Answer:
49
Step-by-step explanation:
Put the numbers in place of the variables and do the arithmetic.
g(f(3)) = g(2·3 +1) = g(7) = 7²
g(f(3)) = 49
Part A:
[$25-( $0.50×22)]÷$2=n
Part B:
[$25-($0.50×22)]÷$2=n
[$25-($11)]÷$2=n
[$14]÷$2=n
7=n
Part C: Brandon purchased 7 meals last month.
Answer:
B. 
Step-by-step explanation:
we know that
If a ordered pair is a solution of a linear equation. then the ordered pair must satisfy the linear equation
In this problem we have

<u>verify each case</u>
case A) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is not true
therefore
The ordered pair case A) is not a solution
case B) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is true
therefore
The ordered pair case B) is a solution
case C) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is not true
therefore
The ordered pair case C) is not a solution
case D) 
substitute the value of x and the value of y in the linear equation and then compare

-----> is not true
therefore
The ordered pair case D) is not a solution
Step-by-step explanation:
To find the sum of the measures of the intereor angles of each convex polygon
we using formula
<h3>#4</h3>
we can put the value of x is 54
then,
<h3>#5</h3>
we can put the value of x is 19
then,
#6
we can put the value of x is 292
then,


- =》 52200°
#7
we can put the value of x is 5
then ,


- =》 540°
We can add in any order. So 5x+y is the same as y+5x
5x+y = 10
y+5x = 10
y+5x-5x = 10-5x ... subtract 5x from both sides
y+0x = -5x+10
y+0 = -5x+10
y = -5x+10
Answer: y = -5x+10
Note: this is in y=mx+b form where m = -5 is the slope and b = 10 is the y intercept
