((–7) + (3 + i)) - (2 - (6 + i)) =-9 + 9 i
Answer:
B,-7
Step-by-step explanation:
convert the formualt into slope intercept form by adding the 3 and distributing the -2
then you will get y=-2x-7
in slope intercept the B slot is the y intercept, and in this equation it is -7
Then
2x = 3.6
x = 3.6 / 2
x = 1.8
answer is B. 1.8
Substitute (-4, 3) into the equation of curve
3 = 16a - 4b - 13
4a - b = 4
b = 4 - 4a ---- (1)
dy/dx = 2ax + b
At (-4, 3), dy/dx = 0
-8a + b = 0
b = 8a ---- (2)
Fom (1) and (2),
4 - 4a = 8a
4 = 12a
a = 1/3
b = 8/3.
It is basically asking you to find where the equation crosses the d-axis. 2x^2 + 12x -14 = (x-1)(2x-14). x-1=0. x=1. 2x-14=0. 2x=14. x=7. The solution/roots/zeros would be 1 and 7
