Answer:
c=70 degree(being vertically opposite angle)
Step-by-step explanation:
Answer:
The solution to the system of equations is:
x = 2, and y = -1
Explanation:
Given the pair of equations:
4x + 5y = 3 ..........................................................................(1)
2x + 3y = 1............................................................................(2)
To solve this by elimination:
Multiply equation (2) by 2, to eliminate x
Equation (2) becomes
4x + 6y = 2 .........................................................................(3)
Subtract equation (1) from (3)
4x - 4x + 6y - 5y = 2 - 3
y = -1 ....................................................................................(4)
Multiply equation (1) by 3 and equation (2) by 5 to eliminate y
Equation (1) becomes
12x + 15y = 9 .......................................................................(5)
Equation (2) becomes
10x + 15y = 5 ........................................................................(6)
Subtract equation (6) from (5)
12x - 10x + 15y - 15y = 9 - 5
2x = 4
Divide both sides by 2
x = 4/2 = 2 ............................................................................(7)
From equations (7) and (4)
x = 2, and y = -1
Answer: There are 26000 miles that will both be due at the same time.
Step-by-step explanation:
Since we have given that
Number of miles required by new vintage = 400
Number of miles if these services have must been performed by the dealer = 13000
We need to find the number of miles from now that will both be due at the same time.
We would use "LCM of 400 and 13000":
As we know that LCM of 400 and 13000 is 26000.
So, there are 26000 miles that will both be due at the same time.
Answer:
D. They are not commutative, because f(g(x)) and g(f(x) are not equal.
