For which expression is the sum of the constants greater than the sum of the coefficients?
1 answer:
Answer:
Step-by-step explanation:
The first expression is
The sum of the constants is 7+3=10
The sum of the coefficients is 3+7=10
The second expression is;
The sum of the constants is 7+1=8
The sum of the coefficients is 4+4=8
The third expression is;
The sum of the constants is 8+2=10
The sum of the coefficients is 4+8=12
The fourth expression is;
The sum of the constants is 8+4=12
The sum of the coefficients is 3+7=10
Hence the correct choice is the expression in which the sum of the constants greater than the sum of the coefficients

Answer:
The y-intercept of the function is: b=10
Step-by-step explanation:
Given the table
x y
1 8
2 6
3 4
4 2
Taking any two points to find the slope
- (1, 8)
- (2, 6)
The slope between (1, 8) and (2, 6) is:
We know that the slope-intercept form of the line equation is
where m is the slope and b is the y-intercept.
Substituting m=-2 and any point i.e. (1, 8) in the slope-intercept form of the line equation to find the y-intercept (b).
8 = -2(1) + b
8 = -2 + b
b = 8+2
b = 10
Thus, the y-intercept of the function is: b=10
