Answer:
x = -4
B is the answer
Step-by-step explanation:
To find the axis of symmetry, we will need to find the vertex of this function.
I have provided you with the steps to find the vertex.
After finding the vertex, pay attention to the x-value of the vertex because that is the axis of symmetry too. Hope this helps :)
Isolate the variable by dividing each side by factors that don't contain the variable.
n = 22
Answer:
102

Answer:
Step-by-step explanation:
Both of these questions involve proportions. You can set up an equation using equivalent fractions. You want to express to ratio of cm to km in Part A. Given the scale factor 5 cm = 2 km, then we can let c = the number of cm that represent an actual distance of 5 km. The following equation can be formed:
5/2 = c/5
Both of these fractions are a ratio of cm to km. To solve, we can cross-multiply.
2c = 25
c = 12.5 cm
You can use a similar process for Part B.
