Given:
To find:
The quadrant in which lie.
Solution:
Quadrant concept:
In Quadrant I, all trigonometric ratios are positive.
In Quadrant II, only and
are positive.
In Quadrant III, only and
are positive.
In Quadrant IV, only and
are positive.
We have,
Here, is negative and
is also negative. It is possible, if
lies in the Quadrant IV.
Therefore, the correct option is D.
Answer:
The y-coordinate would be 17.5
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
y ----->material needed in yards
x ----> number of curtains
we know that
For y=5, x=2
Find the value of the constant of proportionality k
substitute the given values of x and y
The linear equation is equal to
If the x-coordinate was 7
then
substitute in the equation x=7 and solve for y
therefore
The y-coordinate would be 17.5
