Set up a proportion
2 x
— = —
25 700
700(2)= 25(x)
1400/25=x
x=56
Answer:
A. 201.6 = 11.2f
Step-by-step explanation:
we solve for each unknown to verify which equality will require the division property:
#A. 201.6 = 11.2f
Hence, division property used.
#B. 35.4=Z ÷ 3.1
Hence, multiplication property used.
#C. t/3.2=15.1
Hence, multiplication property used.
#D. 201.6 = 11.2+c
Hence, subtractionproperty used.
Using it's concepts, we have that:
- The domain of the relation is of -2 ≤ x ≤ -1.
- The range of the relation is of -2 ≤ y ≤ 2.
- Since each value of the input is mapped to only one value of y, it is a function.
<h3>
What are the domain and the range of a relation?</h3>
- The domain of a relation is the set that contains all possible input values for the relation. In a graph, it is given by the values of x.
- The range of a relation is the set that contains all possible output values for the relation. In a graph, it is given by the values of y.
Hence:
- The domain of the relation is of -2 ≤ x ≤ -1.
- The range of the relation is of -2 ≤ y ≤ 2.
<h3>When does a relation represents a function?</h3>
A relation represents a function when each value of the input is mapped to only one value of the output.
From this graph, we have that <u>each value of x is mapped to only one value of y</u>, that is, there are no vertically aligned points, hence the relation is a function.

Answer:
answer to the question is B
Answer:
A = 32
Step-by-step explanation:
A = ½ (a + b) h
A = ½ (3 + 10) 4
A = (3+5)4
A = (8)4
A = 32
