one way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
Step-by-step explanation:
graph
Mr. Sato needs 9 more magnets. There are 12 total pairs and he has given 9 their magnets. He needs to give three more pairs three magnets each. 3*3 = 9.
3x = 21
devide each side by 3
3x = 21

I got this bc 25*12=300 and 300-250=50
Answer:
Step-by-step explanation:
The value of 
can be easily obtained by recalling what the log notation means. Recall that logarithms are another way of writing exponents.
With the notation 
we want to find an exponent (logarithms are exponents). So read this expression as: what is the exponent we need to use on base "7" to get the number 343? That exponent is the answer to the question.
Equivalently in exponential form: What is the exponent "x" such that: 
. The answer to this is : "3" (the exponent 3 on base "7" renders 343)
"3" is the answer because
