Answer:
Step-by-step explanation:
The detailed step by step calculation using the probability density function approach is as shown in the attached file.
1. Commutative property of multiplication
IM SO SORRY IF IM WRONG
Answer:No
Step-by-step explanation:
Given system of equation is:
2x + 3 = y
2x + y = 15
To check whether (2,7) is solution to this system or not, we will put x=2 and y=7 in both equations.
Putting x=2 and y=7 in Eqn 1
2(2) + 3 = 7
4 + 3 = 7
7 = 7
Thus the ordered pair satisfies the equation
Putting x=2 and y=7 in Eqn 2
2(2) + 7 = 15
4 + 7 = 15
11 ≠ 15
The ordered pair do not satisfy the second equation.
Hence,
(2,7) is not a solution to the given system of equations.
To simplify an equation you should remember we can only combine the like terms first separate the terms we can put all terms with variable in one side and the constants on the other side (4/5)x+(4/3)=2x. 2x-(4/5)x=4/3. (6/5)x=4/3. X=10/9
Answer:
(5y + 4)(2x + 7)
Step-by-step explanation:
Because (2x + 7) is the common factor, bring them together!
