It is the angle where it says "A".
Answer:
The answer should be -5.
Step-by-step explanation:
Remember that if there are two negative signs next to each other then it will turn into a positive sign, in which you get the equation -9 + 4. Your answer should be -5 when you add 4 from -9.
Answer:
y = 0x + 4 or y = 4.
Step-by-step explanation:
The slope is zero, and in other words, m = 0.
The slope intercept form is y = mx + b.
Replace m with 0.
y = 0m + b.
The y intercept is the y point on the line. Since this slope is a straight horizontal line, the y point given is the y intercept. b is the y intercept.
y = 0m + 4
Since any number times 0 is 0 you can right it as
y = 4.
(x+1)(x-2) = x(x-2) + 1(x-2)
= x.x - x . 2 + 1. x - 1 . 2
= x² - 2x + x -2
= x²-x -2
