Answer: 35%
Step-by-step explanation:
Let the original price be "4x".
60% gain on 1/2 of them will be:
(1.60 × 2x) = 3.2x - 2x = 1.2x
20% gain on (1/4) of them will be:
(1.2 × x) = 1.2x - x= 0.2x
Total gain 1.2x + 0.2x = 1.4x
Total gain percent= Gain/Original price =1.4x/4x = 0.35 = 35%
Answer:
The answer is (4,3)
Step-by-step explanation:
Use desmos graphing calculator, find the points where they meet. Search desmos on google and click on the first link.
1. A (-4,2), B (-6,3), C (-4,6), D (1,4) 2. A (-4,-4), B (-6,-3), C (-4,0), D (-1,2) 3. (this part depends more on what your teacher wants for you) the quadrilateral flips over the y-axis and moves 6 down. hope this helps!
The ratio is 4:5
Divide both terms by 4
16/4 =4
20/4=5
Factor
b(b+12)=0
set to zero
b=0
b+12=0
b=-12
b=0 or -12
written as this way
b=-12,0
