Answer:
The slope of the line represented by y = -5x is "-5".
Step-by-step explanation:
y=mx+b
M=slope
b=Y-intecerpt
The answer is A because you need to find the unit rate of each cost
Since $2.80 is for 2 liters, do 2.80/2 which equals 1.4. So that’s the cost for one liter
Then, 6 half liter bottles is just 3 liters because 6*1/2= 3. Then to find the unit rate for that, do 3.90/3 which equals 1.3.
So the first option is $1.40 per liter and the second option is $1.30 per liter so the first option is more expensive- the 2-liter bottle, and the cost for that is 1.40
Hope this helps:))
Answer:
234 mm²
Step-by-step explanation:
area of each side = L x W
(15 x 3 x 2) + (15 x 4 x 2) +(3 x 4 x 2) = 234 mm²

Depreciation Formula: A = P(1 - rt)
- <em>P</em> is principle amount
- <em>r</em> is rate
- <em>t</em> is time
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>P</em> = 36001
<em>r</em> = 16% = 0.16
<em>t</em> = 3
<u>Step 2: Find Cost</u>
- Substitute in variables [Depreciation Formula]: A = 36001(1 - 0.16 · 3)
- (Parenthesis) Multiply: A = 36001(1 - 0.48)
- (Parenthesis) Subtract: A = 36001(0.52)
- Multiply: A = 18720.5
I believe it is 4.
Hope this helps!!!
