Answer:
D. (-2,4), (5,2), (2,1), (9,2)
Step-by-step explanation:
The x-values in functions cannot repeat in any coordinate of the function.
If the ratio is 1:18, and we need to know how the other side for the ration 9:?, then we have to multiply 9x18.
9x18=162
so Laurel and Delmar are 162 km away
hope it helps! :3
A function assigns values. The inequality one-half x minus 10 greater-than-or-equal-to 0 should be satisfied.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
The domain of a function is a set of values for which the equation is satisfied. Since the function has under root values, the value which is under the root should be non-negative so that it does not give a complex number, therefore,
The inequality
satisfied to find the domain of the function f(x).
Also, we can write that 0.5x²-10≥0 for the value to be positive.
Hence, the inequality one-half x minus 10 greater-than-or-equal-to 0 should be satisfied.

In brackets everything has to multiplied by 3. It there is no sign between its always multiply!!!
this means that it has to be
3 x X + 3 x 11
this means that we can also multyplay 3 by 11 now.
and that equals to 33. There fore the expansion will be:
3 x X + 33
we can also simplify 3 x X which would be 3x (as I mentioned before, It there is no sign between its always multiply!!!)
so the expansion for 3(x+11) is 3x + 33
