Answer:
Question 39: False
Question 43: True
Step-by-step explanation:
<u>Question 39</u>
|-4| is a solution of x ≤ 4
|-4| ⇒ This mean the absolute value of 4. The sign s are neglected.
So, |-4| is not a solution of x ≤ 4.
<u>Question 43</u>
The point (5, -1) is a solution of the equation: y = 2x − 11.
To prove this we are to substitute the point (5, -1) in the equation y = 2x − 11.
y = -1 and x = 5
y = 2x − 11 ⇒ -1 = 2(5) -11
-1 = 10 - 11
-1 = -1
Triangle FED = Triangle WXY
8n−7y−12n+5−3y
=8n+−7y+−12n+5+−3y
Combine Like Terms:
=8n+−7y+−12n+5+−3y
=(8n+−12n)+(−7y+−3y)+(5)
=−4n+−10y+5
It doesn't have to be called width
So just use the formula.
A=h×w
A=2×8.5
A=17
The area of the rectangle is 17 meters
