Answer:

use a calculater multiply them

2 over 9 would just be 9 x 9= 81

4 over 2 would just be 2 x 2 x 2 x 2 = 16

do NOT do 2 x 4 bec that will be 8

Right triangle ABC is on a coordinate plane. Segment AB is on the line y=2 and is 6 units long. Point C is on the line x=-3. Wha

The y-coordinate of point C may have a value of 5 or -1.

<h3>What is a right-angle triangle?</h3>

If any of its inner angles is 90 degrees, the triangle is said to be right-angled. Another term for this triangle is the right triangle or 90-degree triangle.

The given data in the problem is;

A coordinate plane contains the right triangle ABC.

AB = 6 units

Surface area, A= 9 square units

The AB symbol is located on the x-axis parallel line y=2.AB will thus be perpendicular to the x-axis.

As a result, AB will be parallel to the side that contains point C. (BC or AC). As a result, the triangle's area should be justified by the length of the side or leg containing point C, which is the point's y-coordinate.

The other triangle leg's length should be,

BC = AC = 9/3

BC = AC = 3

Therefore, the point C's y-coordinate can be,

2±3 = 5,-1

Hence, the y-coordinate of point C may have a value of 5 or -1.

Select the correct answer.

Yuliya22 [10]

Answer: B is your correct answer.

Step-by-step explanation: If she has already made $95.00 from selling jam and made $24.00 from demonstrations you add those together to get $119. Then you subtract $119.00 from $450.00 and you'll have $331.00 left to make. Finally you divide $331.00 by $5.00 (cost of jam) and you'll find that you have to sell 66 more jars of jam.

-3

Step-by-step explanation:

The <em>change in y</em> is the difference in y-coordinates between the lower right point and the upper left point. Similarly, the <em>change in x</em> is the difference in the x-coordinates of those points.

$\text{Slope}=\dfrac{\text{change in y}}{\text{change in x}}=\dfrac{\boxed{3}-6}{2-\boxed{1}}\\\\=\dfrac{\boxed{-3}}{\boxed{1}}\\\\\\=\boxed{-3}$
