An online photo services charge $20 to make a photo book with 16 pages each extra page cost a dollar 75 the cost to ship the com
Alisiya [41]

Answer:

The expression to determine the total cost in dollars is y=25+0.75x.

Step-by-step explanation:

Given:

Service charge to make a photo book = $20

Cost per extra page = $0.75

Cost to ship the complete photo book = $5

We need to write expression to determine the total cost in dollars.

Solution:

Let the number of extra pages be denoted by 'x'.

Also Let the Total cost be denoted by 'y'.

Now we can say that;

Total cost will be equal to sum of Service charge to make a photo book and  Cost per extra page multiplied by number of extra pages and Cost to ship the complete photo book.

framing in equation form we get;

y=20+0.75x+5\\\\y=25+0.75x

Hence the expression to determine the total cost in dollars is y=25+0.75x.

Write the equation of the line that passes through the points (2,-3) and (-1,-4). Show work please.
Keith_Richards [23]

Answer:

y=1/3x-3 2/3 (y equals one third times x minus three and two thirds)

Explanation:

Slope = rise (Δy) over run (Δx). Looking at the two points, (-1, -4) is furthest to the left. The x value increases by 3, and the y value increases by 1. That means slope = 1/3. Now, plug it into the slope equation y=mx+b, m being slope. We get y=1/3x+b. To find b (the y-intercept), plug in one of the points into the equation. So -4=1/3·(-1) +b. 1/3 times -1 is -1/3. Now we have -4=-1/3+b. -4-1/3= -11/3 (or negative 3 and 2/3). That means the y intercept is -3 2/3. Now we get the equation. y=1/3x-3 2/3
