Answer:
The answer is 3rd point
Step-by-step explanation:
By looking at the table :
10-10.99,
$15.95 (1 dot)
20-29.99,
$21.52, $25.55, $27.78, $29.90 (4 dots)
30-39.99,
$33.98, $36.77 (2 dots)
40-49.99,
$43.44 (1 dot)
50-59.99,
$51.25 (1 dot)
60-69.99,
$60.54, $64.56, $67.89 (3 dots)
Then you can determine number of dots in each range.
Answer:
A 2 term polynomial 3x^2-3
Answer:
B
Step-by-step explanation:
The line going with the graph for 1 day meets in-between 1, and 2 dollars, so it is 1.50
I don’t understand u sorry ;-;
Notice they are all right triangles. You will need Pythagorean theorem, which is a² + b² = c²
If you write down all the "equations" you can find, it is the following:
y² + 4² = x²
5² + y² = z²
x² + z² = 9²
Substitute them into one equation:
y² = x² - 4²
z² = 5² + (x² - 4²) <em>Notice that the y² is replaced with what you found </em><em>above</em>
x² + (5² + x² - 4²) = 9² <em>Notice that the z² is replaced with what's </em><em>above</em>
Now that it is just one line with one variable, you should be able to find value of x easily.
The answer is 6 if my calculations are correct.
