Answer: A. Zero
Step-by-step explanation: If the quadratic equation is incomplete, b will always equal 0.
Answer:
8x- 38
Step-by-step explanation:
3(x-6)+5(x-4)
Distribute
3x- 18+5x -20
Combine like terms
3x+5x -18-20
8x- 38
Answer:
-16x + 14 or 2(7-8x)
Step-by-step explanation:
= 2(x + 7) – 18x
= 2x + 14 -18x
= -16x + 14
or
= 2(7-8x)
The relationship between x and y is represent as:
Since, the relationship is linear.
The standard form of equation of line is:

Consider any two set x and y values from the given relationship.
Let (-2, 10) and (-1,7.5)


The equation of the linear relationship between x and y is:
y = -2.5(x + 2) + 10
Now, to check that the point (9, -17.5) lies on the represented relationship between x and y
Substitute x = 9 and y = -17.5 in the equation y = -2.5(x + 2) + 10
y = -2.5(x + 2) + 10
-17.5 = -2.5(9 + 2) + 10
-17.5 = -2.5(11) + 10
-17.5 = -27.5 + 10
-17.5 = -17.5
Thus, LHS = RHS
Hence the point (9, -17.5) lie on the given linear relationship between x and y.
Answer: The point (9, -17.5) lie on the given linear relationship between x and y.
