Answer:
No
Step-by-step explanation:
Put the values of the variables in the equation and do the arithmetic to see if it is true.
x=3, y=2
4y +3x = 4(2) +3(3) = 8 + 9 = 17 . . . . not equal to -8
The point is not on the line.
___
If you graph the equation of the line, you realize it doesn't even go through the first quadrant, so the point cannot possibly be on the line.
Answer:
Step-by-step explanation:
1. You know that:
- The roped-off area whose width is represented with <em>x,</em> it is created around a rectangular museum.
- The dimensions of the rectangular museum are: 30 ft by 10 ft.
- The combined area of the display and the roped-off area is 800 ft².
2. The area of the rectangular museum can be calculated with:
Where is the lenght and
is the width.
You have that the lenght and the width in feet are:
3. Let's call the width of the roped-off area. Then, the combined area is:
Where
4. Substitute values and simplify. Then:
<u>Given</u>:
Given that the graph of Bill's Boffo Bagel.
We need to determine the unit rate for Bill's Boffo Bagel.
<u>Unit rate:</u>
The unit rate can be determined using the formula,
Let us substitute any two coordinates that the line passes through the points in the graph.
Substituting the coordinates (2,7) and (4,14) in the above formula, we get;
Simplifying, we get;
Therefore, the unit rate for Bill's Boffo Bagel is $3.5.
Hence, the unit rate is $3.50 for 1 bagel.
Thus, Option b is the correct answer.
