Coefficient of y = 3
Solution:
Given expression is 2 · 4 + 3y.
To find the coefficient of y:
Coefficient means the number in front of the variable or term.
Here, the number in front of y is 3.
2 and 4 are not in front of y, they are separate term.
So, Coefficient of y = 3.
Hence the coefficient of y in the expression 2 · 4 + 3y is 3.
The answer is 70 because angle CGA is a 90° angle and it is split into two. so if one part of it is 20°. 90-20 equals 70°
(1) 3x+6y-12z=36
(2) x+2y-4z=12
(3) 4x+8y-16z=48
The first equation (1) is the second equation (2) multiplied by 3:
(2) x+2y-4z=12→3(x+2y-4z=12)→3x+6y-12z=36 (1)
The third equation (3) is the second equation (2) multiplied by 4:
(2) x+2y-4z=12→4(x+2y-4z=12)→4x+8y-16z=48 (3)
The equations are linearly dependent, Then the system of equations is dependent, and then consistent too.
Answer:
-9
Step-by-step explanation:
find the value of i2, which is -9, find the value of i7, which is 6
Then, add them together and multiply by the number of terms in the sequence divided by 2 (6/2=3)
