Factorising is when you put the equation in expandable brackets.
Answer:
<h2><em><u>
y = -x - 1</u></em></h2>
Step-by-step explanation:
The line is going in a negative direction. This means that the line is negative. The slope is -1. The y- intercept is the coordinate (0,-1). SO the equation is y = -x - 1.
Answer:
x^2 + 2x + 2.
Step-by-step explanation:
Write it in factor from:
(x - (-1 + i))(x - (-1 - i)) = 0
(x + 1 - i)(x + 1 + i) = 0
= x^2 + x + ix + x + 1 + i - ix - i -i^2
= x^2 + 2x + 1 + 1
= x^2 + 2x + 2.
4x+7=5x-4
-4x -4x
7=x-4
+4 +4
11=x
Answer:
B. sin35/9=sin40/b
Step-by-step explanation:
The law of sines tells you ...
sin(A)/a = sin(B)/b
Filling in the given values, you get ...
sin(35°)/9 = sin(40°)/b
