5)Substituting any of the following equations; i chose bottom into top:
-2x+5=x+2
=>-3x=-3
=>x=1
Sub the x in any of the eqs to find y so
Y=1+2
=>Y=3
ANS: (1,3)
6) substituting the top equation into the bottom one:
3x+2x+4=9
=>5x=13
=>x=13/5 or 2.6
Sub the x in any of the eqs to find the y so
Y=5.2+4
=>y=9.2
ANS: (2.6, 9.2)
Answer:
The points corresponding to P=(3,4) and Q=(6,7), so the answer is D.
Step-by-step explanation:
Ok, in mathematics, given two sets X and Y, the collection of all the ordered pairs (X, Y), formed with a first element in X and a second element in Y, is called the Cartesian product of X and Y. The Cartesian product of sets allows define relationships and functions. In this case, it is a function that contains two points, denoted P and Q. Given, the ordered pair of each, first read the one corresponding to the X axis and then to the Y axis.
For P: you read X and you see that it is on 3 (between 2 and 4), and then the Y axis is on 4 (between 3 and 5).
For Q: you read X and you see that it is on 6 (between 5 and 7) and then the Y axis is on 7 (between 6 and 8)
The answer is 2.686, and i am writing these extra characters to pass the 20 character qualifications.
The answer is 540 because 32/48 is 2/3 and 360/540 equals 2/3
A.
This is because in each circle the lines increase by one, so from the triangle (3 lines) to the rectangle (4 lines) it only makes sense to put a pentagon (5 lines)
