Consider the function f(x) = 5x + 7. Which statement MUST be true? A) f(1) ? f(3) = f(3) ? f(1) B) f(1) ? f(3) = f(5) ? f(3) C)
kondor19780726 [428]

Answer:

The answers are as follows for the functions.

f(1) = 12

f(3) = 22

f(5) = 32

Step-by-step explanation:

To find any of these, simply input the value in for x in the equation given.

f(1)

f(x) = 5x + 7

f(x) = 5(1) + 7

f(x) = 5 + 7

f(x) = 12

You can repeat this for each of them and it will allow you to use all of the numbers in the equations given.

My house is 20 miles from yours, but on the map it is only 4 mm away. What is the scale of the map? O A Imm = 5 mi B. I mm = 20
dlinn [17]

\huge \bf༆ Answer ༄

Let's use Unitary method to solve the question ~

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:4 \: mm \rightarrow20 \: miles

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:1 \: mm \rightarrow(20 \div 4) \: miles

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:1 \: mm \rightarrow5 \: miles

Therefore, 1 mm corresponds to 5 mile according to the map.

so, correct choice is ~

\overbrace{  \underbrace{\underline{ \boxed{ \sf A }}}}
