Step-by-step explanation:
If a triangle is rotated 90° about the origin.
The rule that describes the transformation is
(x, y) → (–y, x)
Answer:
well you should firstcalculate the distance then divide by the primary source and you should be able to get the answer after substituting

Write an equation in point-slope form for the line that has a slope of
and contains the point (2, -9).



Where
y₁ = the y-coordinate of the point that the line contains
m = slope
x₁ = the x-coordinate of the point that the line contains
Provided Information:-
y₁ = -9
m = 
x₁ = 2
Substitute the values:-

On simplification,

According to the answer and explanation, we conclude that
[<u>The correct answer is Option B]</u>

Given:
Height of Isabelle = 62 inches
Shadow of Isabelle = 93 inches
Shadow of tree = 279 inches
To find:
The height of the tree.
Solution:
Let height of tree be x.
Ratio of height to shadow for Isabelle and tree are


The shadow of Isabelle and tree are proportional to their shadows. So, both ratios must be equal.

Multiply both sides by 279.



Therefore, the height of tree is 186 inches.

Answer: 13</h3>
=========================================================
Explanation:
We're told that there are 50 people in each grade that are surveyed. So that means 50 eighth graders were surveyed.
Add up the values along the bottom row. Set the sum equal to 50 and solve for m
m+8+29 = 50
m+37 = 50
m = 50-37
m = 13
Then note how 13+8+29 = 50 along the bottom row. Also, for the top row we have 17+15+18 = 50 as well.
