any without would not

so it can be, but generally is not
