We can set up a proportion here. On map scales, the scale goes like:
“1 (length on the map) : x (real life length)”
Here, we have 2 : 8. We need to make it so the first number is 1, because thats easier for measuring.
2 : 8 /divide both sides by 2
1 : 4
The scale would be 1in : 4mi (in other words, 1 inch on the map corresponds to 4 miles in real life).
Answer:
B. x is all real numbers.
Step-by-step explanation:
On the left hand side of the y axis the values of x will become more and more negative and on the right hand side of the y axis the x values will become more and more positive.

Answer:
a=44, b= 58
Step-by-step explanation:
You look at the first triangle that gives you the two angles, and with the rule that every triangle's angles inside it need to add up to 180 degrees, you can determine that the missing angle is 46 degrees, which translates over to the other triangle, meaning that a would be 44 degrees.
The other triangle has two identical angles, being 61 degrees, which helps translate to the smaller triangle, again allowing you to infer that b is 58 degrees
Answer:
I think the answer is B.
Step-by-step explanation:
I'm just going by how it looks but I am pretty sure that <em>n</em> is -0.5 and <em>m</em> is 2.5. Therefore, if you add -0.5 + 2.5 it equals 2.0.
