Answer: True
Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.
If we plug the values, we have
So, we have to solve the following equation:
So, when we impose , knowing the value of p, we have
And so the solution is
Answer:
so if you subtract 14 from a number then multiply the difference by - you get -42

Answer:
$1,682.70
Step-by-step explanation:
- Convert the percent into a decimal by multiplying by 0.01: the percent in this problem is 6.5%, so when you multiply by 0.01, you get 0.065
- Multiply the price by your new decimal: in this case, that would mean to multiply 1580 by 0.065, which gives you 102.7. <u>Keep in mind that this is just the tax, not your final answer.</u>
- Add the tax you just calculated to the original price: add 102.7 to 1580 to get 1,682.7. That is your final answer.
Answer:
12
Step-by-step explanation:
The formula for the tangent of an angle is the length of the opposite side divided by the length of the adjacent side. Therefore, the tangent of angle x is 420/2000=0.21. Taking the arctangent of that to get the angle, you get about 12 degrees. Hope this helps!
