Answer:

$4 and for $12 , you can buy three sandwiches

Step-by-step explanation:

Part A

According to the scale used on the graph, one sandwich is equivalent to $4.

So, a sandwich cost $4

Part B

The points (3 and 12) on the graph indicates that for $12, you can buy three sandwiches

Find the cost of papering the four walls of a room 16m long ,12m broad and 8 metres high with paper 2 metres wide at Rs 50 per m

daser333 [38]

If it's $50 a meter, then the answer is:
x is the cost per meter
16x + 12x + 8x + 2x

But that answer is 5,075,020,100 and that is a ridiculously high number. I hope this helps even if it doesn't answer the question.

Answer:

B. 1 + ln 2 - ln x

General Formulas and Concepts:

Algebra II

Natural logarithms ln and Euler's number e
Logarithmic Property [Multiplying]: $\displaystyle log(ab) = log(a) + log(b)$
Logarithmic Property [Dividing]: $\displaystyle log(\frac{a}{b}) = log(a) - log(b)$

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle ln(\frac{2e}{x})$

Step 2: Simplify

Expand [Logarithmic Property - Dividing]: $\displaystyle ln(\frac{2e}{x}) = ln(2e) - ln(x)$
Expand [Logarithmic Property - Multiplying]: $\displaystyle ln(\frac{2e}{x}) = ln(2) + ln(e) - ln(x)$
Simplify: $\displaystyle ln(\frac{2e}{x}) = ln(2) + 1 - ln(x)$
Rewrite: $\displaystyle ln(\frac{2e}{x}) = 1 + ln(2) - ln(x)$

Write standard form of line that is parallel to 2x + 3y= 4 and passes through the point (1, -4)

Tresset [83]

Answer:

2x + 3y = -10

Step-by-step explanation:

First convert the line into slope intercept form to find the slope of the line.

2x + 3y = 4

3y = 4 - 2x

y = -2/3x + 4/3

The slope of the line is -2/3. Parallel lines have the same slope so the slope for a line through the point (1,-4) will be -2/3. Substitute m = -2/3 and (1,-4) into the point slope of a line.

$y --4 = -\frac{2}{3}(x-1)\\y + 4 = -\frac{2}{3}(x -1)$

Now convert the line into standard form by using the distributive property.

$y + 4 = -\frac{2}{3}(x -1)\\y + 4 = -\frac{2}{3}x + \frac{2}{3}\\3y + 12 = -2x + 2\\2x + 3y + 12 = 2\\2x + 3y = -10$
