Answer:
<em>A compound proposition that is always false is called a contradiction</em>
Step-by-step explanation:
You need to use the cosine for this and this is how you do it.
Answer:
x=2 and y=0
Step-by-step explanation:
Rewrite equations:
y=−4x+8;y=

Step: Solvey=−4x+8for y:
y=−4x+8
Step: Substitute−4x+8foryiny=

(Divide both sides by (-23)/5)
x=2
Step: Substitute2forxiny=−4x+8:
y=−4x+8
y=(−4)(2)+8
y=0(Simplify both sides of the equation)
To make that a perfect square polynomial,
follow these steps:
1. Take the co-efficient of x term: here -16
2. Divide it by 2: -16/2 = -8
3. Square it. : (-8)^2 = 64
Thats it! 64 is the missing term you need :)
