2x+5y=21, x+y=3
y=3-x
2x+5y=21
2x+5(3-x) =21
2x+15-5x=21
2x-5x+15=21
-3x+15=21
-3x=21-15
-x=6/3
-x=2
x=-2
Answer:
Quadrant II
Step-by-step explanation:
Since there are 360 degrees in a circle we will subtract it from 860 until we get a number less than 360

Since it less than 180 but more than 90 it will be in the second quadrant
Hope this helps! <3
All we have to do is multiply by two
4 3/4 * 2 = 9 1/2
1/2 * 2 = 1
2 1/2 * 2 = 5
Answer: B. No
Step-by-step explanation:
Direct variation has the following form:

Where the constant of variation is "k".
By definition, in direct variation, when the variable "x" changes, tha variable "y" changes in proportion to the variable "x".
As you can observe in the table, when the value of the variable "x" increase, the values of the variable "y" decrease, therefore we can conclude that it is not a direct variation.
Then the answer is the option B.
