ANSWER:
The 1st one: -3x + y = 5
ABOUT STANDARD FORM:
- Ax + By = C
- A & B & C are integers
- A & B are both non - zero
- This form is good to use when wanting to find the x & y intercepts of a line
y - 2 = 3(x + 1) --- IN POINT SLOPE FORM
y - 2 = 3x + 3
+ 2 + 2
y = 3x + 5 --- IN SLOPE INTERCEPT FORM
-3x -3x
-3x + y = 5 --- STANDARD FORM
Hope this helps you!!! :)
Answer:
78 trees
Step-by-step explanation:
No. of trees planted = Area of square
No. of trees planted = 6084
Row = side of square
Side = √(Area)
Side = √(6084)
Side = 78 trees

Answer:
y = (x -1)² -16
Step-by-step explanation:
Note the location of the vertex (point A) on the graph. Its x-coordinate is readily identifiable as 1. Its y-coordinate is some value between -15 and -20, closer to -15. (If you go to the trouble of finding the vertex coordinates, you discover they are (1, -16).)
Once you have determined what the vertex is, you can compare the offered answer choices to the vertex form ...
y = (x -h)² +k
where (h, k) are the vertex coordinates. That is, you are looking for an answer choice that is something like ...
y = (x -1)² -16
This question is solved applying the formula of the area of the rectangle, and finding it's width. To do this, we solve a quadratic equation, and we get that the cardboard has a width of 1.5 feet.
Area of a rectangle:
The area of rectangle of length l and width w is given by:

w(2w + 3) = 9
From this, we get that:

Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots
such that
, given by the following formulas:
In this question:


Thus a quadratic equation with 
Then


Width is a positive measure, thus, the width of the cardboard is of 1.5 feet.
